BUTT-END MOMENTUM MOTOR Russian patent published in 2005 - IPC

FIELD: electrical engineering, in particular, electric motors and electric drives, concerns fulfillment of but-end momentum motors.

SUBSTANCE: the but-end momentum motor has a butt-end rotor with permanent magnets located on it and two stators arranged on both sides of the rotor. According to the invention, the magnetic core of each stator is made of stacks of plates located in the radial direction, and of hollow cylindrical components of different diameters, each having teeth on the butt-end facing the rotor, the number of the given teeth equals the number of the pairs of the rotor poles. The teeth of the outside and inside cylindrical parts of each stator are shifted in angle through the angular width of the rotor pole, a circular winding of one of the two phases is positioned between the cylindrical magnetic cores, and the teeth of the cylindrical parts of the magnetic cores of different stators are shifter in angle relative to each other by half the angular width of the rotor pole. The stacks of the plates located in the radial direction are fastened on the motor cover.

EFFECT: simplified construction of the motor with a great number of the pairs of poles, at simultaneous enhancement of the adaptability to manufacture, as well as reduced loss of labor consumption and cost of the motor.
