ELECTRIC MOTOR AND GEAR MOTOR Russian patent published in 2015 - IPC H02K23/04 

FIELD: electricity.

SUBSTANCE: invention relates to electric motors installed, in particular, in vehicles. The electric motor contains a stator, four permanent magnets located on internal side of the stator so that their magnetic poles alternate with each other, an armature comprising a shaft, an armature core fixed on the shaft and having eighteen teeth, a collector fixed on the shaft and fitted with segments isolated from each other, an inductance coil of the armature. The armature is located inside the stator so that it is surrounded with four permanent magnets of the stator. The motor has also common, low-speed and high-speed brushes. The common brush and the low-speed brush are displaced with respect to each other by 90 degrees. The high-speed brush is displaced by 90 or more degrees with respect to common brush and the low-speed brush. The common brush is connected to the cathode or to the anode so that the electric current rotating the armature with low speed, is supplied to the low-speed brush, the electric current rotating the armature with high speed is supplied to the high-speed brush.

EFFECT: decrease of vibration and noise of the electric motor, and also providing of small sizes and high efficiency.
