Electric drive consisting of electromotor and generator - uses power supplied by accumulator essentially consisting of inductances isolated from associated mains supply after activation

摘要

The accumulator is fed by the generator of the drive after the isolation from the mains. The motor fed by the accumulator (4) also the generator feeding the accumulator, which is coupled to the generator, are galvanically connected across a current output line. It is connected across the connection terminals in the manner of a long induction loop with a large conductor cross- section. The accumulator at its input (14) is galvanically connected to the generator of the electric drive. The electric drive consists of two asynchronous motors (7,8) connected in series. The motors have different outputs and r.p.m.s. The asynchronous motor (8) having the greater output and the higher r.p.m. has a coiled conductor (9) consisting of one turn and a winding (10) connected with this in series. The output (11) of the winding (10) is essentially the line (13) feeding the motor of the electric drive. ADVANTAGE - Drive motor is supplied with predominantly unrestricted power. Voltage from accumulator compared with supplied voltage is relatively large, to hold and to ensure that voltage is maintained in accumulator over relatively long time.
