AC ELECTRIC MACHINE FOR VEHICLE

摘要

An AC electric machine for vehicle comprises an AC electric machine body 100 having a rotor 10 provided with a first rotary shaft 12 rotatably supported by a pair of bearings 16 and 17, a rotor core 8 fixed to the first rotary shaft 12, and a field winding 9 wound around the rotor core 8, a stator 3 provided with a stator core 1 opposed to the rotor 10 and a multi-phase stator coil 2 wound around the stator core 1, and a bracket 80 supporting the pair of bearings 16 and 17 and the stator 3, and a rotational position sensor 20 for control having a second rotary shaft 30 coupled with the first rotary shaft 12 via large magnetic reluctance portions 32 and 33, a second rotor 21 fixed to the second rotary shaft 30, and a second stator coil 22a for generating the output voltage because of the rotation of the second rotor 21.
