Position sensor is composed of three parts of a brushless DC motor system, but also a symbol from the brush DC motor. Its role is to position in the movement detection in the process of the main Car Temperature Sensorrotor, rotor magnet pole position signal into electrical signal, provide the information for the correct logic switching circuit, the turn-on and cut-off control them, which cause the current to the armature winding of the motor changes with the rotor position in order of commutation, car sensorform a rotating magnetic field the air gap step type, drive permanent magnet rotor rotating continuously. Application of position sensor, reduce noise, improve the service life of motor operation and performance of the motor, at the same time to reduce the energy dissipation effect.
