PERMANENT MAGNET MOTOR Russian patent published in 2009 - IPC H02K21/14 H02K1/27 B62D5/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, particularly to electrical machines and can be used as a motor in steering wheel boosters of automobiles and low and medium power electric generators. To achieve this outcome, the proposed permanent magnet motor consists of a cylindrical ferromagnetic external rotor, comprising a shaft, a nonmagnetic disc on the shaft and a magnetically conductive cylinder, on the inner surface of which permanent magnets are placed parallel the axis of the rotor. The said motor also has a cylindrical inner stator, placed in line with the rotor. According to this invention, in the magnetic system of the rotor, magnets on the length of each pole are divided into two parts and displaced from each other around the rotor by an angle Δα/2, where Δα=360°/n, where n is the pulse number of magnetic flux in one cycle of the rotor.

EFFECT: easier control of the motor through reduction of tooth ripples of electromagnetic torque.
