BRUSHLESS DC MOTOR WITH BRAKING AT DEAD STATE Russian patent published in 2014 - IPC H02K1/27 

Abstract RU 2521958 C2

FIELD: engines and pumps.

SUBSTANCE: invention relates to electrical engineering. Proposed motor comprises stator (2), rotor barrel (30) spinning thereabout and provided with several poles (N, S) of permanent magnets and plate (4) connected with stator (2). Said plate creates the locking moment and is furnished with several pole pieces (41) to create said locking moment to lock rotor revolving barrel (30). Said pole pieces (41) are locked between every two adjacent poles (N, S) to produce a magnetic closure. Said plate (4) is arranged, in fact, outside the stator (2) rotating field.

EFFECT: braking at dead state.
