What is a torque motor?
A torque motor is a specialized form of DC electric motor which can operate indefinitely while stalled, without incurring damage. Torque motors are a special class permanent-magnet synchronous motors. Since the payload is directly connected to the rotor without the use of transmission elements, torque motors are classified as direct drives. In direct drive torque motors, the motor directly drives the load which eliminates the used of transmission or gearbox.
Why adopt torque motor?
1. Reduce the cost
2. Easy integration
3. Dynamic performance
4. Wide torque speed range
Han’s Torque Motor Introduction
Han's motor has developed several torque motors for various application requirements: F series frame torque motors based on optical grating encoders and HANS series frame torque motors based on self-developed time grating encoders, which are mainly used in the automation industry. BI series frameless torque motors are mainly used in the machine tool industry. Han's torque motors have a continuous torque range from 0.062Nm to 3300Nm and a peak force range from 0.46Nm to 5500Nm,which is suitable for various application scenarios.
Based on self-developed encoders, HANS series frame torque motors with high precision, high torque density and fast delivery.
Below table is the comparison between Han's Motor and other famous foreign brands.
