Direct drive and propulsion
Application-led motor solutions for precise direct drive, mobile machinery and controlled propulsion.
Product families
Start with direct-drive torque motors for integrated rotary motion, or traction motors for vehicle and mobile-machine propulsion.
Matched stator and rotor sets for compact direct-drive mechanisms, with housed constructions available when a bearing-supported, ready-to-integrate motor is preferred.

Two coordinated technical sections provide a practical starting point without overcrowding the page.
| Range | Outside diameter (mm) | Through bore (mm) | Continuous torque (N·m) | Peak torque (N·m) | Maximum speed (rpm) | Typical supply | Commercial application focus |
|---|---|---|---|---|---|---|---|
| FM60 | Approx. 60 | 16–29 | 0.4–1.5 | 1.2–5 | Up to 4,300 | 24–48 VDC | Robotics, mobile axes |
| FM110 | 105–110 | Approx. 50 | 1.5–12 | 4–55 | Up to 3,500 | 48 VDC–400 VAC | Medical, automation |
| FM160 | 133–160 | 55–76 | 3–45 | 8–155 | Up to 3,000 | 48 VDC–600 VAC | Semiconductor, rotary axes |
| FM260 | 250–260 | Approx. 150 | 44–225 | 150–1,075 | Up to 1,500 | 400–600 VAC | Large direct-drive axes |
Representative values provide an initial selection guide. Maximum torque, speed and power figures are not necessarily simultaneous operating points; the continuous and peak duty, winding, cooling, inverter and mechanical interfaces must be confirmed for the application. Additional sizes and custom constructions can be reviewed where the required solution is not displayed.

The two technologies share compact electromagnetic design principles but solve different mechanical duties.
| Selection factor | Torque motors | Traction motors |
|---|---|---|
| Primary function | Direct-drive positioning and rotary motion | Vehicle or mobile-machine propulsion |
| Operating character | High torque at low or moderate speed | Starting torque across a wider speed range |
| Typical integration | Built into the customer mechanism | Integrated with wheel, axle, transmission or driveline |
| Thermal approach | Housing-assisted, air or liquid cooling | Duty-cycle-led air or liquid cooling |
Preliminary selection framework
These inputs are reviewed together before a motor platform, winding, cooling method or mechanical interface is proposed.
Engineering and customisation
Options are reviewed as a complete operating system, not as isolated catalogue features.
Industries and applications
Direct-drive motors support accurate rotary motion; traction motors provide controlled propulsion for mobile equipment. Each solution is configured around its operating duty.
Direct-drive torque and position control for rotary joints and indexing axes.
Controlled rotary motion with fewer transmission elements for precision positioning.
Traction motor platforms matched to vehicle load, wheel speed and duty cycle.
Efficient propulsion configured around the battery, control and vehicle envelope.
Repeatable movement for handling equipment, transfer systems and mobile loads.
Low-speed traction engineered for payload, gradients and operating time.
Propulsion matched to rough terrain, environmental exposure and thermal duty.
Custom motor, feedback and drive integration for equipment-specific motion.
Continue through the motion system
SDT can coordinate motor selection, mechanical integration, feedback and the matched drive or controller.
