Torque Motor FAQ
Q: What is the main difference between a torque motor and a conventional servo motor?
A: The primary difference lies in their performance characteristics. A torque motor is specifically designed to provide high torque at low speeds, typically operating without a gearbox. Conventional servo motors usually require gear reduction to achieve similar torque levels, which introduces backlash and reduces system efficiency.
Q: Can torque motors be used for continuous rotation applications?
A: Yes, torque motors can operate in continuous rotation mode, though they are optimized for applications requiring high torque at relatively low speeds. For continuous high-speed operation, proper cooling systems must be implemented to prevent overheating.

Torque Motor FAQ
Q: What maintenance is required for torque motors?
A: Torque motors are designed for minimal maintenance thanks to their brushless design. Periodic checks should include bearing inspection (typically every 10,000 operating hours), cooling system maintenance, and electrical connection verification. Unlike geared systems, there are no gearbox oil changes or gear wear issues to address.
