STEPPING MOTOR Russian patent published in 2009 - IPC H02K37/00 H02K16/02 H02P8/42 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electrical engineering and is to find wide application in robotic engineering and automation systems intended for indexing regulation. The stepping motor 1 contains a stator 2 with teeth 3 and 4, positioned on the stator inner and outer bores, and slots 5 and 6, positioned between them. The slots 5 and 6 contain the winding 7 phase coils. The rotor consists of an electrically conductive part 8 and a magnetically conductive part 9 mounted onto the shaft 10. The rotor electrically conductive part has a diametrical groove 11 arranged all along the rotor active length and filled with an insulation material. On the stator outer bore teeth 4 there are rollers 12 mounted the additional rotor electrically conductive part 13 relies on that is represented by a cylinder with a diametrical groove 14 arranged all along the additional rotor active length and filled with an insulation material. On top of the electrically conductive part 13 the additional rotor magnetically conductive part 15 is mounted. To the voltage source there are five phase winding coil connected to form an arc-shaped assembly; the sequential orders of phases before and after the assembly middle are mutually reverse. To commence rotor stepping one disconnects the last coil of the assembly. To discontinue stepping one simultaneously disconnects the first coil of the assembly and connects the phase coil that follows the last coil of the original assembly.

EFFECT: provision for independent control of two rotors.
