Shopping Notes: Before purchasing a motor, determine the speed for one minute and select the closest speed in our reduction ratio selection table. When the speed-regulating motor is no-load, the motor can be infinitely regulated, and the speed can be adjusted from the speed to 0. However, after the motor is equipped with equipment and has a load, please pay special attention to. When the load is relatively small and the motor does not work continuously for a long time, the governor must not be lower than 50% of the full speed. When the load is relatively large and the motor works continuously for a long time, the governor must not be lower than 70% of the full speed.
