Abstract

PURPOSE:To make a device compacter, by feeding an armature coil with a starting current at the time of starting through a resistor and a directional element connected in parallel and reversing the polarity of the field coil at the time of damping and letting a damping current consumed by the resistor thus created. CONSTITUTION:At the time of starting, a field coil 1b is fed with a field current If in the direction of the full line, while a starting current is supplied from a starting electric source 7 through a diode 61 and a resistor 4, and after a fixed duration of time a DC power source 2 revolves a DC motor 1 at a set value with a switch 3 applied. Thus the starting is completed. Then at the time of damping, when a field current If in the direction of the direction of the dashed line is fed with the switch 3 open, the reverse voltage against the polarity shown in the illustration is created to an armature coil 1a resulting in a flow of a damping current through a diode 62 and the resistor 4, and the current is consumed by the resistor 4 in the form of heat energies. Thus with one resistor acting as a starting/damping resistor, a compacter device can be obtained.
