ELECTRIC DRIVE Russian patent published in 2016 - IPC H02P3/22 H02P25/24 H02K17/00

Abstract RU 2586630 C1

FIELD: electricity.

SUBSTANCE: invention relates to alternating current drive with the mode of dynamic braking of asynchronous motor. In case of mechanical brake failure during emergency shutdown electric brake is used - electric drive changes into controlled dynamic braking mode. Technical result is creation of simultaneous mechanical and electric brake operating mode in emergency modes, including power potage.

EFFECT: use of accumulator in the mode of controlled dynamic braking increases retardation, reduces braking path and increases intermaintenance period for brake blocks and efficiency of hoisting unit.
