A study of an outside-rotor switched reluctance machine for a crankshaft starter-alternator system with additional motor operation is presented. The specifications for this application can be characterized by a nominal generating power of 5 kW and a starting torque of 200 Nm in combination with a 42 V electrical power system. Due to the high starting torque and a small installation area an outside-rotor design for switched reluctance machines is chosen. With a larger air-gap radius than with standard inside-rotor machines the demanded starting torque at a short overall length of the machine can be obtained. The designed machine can be used instead of the standard V -belt alternator to obtain higher electrical power with extra motor performance at the same time. Such a system, which allows a lot of additional features regarding drive performance, is propagated as minimal- or soft-hybrid system.
