D. c. motor and power supply therefor

Claim 1

A network including a D.C. motor and a transformerless voltage reducing power supply for operating the motor, the network adapted to be connected across an A.C. source of power having an A.C. output voltage with an effective output voltage level, and the network comprising: a. a series circuit branch including a capacitor and first and second rectifying devices and the D.C. motor electrically connected in series with one another, the rectifying devices being connected in the same conductive direction, the D.C. motor having a D.C. operating voltage level which is less than the effective voltage level of the source output voltage and not having another capacitor connected thereacross, said series circuit branch being connected across the source of power when the network is connected there-across, whereby the source charges the capacitor and operates the motor during alternate half cycles of the source output voltage, and b. switching means electrically connected to the series circuit branch and adapted to switch the charged capacitor into a closed loop during the other half cycles of the source output voltage, said closed loop including a third rectifying device and said charged capacitor and motor and wherein the charged capacitor is electrically connected in parallel with the motor, whereby said charged capacitor discharges through the motor to operate the motor during said other half cycles of the source output voltage.
