3 Phase Switched Reluctance Motor Market

Honda invested in Enedym, a Hamilton, Canada, maker of switched reluctance motors that use no magnets or rare earths, through Honda Xcelerator Ventures, Enedym announced on 20 October 2025, citing more than 70 patents and pending applications. The 3 phase switched reluctance motor market covers three-phase switched reluctance motors (SRMs), typically 6/4 and 12/8 pole designs, sold with their power converters and controllers for industrial, building, mobility, appliance and aerospace uses. Douglas Insights sizes it at USD 540 million in 2025, about 600,000 motor-and-drive sets at an average USD 900 each, and at USD 1.50 billion in 2035, a 10.74% compound annual growth rate (CAGR). The study sits beside our Electric Vehicle Traction Motor Core Market, 3 Phase Filter Market and Electric Control Panel Market reports; every figure follows the Douglas Insights research methodology.

Which applications buy the most 3 phase switched reluctance motors: pumps and compressors, mining, HVAC or e-mobility?

Industrial pumps, fans and compressors buy the most, 38.0% of 2025 switched reluctance motor value or about USD 205 million, Douglas Insights estimates. E-mobility and traction grows fastest, 16.8% a year to USD 408 million by 2035.

Pumps, fans and compressors lead because a switched reluctance machine runs at high speed without a magnet rotor that could crack or demagnetise, so it can drive a centrifugal pump or screw compressor directly. Nidec’s U.S. MOTORS range lists rare-earth-free SR motors with IE4-compatible SR Drives at up to 6,300 rpm for direct-drive centrifugal pumps and 4,500 rpm for screw compressors, plus conveyor versions with more than 300% overload torque, its product page shows. Douglas Insights estimates about 70,000 industrial pump, fan and compressor sets in 2025; their value grows 9.4% a year to USD 504 million.

Mining, textile and heavy machinery, USD 97.2 million, grows 8.2% on high starting torque for shearers, conveyors and looms. E-mobility and traction, USD 86.4 million, grows fastest at 16.8%: Enedym ran a luggage-tugger pilot with Toyota Tsusho at Hamilton airport and aims to build more than 1,000 units in Hamilton within 12 months, Electric Autonomy reported on 20 November 2025. HVAC, USD 75.6 million, grows 10.6%, appliances 7.5% and aerospace 11.0%. Application values for 2035 sum to USD 1.51 billion, 1.07% above the headline.

Which power ratings of switched reluctance motor earn the most: under 7.5 kW, 7.5 to 75 kW or above 75 kW?

Machines rated 7.5 to 75 kW earn the most, 41.0% of 2025 value or about USD 221 million, Douglas Insights estimates. Machines under 7.5 kW grow fastest, 11.6% a year from USD 184 million to USD 550 million by 2035.

The 7.5 to 75 kW band leads because it covers most pumps, compressors, conveyors and commercial-vehicle traction units, and because three-phase converters at this size are cheap enough to compete with an induction motor on a variable-speed drive. Electric motor systems used 13,462 TWh, or 53% of global electricity, in 2023, the IEA 4E Electric Motor Systems Platform’s December 2025 policy brief shows, and most of that runs through mid-size industrial machines. Douglas Insights estimates that a 7.5 to 75 kW set averages about USD 2,200, about 100,000 sets in 2025.

Machines under 7.5 kW, USD 184 million, grow fastest at 11.6% as small e-mobility traction, fan and appliance makers seek magnet-free designs. Machines above 75 kW, USD 135 million, grow 9.8%, held back by the size of the converters they need. Rating values for 2035 sum to USD 1.50 billion, 0.20% below the headline.

What drives switched reluctance motor demand: rare-earth risk, efficiency rules, e-mobility or new investment?

Unit shipments rise 13.0% a year in our base case, from about 600,000 sets in 2025 to about 2.04 million in 2035. Four drivers add 16.0 points of gross growth; three restraints remove 3.0 points.

