COLLECTOR ELECTRIC MOTOR Russian patent published in 2010 - IPC H02K23/22 H02K23/02 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electric engineering, namely to collector electric motors (CEM) with compensation winding, and is intended for putting machines and mechanisms in motion in those cases, when deciding factor is provision of potential stability of their collectors to formation of flashovers. Technical result is achieved by means of selecting rational parametres of compensation winding and geometry of geared zone of main poles, and also by means of bevelling their slots.

EFFECT: increased potential stability of CEM to formation of flashovers at collector.
