DC ELECTRIC DRIVE Russian patent published in 1995 - IPC

Abstract RU 2050686 C1

FIELD: electric drives. SUBSTANCE: evaluation of operation of electric drive is done during some period of time at all the current range, which excesses over nominal one. Electric engine is de-energized when admissible modes of operation is observed, which are described in technical conditions manual. Current restricting circuit has integrating chain, three Schmitt flip-flop with different threshold of operations, three amplitude limiters, and two adders. EFFECT: improved precision of protection of electric engine from current overload. 2 dwg
