Japanese Patent JPS4837620
Kind Code:
A
Abstract:
A system has a multi-phase motor which includes a rotatable shaft and a stator comprising a multi-phase winding arranged in a star configuration. The rotatable shaft rotates either clockwise or counterclockwise in accordance with a rotating magnetic field generated by energizing the windings in prescribed sequences. A programmer device provides signals for controlling the sequence of energizing the windings. The programmer includes a plurality of bistable devices arranged to form a register having twice as many states as the stator has windings. The register provides the signals for controlling the energization of the windings and also provides signals to a circuit for detecting the direction in which the shaft is being controlled to rotate.
