    20W AC torque motor with high torque and low speed, will operate satisfactorily on 50 or 60 Hz. Our torque motor has high starting torque and sloping characteristics, allowing speed control simply by changing the voltage of the power supply. Special rotor provides excellent performance for holding, winding, and tensioning applications.

    Tips: What is the starting torque, rated torque, maximum torque and overload capacity of a motor?

    1. Starting torque. When the motor is started immediately after the power is turned on, the torque when the speed n = 0 and the slip s = 1 is called the starting torque of the motor.
    2. Rated torque. The motor can work for a long time under the rated voltage and rated frequency. The maximum allowable torque output on the shaft is called the rated torque.
    3. Maximum torque. The maximum torque produced by an electric motor is called the maximum torque of the motor. If the load torque is greater than the maximum torque of the motor, the motor can not start.
    4. Overload capacity. The ratio of the maximum torque to the rated torque is called the overload capacity of the motor, which is an important data to measure the short time overload and operation stability of the motor. The motor's overload capacity is usually between 1.8 and 2.5 times.

    In this video, you will see wiring and testing a ATO single-phase 220V, 50Hz, 6W, 1250rpm torque motor with gearbox.
    Firstly, we use a 250V 15A switch to transfer the direction of rotation of the motor.
    Secondly, apply a 0.8μF capacitor to both ends of the blue and white wires of the motor and connect it to the transfer switch. The intermediate terminal of the transfer switch is connected to the power supply.
    Finally, turn on the power and test.

    The rate is IP20.
    My question about 20W AC gear motor
    For your 20W AC gear motor, and if I want to change the ratio, I have to buy another motor? Gearbox cannot be modified?
    From: Ronparr | Date: 20/07/2021
