ABSTRACT:
A drive system for a group of brushless A.C. motors (15) which have mutually different working characteristics, for example mutually different voltages or frequencies, and which are arranged to be supplied with electric energy from a static converter (4). The system is characterized in that all motors (15) are arranged to be connected electrically, one at a time, to one and the same converter, and in that an identifying means (10, 13) which is individual to each motor is arranged to be connected to a control input (8, 9) on the converter in order to regulate the converter so that it generates electric energy with the necessary supply parameters to the motor. The invention also covers a hand-tool to be used in the system.
