Who Nidec is
Nidec is a Kyoto-based motor manufacturer that describes itself as the world’s largest comprehensive motor maker, with around 300 group companies. Its products span tiny precision motors for electronics through to large industrial motors, automotive systems, home appliance motors, machine tools and power transmission equipment.
For motion control engineers, Nidec matters in two places. The first is precision gearing for servo axes and robots, made by NIDEC DRIVE TECHNOLOGY CORPORATION, which Nidec’s reducer pages name as the manufacturer. The second is servo drives and motors, which Nidec sells under the Control Techniques brand, covered in its own profile on our site. This page focuses on the gearing side and on Nidec as the owning group.
History and ownership
Shigenobu Nagamori founded Nippon Densan Corporation in Kyoto in 1973 with 20 million yen of capital, starting production of small precision AC motors that August. The company’s official establishment date is 23 July 1973. It listed on the first section of the Tokyo Stock Exchange in 1998 and is now on the Prime Market under code 6594. Capital stood at 87,784 million yen and consolidated headcount at 104,285 on 31 March 2025.
Growth has come largely through acquisition. Relevant milestones for motion include a stake in Japan Servo in 2007; the 2017 purchase of Emerson’s motors, drives and power generation businesses, which created Nidec Control Techniques and Nidec Leroy-Somer; Nidec-Shimpo’s acquisition of German reducer maker MS-Graessner in 2018; and the 2019 acquisitions of DESCH Antriebstechnik and Systeme + Steuerungen. In 2021 Nidec bought Mitsubishi Heavy Industries Machine Tool, and in April 2023 it changed its Japanese corporate name to Nidec Kabushiki Gaisha.
Precision reducers for motion axes
FLEXWAVE strain wave gearing
FLEXWAVE is Nidec Drive Technology’s strain wave range. It comes in a flat “D” type and a high-torque “B2” type, each as a component sub-assembly (WPC), a simple contained assembly (WPS) or a complete unit (WPU) with hollow or input shaft. Sizes run from 35 to 100, ratios from 50 to 160, and allowable torque reaches 382 Nm on the largest high-torque units. Smart-FLEXWAVE adds built-in torque, temperature and position sensing, which is useful for collaborative robot joints. Our guide to harmonic vs planetary vs cycloidal gearing explains where strain wave gears suit best.
ABLE coaxial servo planetary reducers
The ABLE family is Nidec’s servo planetary range. The ABLE VRB (square flange, sizes 042 to 220) and ABLE VRL (round flange, sizes 050 to 235) both cover ratios of 3 to 100 and allowable torque up to 1,500 Nm. The ABLE VRS extends to 2,400 Nm in sizes up to 240, and the flange-output ABLE VRT reaches 3,300 Nm in nine sizes up to 285. Ultra-high-precision versions of the VRS, VRB and VRT are listed for ratios of 4 to 10. Nidec publishes allowable torque on its overview pages; backlash and rated torque are in the series catalogues.
Right-angle and large reducers
For right-angle axes, the ABLE EVS covers ratios of 3 to 100 and allowable torque from 12 to 1,920 Nm in seven sizes, with the EVT, EVRG, NEV and STH completing the orthogonal and hollow-shaft line-up. KINEX large high-precision reducers come in solid-shaft EH-N and hollow-shaft EH-C versions, and the DESCH and GRAESSNER brands add high-precision and right-angle gearboxes from Nidec’s German acquisitions. See our gearboxes hub for selection basics.
Motors and drives
Nidec’s small precision motor range includes brushless DC and stepping motors, among many other types. For servo drives and servo motors, though, the group’s industrial offer is Control Techniques: the Unidrive M and Digitax HD drives and Unimotor servo motors, designed and built in Newtown, Wales. Engineers specifying a complete axis often combine a Control Techniques drive and motor with a Nidec Drive Technology reducer, though nothing obliges that pairing.
Industries served
Nidec’s reducer pages tag robotics, mobility, medical and industrial machinery as applications, and describe the high-torque FLEXWAVE B2 as suited to robots and machine tools. ABLE servo reducers are general-purpose servo gearheads for indexing, handling and packaging axes. Our robotics and cobots page covers joint gearing requirements in more depth. When comparing Nidec reducers with other makes, ask for rated output torque, peak (emergency stop) torque, backlash or lost motion in arcminutes and the permitted input speed, because the allowable torque shown on Nidec’s overview pages is not the same figure every maker publishes.
Global and UK presence
Nidec operates worldwide from Kyoto through its group companies. In the UK, the largest motion-related operation is Nidec Control Techniques Ltd at The Gro, Newtown, Powys. For reducers, Nidec directs enquiries through its online enquiry forms and the Nidec Drive Technology catalogue and selection pages linked from nidec.com.
Sourcing Nidec parts through Specify Motion
Specify Motion is independent of Nidec and is not affiliated with it. We can help you source Nidec reducers and other motion parts for an existing machine, or propose equivalent gearboxes from our supply network on published figures where a second source makes sense. The find a replacement form is the quickest way to send us a part number or nameplate.
