    Tips: Tendency for servo motors

    1. Small size and high efficiency: The latest permanent magnet material and optimized motor design are adopted, which can make the servo motor in small size produce very high torque. When the same model of motor matches different drivers, the maximum output torques is different. When the motors with same volume use different winding patterns and different number of poles, the output torques is different, too.
    2. Impact torque: The maximum torque can reach several times the rated torque.
    3. High-performance magnetic materials and high magnetic energy products are used.
    4. Both the motor and the driver can be equipped with temperature monitor.
