Abstract
A circuit for driving a solenoid clutch in which an input side rotating member and an output side rotating member are separated by a gap at the completely disengaged state comprises a voltage generator capable of generating at least the rated voltage of the solenoid clutch and an initial exciting voltage by which a minimum attracting force for the engagement is provided to an electromagnet of the clutch, and a controller for controlling the supply of the output voltage from the voltage generator in response to a command to engage the solenoid clutch in such a way that the rated voltage is applied to the solenoid clutch after at least the initial exciting voltage is applied to the solenoid clutch for a predetermined period. The application of the initial exciting voltage makes the electromagnet to produce a week attracting force, so that the transmitted torque of the solenoid clutch is small. In this state, the solenoid clutch is completely engaged without shock by the application of the rated voltage.
