Abstract (en)
[origin: EP0424280A1] The coil (10) of the pulse motor is supplied by a d.c. voltage (V1) and arranged in series with a transistor (T) across the terminals of the supply voltage (V1). The transistor (T) is controlled by the output signal (A) from a chopper (20) slaved to the current traversing the coil in such a way as to permit correct operation of the control circuit for extended ranges of supply voltage. <IMAGE>
