Abstract:
PCT No. PCT/EP87/00494 Sec. 371 Date Apr. 29, 1988 Sec. 102(e) Date Apr. 29, 1988 PCT Filed Sep. 2, 1987 PCT Pub. No. WO88/01807 PCT Pub. Date Mar. 10, 1988.A circuit arrangement for electronically commutating a multi-phase direct-current motor, in which a predetermined number of markers are distributed around the circumference of the rotor. A sensor detects the markers and generates corresponding commutating pulses to activate the phase windings of the motor. The commutating pulses advance a counter which has a plurality of outputs. These outputs control switches that connect the phase windings alternately to an operating voltage and to a reference voltage. The counter resets itself to zero after receiving a predetermined number of commutating pulses that is a whole-number divisor of the number of markers. A special marker is provided for resetting the counter from the outside, so that the stator applies a torque to the rotor which is always optimum and phase displacement is prevented.
