Abstract

The optimised system consists of an electrical motor (5) coupled to a photovoltaic effect generator (16) in which the armature of the motor is directly fed by the generator. A servo circuit is connected to the motor terminals. The circuit includes a differential amplifier (10) which receive a voltage proportional to the motors armature reaction and a reference voltage. The output of the differential amplifier (10) feeds an amplifier (11) mounted in series with motor field winding (7). The servo circuit maintains the motor armature reaction force constant. One of the differential amplifiers inputs (U) is connected to the tachyometer (4, 6) on the motor shaft. The other input (Uo) is connected to a voltage divider (8, 9).
