    摘要： A magnet carrier assembly for holding and carrying a high-energy-product permanent magnet is arranged for releasable attachment to a rotor of an axial disc or drum type rotor in an electric machine. The permanent magnet placed in a container which then receives a cover. The magnet carrier assembly includes a mounting flange at one end and a locating and mounting tab at an opposite end for attaching the assembly to the rotor. In certain applications, the rotor has recesses which have a size and shape complementary to the size and shape of the magnet carrier assembly. The recesses are circumaxially located around the radial periphery of the rotor at the poles of the rotor. In other embodiments, the magnet carrier assembly includes a key which is received in a mating groove in a rotor surface and is used to transfer to the rotor the electromagnetic shear force developed by the high-energy-product permanent magnet. The present magnet carrier assembly can be used with both axial field disc or radial field drum rotors. The present invention also contemplates a method and apparatus for removing and installing magnet carrier assemblies in electric machines.

    摘要： An input control current command signal (52) is modified in accordance with a number of compensation factors stored in a memory and corresponding to each of a number of angular shaft positions to provide a control signal to cause an inverter (84) to drive each of the number of phases of a permanent magnet axial-field motor (88) to cause the motor to produce a ripple-free torque output. The compensation values stored in the memory are identified and determined in accordance with the source of the torque ripple such as vibration, load operation, noise and variations within the motor construction.
