Abstract
A drive system for a machine, in particular a weaving machine, is designed in a manner such that controlled electric power is applied to a rotary electric drive motor (2) as a function of particular angular positions of the motor and such that electrical energy applied to the motor is reduced or interrupted during phases of increasing angular speed of the motor. Phases of increasing angular speed are detected by the drive system to determine phases of increasing angular speed. A method for controlling an electrical motor drive system using a switchable reluctance motor to reduce or interrupt electrical energy supplied to the motor based on motor speed increases as a function of motor angular position is also disclosed.