Rare-earth supply risk: 5.50 points

Rare-earth risk is the largest driver, worth 5.50 points. China’s commerce ministry put export controls on samarium, gadolinium, terbium, dysprosium, lutetium, scandium and yttrium, including terbium- and dysprosium-bearing NdFeB magnets, in Announcement No. 18 of 4 April 2025, and China’s permanent magnet exports fell 74.26% on the year to 1,238 tonnes in May 2025, SMM reported on 20 June 2025. China mined about 270,000 of the world’s 390,000 tonnes of rare-earth oxide in 2025, about 69%, the US Geological Survey’s Mineral Commodity Summaries 2026 shows. Douglas Insights estimates that each supply shock of this size moves about 2% of new motor-design starts towards magnet-free machines.

Efficiency rules and variable-speed drives: 4.00 points

Efficiency rules add 4.00 points. The EU’s Regulation (EU) 2019/1781 has required IE3 for three-phase motors from 0.75 kW to 1,000 kW since July 2021 and IE4 for 75 kW to 200 kW since July 2023, with projected savings of about 106 TWh a year by 2030, the European Commission states. The US Department of Energy’s motor standards take effect on 1 June 2027, requiring IE4-level efficiency for many mid-range motors, its Federal Register rule shows. Douglas Insights estimates that about 35% of new industrial switched reluctance sets in 2025 were sold to meet an IE4 or IE5 target.

E-mobility, ground support and off-highway traction: 4.00 points

E-mobility adds 4.00 points. Advanced Electric Machines won a seven-figure development contract with a global Tier 1 for its rare-earth-free reluctance motor for high-volume passenger cars, running at up to 30,000 rpm, Charged EVs reported on 27 October 2025. Enedym has an unnamed contract for scooter and motorcycle motors for Asia and built a switched reluctance prototype to replace a permanent-magnet motor in a Cadillac Lyriq, The Globe and Mail reported. Douglas Insights estimates about 95,000 traction sets in 2025, mostly airport tuggers, two-wheelers and off-highway machines.

New investment in magnet-free capacity: 2.50 points

Investment adds the last 2.50 points. Advanced Electric Machines raised GBP 16 million led by Barclays Climate Ventures, PXN Ventures, Northstar Ventures and the Low Carbon Innovation Fund, plus an Innovate UK loan, for capacity at Washington in north-east England and a high-torque commercial-vehicle platform, Newcastle University announced in August 2026. The US Department of Energy opened about USD 1 billion of critical-minerals funding in August 2025, including a USD 50 million accelerator covering the magnet supply chain, its funding notice states. Summed, 5.50 + 4.00 + 4.00 + 2.50 = 16.0 points, a Douglas Insights estimate.

What holds switched reluctance motors back: torque ripple and noise, rival magnet-free designs or start-up funding?

Three restraints remove 3.0 points a year from unit growth: torque ripple, noise and converter cost take 1.40 points, rival magnet-free motor types 1.00 point and thin start-up funding 0.60 points.

Torque ripple and acoustic noise are the heaviest drag. Switched reluctance machines pull the rotor pole by pole, so torque pulses and the stator vibrates unless the controller shapes each phase current; Tokyo Institute of Technology’s group under Professor Akira Chiba won an IEEE paper award for work on reducing that noise, the university reported on 8 July 2025. Douglas Insights estimates that a three-phase switched reluctance converter costs 10% to 20% more than a standard six-switch inverter of the same rating, which slows adoption in cost-led appliance and fan markets.

Rival designs take 1.00 point. Astemo is developing a rare-earth-free synchronous reluctance EV drive of 180 kW plus a 135 kW auxiliary unit, aimed at about 2030, Drives & Controls reported on 13 January 2026, and India’s Chara Technologies raised INR 52 crore to lift synchronous reluctance output from 20,000 to 100,000 units a year, EVreporter reported on 13 October 2025. Funding takes the last 0.60 points: Turntide Technologies, once known for switched reluctance smart motors, unveiled an axial-flux drive unit for CONEXPO, Power Transmission Engineering reported on 13 February 2026.

Which region buys the most 3 phase switched reluctance motors, and where does demand grow fastest?

Asia Pacific buys the most switched reluctance motors, USD 248 million or 46.0% of 2025 value, and also grows fastest, 11.6% a year to USD 744 million by 2035.

Asia Pacific leads because, Douglas Insights estimates, China’s mining, textile and oilfield machinery builders take about a third of the world’s switched reluctance sets for their high starting torque, while Japanese research groups and investors such as Honda treat the technology as a magnet hedge. China’s minimum motor efficiency standard GB 18613-2020 took effect on 1 June 2021, MPR China Certification notes, pushing variable-speed sets into new plants. Regional value grows 11.6% a year to USD 744 million, a Douglas Insights estimate.

