Abstract
In a D.C. motor in which signals generated by an angular position transmitter control the commutation of the current flowing through the stator winding via a selection circuit containing Exclusive OR gates by means of which the polarity of the signals generated by the angular position transmitters can be reversed for the reversal of the direction of rotation, operating modes of 'Operation' and 'Braking' can be specified with only one command input for the Exclusive OR gates using an additional Exclusive OR gate.
