PURPOSE:To manufacture the energy conservation type clutch motor in compact by a method wherein the applying voltage to the motor is controlled by a thrystor in accordance with the load, and the controlling part is built-in in the cover of motor on the opposite side of a flywheel. CONSTITUTION:A bi-directional three terminals thyristor 24 or an antiparallel thyristor is connected in series with the clutch motor 23 to control the phase, and when the clutch motor 23 is in the no-load condition, the applying voltage is reduced, and at the loading time, the whole voltage is applied thereon. The cover 26 is equipped at the end part of the clutch motor 23 on the opposite side to the flywheel 6, the thyristor device 24 and a control board 29 thereof are built-in in the cover, and a ventilating opening 27 is provided at the part being the lower side when the clutch motor 23 is equipped. Accordingly, the energy conservation can be achieved, and the motor can be manufactured in compact at low cost. |
