Abstract
PURPOSE: To make a drive period longer than usual in the start and stop of a coil current by connecting a series circuit, composed of an auxiliary capacitor and switch, in parallel to a resonance capacitor in a resonant type revolving magnetic field driver.
CONSTITUTION: To resonance capacitor 2 of the resonating circuit consisting of driving coil 1, resonance capacitor 2, charge supplying the 1st switch 3, and ON- OFF switch 4 for coil current I0, the series circuit of auxiliary capacitor 5 and the 3rd switch 6 is attached in parallel. Before the start, the 1st switch is operated upward and at the same time, the 3rd switch is tilted to the right to charge initially capacitors 2 and 5. Next, the 2nd switch 4 is operated upward in half the initial period of coil current I0 and the 3rd switch 6 is tilted to the left to elongate the period of half the period of current I0. At the time of the stop, the 2nd switch 4 is operated upward and the 3rd switch 6 is tilted to the left to prolong the driving period.
