ABSTRACT:
Drive mechanism for working machines, especially industrial sewing machines, including a speed-controlled DC motor without a collector, the windings of this motor being supplied by way of a power stage having a full bridge circuit, actuated in dependence on the rotor position of the motor. A safety monitoring circuit responding to overcurrent is associated with the power stage in order to block the full bridge circuit in case of overload. The drive mechanism is furthermore provided with a microprocessor control for the positioning and ancillary functions of the driven working machine.
