The permanent magnet machine (10) includes a stator assembly (12) and a rotor assembly (14), with a plurality of ferrite permanent magnets (32) disposed within the stator assembly or the rotor assembly to generate a magnetic field that interacts with a stator magnetic field to produce a torque. A controller (22) of the electrical machine is programmed to cause a primary field current to be applied to the stator windings to generate the stator magnetic field, so as to cause the rotor assembly to rotate relative to the stator assembly. The controller (22) is further programmed to cause a secondary current to be applied to the stator windings to selectively generate a secondary magnetic field, the secondary magnetic field inducing eddy currents in at least one of the stator assembly and the rotor assembly to heat the ferrite permanent magnets.

The alternating hybrid excitation assembly comprises an even number of iron cores and a plurality of magnetic isolation layers arranged between the iron cores, wherein the iron cores and the magnetic isolation layers form a closed loop or an open loop, each iron core is provided with one or two notches, permanent magnets are inlaid in the notches of the iron cores, the two magnetic pole faces of each permanent magnet are closely attached to two opposite sides of the notch of the corresponding iron core, and a gap is reserved between one side face of each permanent magnet and the side edge of the notch of the corresponding iron core; and furthermore, the permanent magnets inlaid in the notches of every two adjacent iron cores have opposite magnetic polarity directions, and an excitation coil surrounds the iron cores. According to the alternating hybrid excitation assembly, a permanent magnetic potential and an excitation magnetic potential are superimposed to form an alternating hybrid excitation magnetic field, and thus electromagnetic energy efficiency is improved.

摘要： A fault tolerant virtual elliptical electric motor has at least five coil elements constrained in a stator case. A drive plate is supported by a fulcrum for nutating motion and has at least five core segments each associated with a respective one of the at least five coil elements for attraction upon activation. A control processor provides independent current control to each of the at least five coil elements for activation responsive to a received position command and a received wobble angle input, inducing the at least five coil elements to operate in a pure torque sum configuration upon the drive plate.

摘要： The moldability of the stator of an axial gap type rotating electric machine is improved. The axial gap type rotating electric machine has: a stator comprising core members disposed about a rotating shaft in a ring shape with a predetermined space from adjacent core members, said core members each having a core around which a coil is wound, the number of the turns of the coil being less on the outer perimeter side than on the inner perimeter side, the core members being molded with mold material; and a rotor facing an end surface of the core in the shaft direction through a predetermined gap. The core members comprise: a first core member in which the number of coil winding layers on one side in the shaft direction is larger than the number of winding layers on the other side; and a second core member in which the number of coil winding layers on one side in the shaft direction is less than the number of winding layers on the other side. In the stator, the first and second core members are alternately disposed, with the coil on the side where the number of the winding layers of the first core member is larger and the coil on the side where the number of the winding layers of the second core member is smaller opposed to each other.
