Title: Keep solenoid driving circuit
Inventor: MATSUMURA NAGANOBU
IPC: H01F7/18
Filed: 2000-05-22
Abstract: PROBLEM TO BE SOLVED: To obtain a small-sized, simple, and energy-saving keep solenoid driving circuit at a low cost by performing the restoration and attraction of a keep solenoid by means of one control circuit by utilizing the charging currents of capacitors although the conventional keep solenoid driving method uses instantaneous currents for driving the keep solenoid and, accordingly, requires control circuits for sending the instantaneous currents for the restoration and attraction, respectively. SOLUTION: In this keep solenoid driving circuit, capacitors C1 and C2 are respectively connected in series with the restoration and attraction coils of the keep solenoid through relay contacts a1-a4. When the contacts al-a4 are turned on, therefore, the charging current of the capacitor C1 flows through the restoration coil and the keep solenoid is restored (a plunger is protruded). When the relay contacts a1-a4 are turned off and contacts b1-b4 are turned on, the charges charged in the capacitor C1 are discharged and charge the other capacitor C2. Consequently, the charging current of the capacitor C2 flows through the attraction coil and the solenoid attracts. Namely, the keep solenoid is restored and caused to attract with the instantaneous currents (charging currents) by turning on/off relays by means of one ON/OFF control signal.
