Abstract :
An automotive electric air conditioning system is described. The system utilizes a brushless DC motor with back electromotive force (EMF) sensing in lieu of a position sensor. A 96 V power supply is proposed to reduce line current to well under 50 A. The motor and the back EMF sensing are described in detail. The electric system developed includes a hermetically sealed motor and plumbing similar to that of a household system and decoupled compressor speed from engine speed
