Abstract :
A prototype machine of a Switched Reluctance Motor (SRM) having competitive torque and efficiency as well as compactness with respect to an IPMSM in a HEV (Toyota Prius 2003) has been investigated. A torque of 400Nm is set as a target with an outer diameter of 269mm with an axial length of 156mm including coil end length. In addition 50kW field weakening capability must be competitive to the IPM. The highest efficiency of 95% is also aimed. Stator and rotor structures and iron material are investigated. Test machines are built. Static and light load tests are carried out.
