Abstract

PURPOSE:To reduce a shock at the time of charging and thereby to prolong mechanical lifetime of the device by controlling the phase of the coil impression voltage by SCR, by making the current flowing to a coil into the charged current by full voltage in the instant of charging, and by attenuating the current gradually and continuously. CONSTITUTION:The coil CC for driving is connected to the DC-output side of a full-wave rectifying circuit SR, while a Triac FLS is connected serially with an operation switch SW to the AC-input side of the circuit SR, and further a gate control circuit GCC for controlling the Triac FLS is composed between two terminals T1 and T2 of the Triac FLS. By this constitution, the current at the time of charging is reduced continuously and thus nearly uniform attracting power can be generated in the driving coil. Thereby the the shock at the time of charging can be reduced and the mechanical lifetime of the device can be prolonged.
