Patent Images
1. A three-wire reversing system comprising:
- a capacitive element;
a permanent magnet, reversible, brush-type, direct current motor electrically connected to the capacitive element, said motor having first and second terminals;
a first diode having an anode connected to a first switch lead for clockwise rotation of the motor, said first diode being connected to the first terminal of the motor;
a second diode having a cathode connected to a second switch lead for counterclockwise rotation of the motor, said second diode being connected to the first terminal of the motor;
a common lead connected to the second terminal of the motor; and
an alternating current input voltage source electrically connected to the common lead and selectively connected to one of the first switch lead and the second switch lead.

Abstract
A three-wire reversing system for a permanent magnet, reversible, brush-type, direct current (DC) motor has a three-wire alternating current (AC) input voltage source which supplies electrical current to at least one capacitive element. This capacitive element and the DC motor replace a permanent split capacitor (PSC) and an AC motor in a prior art three-wire reversing system.
