摘要： A reluctance motor having a rotor and a stator that has a wound core, around which a stator coil is wound and which is open on one side and has legs, said legs being arranged around the periphery and forming spaced-apart pairs of legs. Multiple rotor teeth which are distributed around the periphery and periodically establish a magnetic flux between the legs radially engage between the legs. In order to positively change the characteristic curve of the magnetic flux of the legs and teeth, the teeth continuously form an area overlap with the legs in the direction of rotation of the rotor in accordance with the angle of rotation.

摘要： A rotating electric machine includes a stator and a rotor. The tip of a salient pole portion of the rotor is bilaterally asymmetrically provided with a cut. The effect of the cut reduces torque ripple during a regenerative running mode. The regenerative running mode is not performed during low speed running but is often performed during high speed running and the driver is more sensitive to in the regenerative running mode noise than in a power running mode. As for the regenerative running mode, measures against torque ripple are taken based on the structure of the rotating electric machine. Preferably, as for the power running mode which bothers the driver about noise during very low speed running, a controller allows a compensation current to be fed to take measures against torque ripple. A compact and high power vehicle drive system with torque ripple reduced and a vehicle incorporating the vehicle drive system can be provided.

摘要： A switched reluctance machine has a stator which has an array of alternate wide and narrow poles around its inner circumference. Coils are wound around the wide poles only. The rotor includes segments of soft magnetic material carried on a non-magnetic core. The segments are so proportioned at the air gap that the flux produced by one stator coil passes through two or more segments and returns through the adjacent narrow poles. The machine is capable of producing a high output.

摘要： A rotor of a flux barrier type synchronous reluctance motor comprises: a rotation shaft; a rotor core formed as a plurality of steel plates are laminated to one another, the steel plate having a shaft hole for inserting the rotation shaft, a plurality of flux barrier groups spaced from one another in a circumferential direction and having a plurality of flux barriers spaced from one another in a radial direction, and a coupling hole penetratingly-formed between the adjacent two flux barrier groups; and a coupling member inserted into the coupling hole and fixing the steel plate. Accordingly, a fabrication cost and an entire weight of the motor are decreased, and a fabrication process is facilitated with a shortened fabrication time. Also, a large coupling intensity is obtained and a magnetic saturation does not occur, thereby preventing a function degradation of the motor.
