 A capacitor ranging from 3 to 25 microfarads is connected in series with the "start" windings and remains in the circuit during the run cycle.[4] The "start" windings and run windings are identical in this motor,[4] and reverse motion can be achieved by reversing the wiring of the 2 windings,[4] with the capacitor connected to the other windings as "start" windings. By changing taps on the running winding but keeping the load constant, the motor can be made to run at different speeds. Also, provided all 6 winding connections are available separately, a 3 phase motor can be converted to a capacitor start and run motor by commoning two of the windings and connecting the third via a capacitor to act as a start winding.  A capacitor ranging from 3 to 25 microfarads is connected in series with the "start" windings and remains in the circuit during the run cycle.[4] The "start" windings and run windings are identical in this motor,[4] and reverse motion can be achieved by reversing the wiring of the 2 windings,[4] with the capacitor connected to the other windings as "start" windings.
