    摘要： A permanent magnet machine includes a stator having a stator core, a plurality of stator teeth and plurality of stator windings coupled to the stator core. The stator is configured to generate a stator magnetic rotating field when the stator windings are excited with an electric current. The stator magnetic rotating field includes both synchronous sub-harmonic and super-harmonic components. The permanent magnet machine also includes a rotor that is disposed within the stator. The rotor includes a rotor core and a plurality of rotor magnets that are coupled to the rotor core. The rotor magnets are further configured to have a predefined orientation profile such that when the stator windings are excited with an electric current, sub-harmonic and super-harmonic magnetic rotating fields are generated in the rotor magnetic field. The stator sub-harmonic and super-harmonic magnetic rotating fields interact with the rotor sub-harmonic and super-harmonic magnetic rotating fields and produce an aiding torque on in the permanent magnet machine.

    摘要： Locking strips secure winding modules to a rotor. The locking strips have paired deep and shallow recesses along a long edge and are disposed in a groove along the rotor. Upon assembly of the winding module, the deep recesses of the locking strips are aligned, enabling the winding supports of the winding module to engage in the deep recesses. The strips are then axially displaced in opposite directions relative to one another to engage portions of the strips within grooves of the winding supports and edges of the shallow recesses to straddle the winding supports. Pins are received in aligned holes of the locking strips in the locked configuration. Consequently, the modular winding is retained against axial and peripheral movement and outward displacement along a parallel face of the rotor shaft.

    摘要： A method is disclosed for fitting a rotor enclosure over at least one assembly of field windings mounted on a rotor core, said method comprising the steps: applying a force to elastically reduce a circumference of the at least one assembly of field windings mounted on the rotor core, where the reduction in circumference is greater than a circumference reduction due to just eliminating clearances between adjacent end-turns of windings; generating a clearance between the field windings and the rotor enclosure due to the application of the force; axially sliding the rotor enclosure over the at least one assembly of field windings while the circumference is reduced, and releasing the force to allow the circumference of the at least one assembly of field windings to expand and cause the enclosure to tightly fit on the at least one assembly of field windings.
