Working principle:
When the motor starts, it must overcome its inertia and the reaction force of the load. Therefore, a large current and torque are required when the motor is started. When turning normal, in order to save energy and large torque, it is necessary to reduce the voltage, and add a set of auxiliary to the motor coil. It only works when it is turned on, and it is normal after disconnection. When starting, the PTC thermistor is connected in series with the auxiliary coil, and the PTC thermistor enters high The effect can be achieved by cutting off the secondary coil in the resistance state.
