Abstract

PURPOSE: To positively generate initial high tension even when a power switch repeatedly operates for a short time, and to ensure the excellent response of an electromagnetic brake.
CONSTITUTION: When a power switch 5 is in ON at time To, a motor terminal voltage detecting circuit 11 is operated, and whether or not the set value is not less than Epp is discrminated. Consequently, an operation stop circuit 12 does not work, a brake voltage control circuit 13 works, a high tension generating reset circuit 14 does not work, and a high tension generating circuit 15 works only during T1 from a time To decided by the time constant, thus turning a motor 3. An electromagnetic brake can be operated by setting brake voltage EB to O even if voltage by the revolution of the motor 3 and residual magnetic flux is generated after the power switch 5 is in OFF, thus allowing the improvement of response.
