REVERSIBLE ROTATION CAPACITOR MOTOR

摘要

PURPOSE:To readily operate reversely by controlling a firing angle of a triac connected in series with an operating capacitor to reversibly operating a capacitor motor. CONSTITUTION:A triac 5 is fired by the firing angle of the first mode delayed at the current phase of an auxiliary winding 2 from the current phase of a main winding 1 at starting time to be reversely rotated. When the prescribed time is elapsed, it is normally rotated by firing by the firing angle of the second mode that the current phase of the winding 2 is advanced from that of the winding 1 by a signal of a timer contained in a triac controller 6. Thus, a reversible capacitor motor which inexpensively has excellent reliability can be obtained.
