Abstract
A drive device for a weaving machine has a motor control unit connected to an asynchronous motor. An electric supply network supplies the motor control unit with electric power which the motor control unit converts to have a substantially higher frequency. This higher frequency power is then supplied to the asynchronous motor causing the motor to operate at a high r.p.m. A speed reducing unit is connected between the motor and a drive shaft of the weaving machine. The speed reducing unit reduces the r.p.m. of the motor and the motor drives the weaving machine via the drive shaft at the r.p.m. of the weaving machine.