North America, USD 130 million, grows 10.4% as the Department of Energy’s motor rule, with compliance from 1 June 2027 per the Federal Register, lifts efficiency floors. Europe, USD 119 million, grows 10.4% on EU ecodesign rules and UK investment in Advanced Electric Machines and Turntide, which was chosen for the GBP 17 million Project SUPREME to automate motor production in Gateshead, its release of 10 August 2026 states. Latin America, USD 27.0 million, grows 8.0% and the Middle East and Africa, USD 16.2 million, 8.5%. Regional values sum to USD 598 million in 2026, in line with the headline, and USD 1.51 billion in 2035, 0.63% above it.

Which companies lead the 3 phase switched reluctance motor market?

Nidec leads three-phase switched reluctance motors with about 14% of 2025 value, Douglas Insights estimates, ahead of Turntide Technologies at about 3%, Advanced Electric Machines at under 1% and Enedym at under 1%; regional makers in China, India and Europe share about 82%.

Nidec is the best-known motor major with a dedicated switched reluctance catalogue: its SR Drives business supplies IE4-compatible variable-speed sets for centrifugal pumps, screw compressors and conveyors, its product page shows. Its switched reluctance revenue is not disclosed, so our 14% share is a Douglas Insights estimate built from catalogue breadth and installed industrial base.

Advanced Electric Machines earned about EUR 3.3 million in 2024, against EUR 2.5 million in 2023 and about EUR 6 million in 2022, with a 2024 loss of about EUR 9.6 million partly from the insolvency of customer Tevva, NewMobility News reported on 22 October 2025; it targets passenger-car series production by the end of the decade. Enedym’s chief executive Ali Emadi estimates magnets are 40% to 50% of motor cost in some permanent-magnet designs, per Electric Autonomy.

Turntide earlier sold its automation division to BrainBox AI to focus on motors and power electronics, Sustainable Tech Partner reported on 29 May 2024, and its new axial-flux unit claims 53% higher torque density than radial-flux designs, per Power Transmission Engineering. Douglas Insights expects at least one Asian or European motor major to buy or license a switched reluctance start-up before 2030.

How much does a 3 phase switched reluctance motor cost, from an appliance set to a 200 kW compressor drive?

A three-phase switched reluctance motor-and-drive set sells for an average USD 900 in 2025, Douglas Insights estimates, from about USD 120 for an appliance or tool set to about USD 40,000 for a 200 kW compressor drive.

The price ladder follows rating and the converter. Appliance and tool sets sell for about USD 120 to USD 250, HVAC fan sets for USD 300 to USD 600, e-mobility traction sets for USD 400 to USD 2,500, 7.5 to 75 kW industrial sets for USD 1,500 to USD 9,000 and sets above 75 kW for USD 15,000 to USD 60,000, Douglas Insights estimates; the converter and controller take about 45% of system price. The magnet-free rotor removes the most volatile cost line: China’s PrNd oxide traded at 730,000 to 740,000 yuan a tonne on 2 April 2026, SMM reported, against a 2025 average of USD 69 a kilogram, per the USGS.

Average set price falls 2.0% a year in the base case, to about USD 735 in 2035, because small e-mobility and fan sets gain share and converter silicon gets cheaper. Industrial set prices fall only about 1% a year, while sub-7.5 kW set prices fall about 3%, Douglas Insights estimates. One USD 100 change in the average set price shifts 2025 market value by USD 60 million.

What if magnets stay scarce or prices ease: how large is the market in 2035?

The 3 phase switched reluctance motor market ends 2035 between USD 1.04 billion and USD 2.20 billion across our three cases, around a base of USD 1.50 billion. Rare-earth supply and traction wins set most of the spread.

In the slower case China keeps magnet exports flowing under general licences, NdPr eases and synchronous reluctance and ferrite designs win most magnet-free programmes, taking 3.5 points off units and 0.5 points off price. In the faster case controls return after the current suspension, a light-vehicle maker puts a switched reluctance traction motor into series production and IE5 rules spread, adding 3.5 points of units and 0.8 points of price. One extra point of yearly revenue growth adds about USD 140 million to 2035 value, a Douglas Insights estimate.

