'Drive system with change richter stored tem electric motor and a method for extending of the motor rotational speed range'

摘要

several controlled wechselrichterschaltungen (42, 42), each of which contain several electricity conductive branches, the controlled rectifier (50, 66, 50, 66), and associated kommutierungskondensatoren (70, 78, 70 to 78) are parallel connected and are individually controlled to share e lektrische performance to a load in the form of a wechselstrommotors (49) statements.if a high speed and a low torque is required, less than all wechselrichterschaltungen kept in operation in order to have a sufficient power within the effective wechselrichterschaltung or circuits to maintain an effective wechselric hterkommutierung to ensure.
