ELECTRIC MOTOR Russian patent published in 2006 - IPC H02K23/54 H02K23/04 

FIELD: electrical engineering; permanent-magnet commutator motors.

SUBSTANCE: proposed motor has stator 1 and disk-type rotor 2. The latter is provided with commutator sleeve 11 specifically disposed on its supporting bush 12 and used to mount rotor 2 on shaft 10 of stator 1. Disposed on commutator sleeve 11 are commutator segments 13 that mount insulating disk 9 of rotor 2 carrying windings 14. Working surface of each commutator bar 13 engageable with brushes 7 is disposed on one end of fixation area 15 of rotor disk 9; mounted on other end of this area are radially bent-out leads 16 of commutator bars 13 electrically connected to leads 17, 18 of rotor winding 14. Radially bent-out leads 16 of commutator bars 13 are disposed in area of cylindrical axial depression 19 of rotor disk 9 communicating with through holes 20 of rotor disk 9 in direction radial to geometric axis of commutator sleeve 11. Rotor windings 14 are placed in holes 2 of disk 9. At least one lead 17 of each winding 14 is passed through slit 24 from through hole 20 of disk 9 to axial depression 19 of rotor disk 9. One of leads 18 of each rotor winding 14 may be also disposed on coil surface of winding 14 and enter axial depression 19 of rotor disk 9.

EFFECT: simplified design and enhanced operating reliability of motor.
