STEPPING MOTOR Russian patent published in 2016 - IPC H02K37/08 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical machines, namely to step motors with discrete rotation, and can be used as an actuating motor, for example, in systems without the angle sensor. Stepping motor comprises housing 1 and end shields 2, 3, on which magnetic cores 4, 5 are mounted. Magnetic core 4 carries wedge-shaped teeth 6 with coils 7. Stator discs 8 are installed on bushing 9 of the stator, and rotor drives 10 - on rotor bushing 11 fixed on shaft 12 supported by bearings 13, 14. Stator discs have alternating ferromagnetic and nonmagnetic elements, rotor discs are made from magnetically hard materials with axially-magnetized sectors of alternating polarity. Ferromagnetic elements of the stator discs form six groups, ferromagnetic elements of which are shifted relative to the magnetized sectors by one third of the tooth step.

EFFECT: technical result is the electric motor design supporting large rotation speed and reliable operation onto a movable base.
