Abstract

PURPOSE:To facilitate damping of a DC motor with a higher voltage and greater capacity and with an easier maintenance, by changing the polarity of a field coil at the time of damping, generating an armature voltage with a reverse polarity to that employed at the time of driving and applying a dynamic braking through a diode. CONSTITUTION:At the time of damping, with opening of a switch 3 and simultaneous polarity change-over by a field change-over switch 5, the polarity of field current If is changed over in the direction of the dashed line as illustrated. By such an operation a voltage with reverse polarity to the illustration is applied to terminals A, B of an armature coil 1a so that a diode 6 is forward-biased and switched on. Therefore a circuit connecting the terminal B, damping resistor 4, diode 6 and the terminal A is formed so that a dynamic braking current flows to the armature coil 1a of a DC motor 1 and the revolving energies of the DC motor 1 are consumed by the damping resistor 4 in the form of he heat energies and a dynamic braking is applied to the DC motor 1.
