The torque was measured with a torque transducer mounted on the shaft of the machine. See Appendix D for pictures of the measurement setup and [20] for a complete description of the laboratory setup. We now will follow the same approach as for induction machines, with the surface-mounted permanent-magnet synchronous motor (SMPM-SM), establishing first the electrical equations. Permanent magnet exited synchronous machines always show three signicant portions of their losses: Iron lossesIn particular, surface mounted magnets are directly exposed to asynchronous components of the air-gap eld caused by either higher harmonic waves or higher time harmonics.
