Electrically driven vehicle air conditioning system has compressor driven directly without gearing by electronically commutated, permanently stimulated brushless synchronous motor

摘要

The system has a compressor of lifting cylinder, vane cell or spiral construction (scroll compressor), driven directly without gearing by an electronically commutated, permanently stimulated brushless synchronous motor and commutation electronics supplied with direct current. The drive current is drawn from the on-board electrical system or from the a.c. supply via a rectifier.
