ABSTRACT:
The bidirectional rotation device comprises a direct current motor connected in series with a capacitor and a reversible switching means. When a direct current voltage is applied to the series-connected combination of direct current motor and capacitor through the switching means in one position, the charged capacitor causes the motor to rotate in one direction for a short period of time; and when the voltage is again applied to the combination in the reversed polarities, the reversely charged capacitor will cause the motor to rotate in the reverse direction.
