Abstract

PURPOSE: To provide the subject device wherein at the time of starting a DC motor the starting torque is intensified by the intensification excitation, and an abrupt deviation signal is imparted to a speed adjustor simultaneously with the completion of starting, whereby time from the starting to the speed setting is curtailed.
CONSTITUTION: At the time of starting the motor, a chopper device 9 for field control of the motor 1 is controlled by a phase angle controller 11 to inensify the excitation. The output of a rotational speed detecting generator 5 is supplied as input to a filter amplifier 15 through a speed adjustor 6 and a polarity inverting amplifier 13. Accordingly, the total input of the speed adjustor 6 is maintained substantially at zero. When the starting operation is completed, a contact 12 is opened and the phase angle controller 11 is cut off, and simultaneously, a contact 14 is opened. A speed setting input is supplied to the motor at a time slightly earlier than the opening of the contact 14, and accordingly, the input of the filter amplifier 15 is increased stepwise to the sum of the value of the speed setting input and the speed detected value.
