9Pcs Refrigerator Spare Parts Parts 2 3 4Pin 12 15 22Ohm Ptc Relay Accessories

perfect spare part for refrigerator, easy to install.
Working principle: When the motor starts, it must overcome its own inertia and at the same time overcome the reaction force of the load. Therefore, the motor needs a larger current and torque when starting. When the rotation is normal, in order to save energy, the required torque has to be greatly reduced.
Add a set of auxiliary coils to the motor, which only works when starting, and it will be disconnected after normalization. Connect the PTC thermistor in series with the starting auxiliary After starting the coil, the PTC thermistor enters a high resistance state to cut off the auxiliary coil, which can achieve this effect.
