ELECTRIC MOTOR Russian patent published in 2015 - IPC H02K33/00 H01F7/18 H02M7/48 

FIELD: electricity.

SUBSTANCE: invention is referred to electromechanics and may be used for conversion of electric energy into mechanic energy in step motors, electromagnetic throwers, electromagnetic rock drills, presses, stamping equipment, etc. The electric motor comprises magnet cores in the primary part 1 with poles 2 and windings 3 and secondary part 4 with poles 5 divided by non-magnet operating gap 6, position sensor for setoff of poles of the secondary part in regard to poles of the primary part 7, neutral position sensor for poles of the primary and secondary parts 8, intermediate position sensor for poles 9, direct-current supply source 11, rectifier bridge 12, auxiliary controlled valve 13, energy storage capacitor 14, auxiliary non-controlled valve 15 and the second controlled valve 16. In the above electric motor magnetic energy is converted into mechanic one at permanent flux linkage and magnetic energy remaining in neutral position of the secondary part is converted into electric energy and used in the next operating cycle of the motor.

EFFECT: increase of operational reliability for the motor.
