    摘要: Aspects of the invention relate to a switched reluctance motor and the reduction of motor torque output ripple by inclusion of flux barriers. The inclusion of flux barriers running parallel to the motor shaft axis located in the appropriate places in either or the rotor and stator can modify the torque profile output of the motor markedly reducing potential vibration problems in a vehicle driveline.

    摘要: The present disclosure relates to an electric drive motor (101; 201) for a vehicle. The electric drive motor (101; 201) has a stator (103) having a plurality of slots (107); and a rotor (102; 202) having a plurality of poles (106; 206). The poles (106; 206) each have at least a first permanent magnet (104; 204) centred on a d-axis of the pole (106; 206); and a plurality of flux barriers (109; 209) for disrupting at least an n-th order torque harmonic of the electric drive motor (101). Proximal to an outer surface of the rotor (102; 202), a first angular period (x11) between first and secondary flux barriers is defined by the equation (xi1=tao/n1), whereby: (xi1) is the first angular period; (tao) is the pole step; and n1 is an order number of a torque harmonic to be disrupted.

    摘要: In one aspect of the invention for which protection is sought there is provided an electric machine comprising a substantially circular rotor and a stator, wherein the stator comprises at least one substantially arcuate segment. Aspects of the invention also relate to a stator segment comprising at least one inter-pole shield disposed between adjacent teeth. Further aspects of the invention also relate to a stator segment having a first shield disposed at a first circumferential end thereof and/or a second shield disposed at a second circumferential end thereof. Aspects of the invention also relate to a stator segment having a radially outwardly directed protuberance.
