description High speed machine has become an integral part of today’s technology. High speed machine comes in many forms including induction machine, switched reluctance machine, permanent magnet and claw poles. An aircraft Auxiliary Power Unit is an example of an equipment that makes use of high speed machine. Regardless of its type, one of the few things it has in common is losses. The components that contribute to a machine’s loss includes stator and rotor loss, core loss and windage loss. Because core loss is proportionate to the frequency and speed of the machine, it is therefore important to properly estimate core loss in a high speed machine.
