US 6,713,889 B2 · Motor-generator system for a motor vehicle with hybrid traction drive

Abstract

A motor-generator system of a hybrid drive with an internal combustion engine (ICE) and an electric machine (EM) connected to an energy storage device (BA) via a converter device (CD). The motor-generator system can be used in addition to supply external power consumers (PC) in isolated operation, with little incremental complexity. For this purpose, the electric machine (EM) includes, in addition to a first stator winding (W1) for traction operation, a second stator winding (W2) for isolated generator operation. The second stator winding (W2) is advantageously coupled in transformer-fashion to the first stator winding (W1) and can thus be supplied with magnetizing current from the energy storage device (BA) via the converter device (CD).
