Abstract:
PROBLEM TO BE SOLVED: To disclose a switching device which supplies drive voltage UB for releasing a magnetic holding brake B of an electric motor M, and holding voltage for holding the released holding brake B, that is decreased as compared with the drive voltage, to the holding brake B.SOLUTION: In a switching device, drive voltage UB is supplied by one control device S disposed on an upstream side separately from a motor M and a holding brake B. The switching device has one voltage regulator which is disposed in the inside of the motor M or on the motor M, or disposed in the inside of the holding brake B or on the holding brake B, and is provided so as to adjust voltage decreased after releasing the holding brake B to be one fixed value regardless of the drive voltage UB.SELECTED DRAWING: Figure 1
