Regulating and control device for drive motor in stitching equipment controls motor depending on rate of rotation and number of revolutions from accurately defined starting point

摘要

The device has a microprocessor (22) and a sensor (23) that detects the rate of rotation and the number of revolutions of a driven shaft (9) from an accurately defined starting point. The information is analyzed by the microprocessor, which produces a regulation and control signal that regulates the current to the motor (2) and hence the rate of revolution of the driven shaft.
