DESIGN OF ELECTRIC MOTOR Russian patent published in 2020 - IPC H02K33/18 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment. Electric motor comprises multiple opposite groups of magnets, at least one coil assembly and switching circuit upon detection. Each group of magnets includes at least one magnet, poles of which are located perpendicular to direction of movement of this magnet. Magnets in each group of magnets are laid on each other and have poles of different polarity on each side. Poles of opposite magnets in adjacent groups of magnets have the same polarity. Coil assembly is located between adjacent groups of magnets and is parallel along axis alignment direction between opposite poles of opposite magnets. Each coil assembly includes a magnetising device wrapped by winding. Yokes extend from two ends of the magnetising device in opposite directions and the yoke centres are spaced from each other by a certain distance. Positive and negative power supply is switched over by switching circuit when negative or positive detector is detected. Front yoke and the rear yoke extend at an angle greater than the straight line relative to the magnetising device in order to effectively increase the distance.

EFFECT: technical result is higher efficiency of operation.
