PROBLEM TO BE SOLVED: To provide a rotary electric machine having a structure hardly influenced by magnetic interference of each of phases and reducing cogging torque to cause torque ripple in order to solve the problem that a coupled core external circumference of a stator magnetic pole causes electric interference on each of the phases and a control constant of a controller to be driven is influenced by the other phases, resulting in less controllability in a conventional technique, and further, to reduce the cogging torque to cause torque ripple in the structure of a rotor. SOLUTION: This rotary electric machine has a profile in which the magnetic poles can be separately disposed. In the electric machine, two magnets 3a, 3b of the rotor are disposed with a phase difference by an electric angle. COPYRIGHT: (C)2009,JPO&INPIT |
