Japanese Patent JP2006025486
Kind Code:
A
Abstract:
To provide an electric electric machine which can reduce cogging torque and can adjust the waveform of an induced voltage, even if a plurality of stators and rotors are arranged.
In the electric electric machine 1 which has rotors each having a rotor core and a permanent magnet and stators each having a stator core and a stator winding wound to the stator core and whose rotor is retained rotatably, having an air gap between the rotor and the stator, and where the rotors 11-1 and 11-2 and the stators 21-1, 21-2, and 21-3 are arranged in a plurality of numbers, a plurality of pieces of stator windings are different winding systems, for example, a combination of a concentrated winding and a toroidal winding.
