Abstract

The influences of stator winding resistance and dc bus voltage variations on the efficiency maps of permanent magnet machines for motoring and generating operations are discussed. A large-scale design optimization algorithm is presented in which the efficiency requirements are independently treated for motoring and generating operations over the entire torque-speed plane. The separate treatment of efficiency is especially important in machines with large per-unit stator winding resistances, or in machine-drive systems with unregulated dc bus voltage, as is the case for low-voltage hybrid vehicle systems.
