Electrical machine for vehicles, comprises rotor and stator wound with two groups of separately supplied and electronically controlled coils, each group being sufficient to operate the machine

摘要

An electrical machine (10) has a rotor and a stator (11). The stator comprises groups of coils (41,42,43) and (45,46,47) which are independantly fed from supply rings (16,18). The groups of coils are electronically controlled and work together in normal operation. Under stator fault conditions one set of windings will provide satisfactory operation An Independent claim is made for specialised and utility vehicles which use the electrical machine
