PURPOSE:To lessen a shock due to fluctuations in change of rev count of an engine at the time of connecting fly wheels by applying an exciting current corresponding to the acceleration of each rev count of an engine and a fly wheel to an electromagnetic clutch during a set period of time just before the estimated connecting point of time. CONSTITUTION:In an apparatus in which a fly wheel is connected and disconnected to and from an engine rotary shaft through an electromagnetic clutch device to give and receive power, provided is a control circuit 11 for controlling an electromagnetic coil 12 of the electromagnetic clutch device. The control circuit 11 includes rev count detecting circuits 46, 47 for detecting rev count signals S7, S9 of an engine and a fly wheel every fixed time and means 48-50, 58-60 for computing the acceleration of each rev count, and positive and negative directions, and storing and deciding same. The circuit further includes an exciting current control device 56, which is adapted to control to apply an exciting current corresponding to the acceleration of each rev count to the electromagnetic coil 12 during a fixed period of time just before the connecting point of time estimated by a fixed procedure. |
