COMMUTATORLESS ELECTRICAL MACHINE Russian patent published in 2015 - IPC H02P9/14 H02P9/30 H02K19/28 H02P6/16 

FIELD: electricity.

SUBSTANCE: commutatorless electrical machine comprises a frame with mounted stator with magnet poles, rotor with winding laid in its slots, rotor position encoder (RPE) and electronic commutator. RPE and electronic commutator are intercoupled by optocoupler consisting of photo sensors and light-emitting diodes. The same elements of optocouplers are coupled by two elements opposed to each other to ends of each section in the rotor winding. Two response elements of optocouplers are placed in normal neutral plane in regard to magnetic poles of the stator and coupled in series into the electronic commutator placed in the machine frame so that they can ensure matched position with elements of optocoupler placed in rotor slots when the rotor is rotated.

EFFECT: reduced electric noise level of electrical machine.
