CONTACTLESS DC ELECTRIC MOTOR Russian patent published in 2009 - IPC H02P6/14 H02P6/16 H02K29/06 

FIELD: electricity.

SUBSTANCE: invention is related to the field of electric engineering and may be used in systems of converting equipment, for instance in DC electric fans. In contactless DC electric motor, comprising rotor permanent magnet, which is connected to three detectors of rotor position on Hall elements by flow of induction, three stator windings, the first leads of which are connected to appropriate outlets of transistor amplifiers, and the second leads are combined and connected to pole of power supply source, logical converter, outlets of rotor position detectors are connected to inlets of logical converter, outlets of which via appropriate inverters are connected to inlets of transistor amplifiers. Transistor amplifier may be arranged on the basis of single bipolar and single field transistors, or on the basis of two bipolar and single field transistors, or on the basis of single field transistor.

EFFECT: higher reliability.
