Abstract
PURPOSE: To effectively erase a residual magnetic flux of an electromagnet, and to always execute a stable damping operation, by providing a circuit for supplying a reverse energizing current to the electromagnet, on an energizing circuit.
CONSTITUTION: When a stop command signal is supplied, a driving IC20 is closed, an energizing transistor (TR)16 is turned on, a DC energizing current from an electric power supply 14 passes through the TR16, is supplied to an electromagnet 12, and a desired damping operation is executed by the electromagnet 12. Subsequently, when the command signal is turned off, the IC20 and the TR16 are turned off, a reverse energizing current is supplied to the electromagnet 12 through resistance groups 30, 32 and 36 from a DC current source 34, and a residual magnetic flux of the electromagnet 12 is erased.
