Working Principle:
When the motor starts up, it has to overcome its inertia and the reaction force of the load. Therefore, it needs large current and torque when the motor starts up. When turn to normal, in order to save energy, large torque and need a drop, add a set of auxiliary to motor coil, work only at boot time, normal after it is disconnected, the PTC thermistor series auxiliary coil at startup, starts the PTC thermistor into the high impedance state to cut off the secondary coil, just can achieve the effect.