Live signals sit near the base case. The GBP 16 million AEM raise, the Honda investment in Enedym and the Tier 1 contract point up; Turntide’s move to axial flux and China’s general export licences point down. The signal to watch is China’s decision on the controls suspended until 10 November 2026, per CGTN: if they return, Douglas Insights would move toward the faster case.

Which rules shape switched reluctance motors, from EU ecodesign to China’s rare-earth export controls?

Three rule sets shape switched reluctance motors: motor efficiency minimums in the EU, US and China, the IEC efficiency classes for variable-speed motors, and Chinese export controls on rare earths and magnets that set the price of the rival technology.

The efficiency layer sets the floor. Regulation (EU) 2019/1781 also requires IE2 for variable speed drives, the US rule takes effect on 1 June 2027, and the Department of Energy decided not to amend small electric motor standards in a determination effective 16 March 2026, its 13 February 2026 notice shows. IEC TS 60034-30-2 defines classes up to IE5 for variable-speed AC motors, covering switched reluctance machines, per the standards catalogue, which lets makers compare the motor-and-drive set as one unit.

The rare-earth layer sets the competition. China’s October 2025 package would have required licences from 1 December 2025 for foreign-made items with 0.1% or more Chinese rare-earth content by value, Mayer Brown summarised, but was suspended until 10 November 2026 while the April 2025 controls stayed in force, CGTN reported on 7 November 2025. In the US, the Department of Defense agreed a 10-year NdPr price floor of USD 110 a kilogram with MP Materials, its 10 July 2025 filing shows, a floor that raises the long-run cost of magnet motors, a Douglas Insights reading.

Douglas Exclusive: the Magnet Parity Price

The Magnet Parity Price is a Douglas Insights model of 8 inputs: 3 price records, 2 policy records, 1 trade record and 2 company records, listed below. It finds the NdPr price at which a three-phase switched reluctance set costs the same as an interior permanent-magnet set of equal rating.

The finding, a Douglas Insights estimate: at the 2025 average of USD 69 a kilogram, a 30 kW switched reluctance set costs about 8% more than a permanent-magnet set once its larger converter is counted, and each USD 10 rise in NdPr narrows that gap by about 1.2 points. Parity falls at about USD 136 a kilogram. At the April 2026 price of about USD 103 a kilogram, per SMM, the gap is about 3.9%, and at the USD 110 US floor about 3.1%.

The parity price changes how to read the market. Buyers do not need NdPr above parity to switch; a gap under 5% is small enough that supply security decides many industrial orders. If NdPr holds above USD 100 a kilogram through 2027, Douglas Insights would expect switched reluctance sets to win about 1 in 20 new mid-size pump and compressor drives, up from about 1 in 40 today.

How does the methodology turn 600,000 sets into USD 540 million?

Our methodology multiplies about 600,000 three-phase switched reluctance motor-and-drive sets in 2025 by an average USD 900 each to reach USD 540 million, then grows units 13.0% a year and price minus 2.0% a year.

The model covers 6 applications, 3 power ratings and 5 regions, using 54 data points, 22 sourced and 32 modelled. Units come from a build of about 70,000 industrial pump, fan and compressor sets, 25,000 heavy-machinery sets, 95,000 traction sets, 160,000 HVAC sets, 240,000 appliance and tool sets and 10,000 aerospace and defence sets, Douglas Insights estimates drawn from company disclosures and installed-base data. Arithmetic: 600,000 x USD 900 = USD 540 million; USD 540 million x (1.130 x 0.980)^10 = USD 1.50 billion. Units reach about 678,000 in 2026 and 2.04 million in 2035.

Two cross-checks agree. First, AEM’s EUR 3.3 million 2024 revenue is about 0.7% of our 2025 market, matching our under-1% share. Second, Enedym’s target of more than 1,000 units a year in Hamilton is about 1% of our 95,000 traction sets, consistent with a start-up in pilot production, a Douglas Insights cross-check. AI tools help draft the text and automated checks test the arithmetic and links; the Douglas Insights research desk chooses the sources, builds the model and approves publication, as our editorial standards explain.
