ELECTRODYNAMIC BRAKE FOR GENERAL-PURPOSE ELECTRIC MOTOR Russian patent published in 2015 - IPC H02P3/12 B60L7/04 B60L7/06 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering and can be used for general-purpose electric motors in a manual electrical machine equipped with dangerous tools. In an electrodynamic brake for a general-purpose electric motor, an excitation winding is fed from a power grid at operation in a braking mode, and an armature is directly short-circuited. A braking process is performed under control of a programme put into a controller of control electronics, due to which effective braking is achieved at comparatively low wear of brushes.

EFFECT: improving reliability in a braking mode and in a motor mode at availability of dangerous tools.
