3 wire ac fan motor wiring diagram. The motor will also have three speed wires and one neutral wire. On a dual run capacitor there are 3 terminals. I ll provide a diagram and explain the wires below. Since most oem motors only have 3 wires and most replacement condenser fan motors have 4 wires this creates a little confusion.

Ray great question. Using the fan manufacturer s wiring diagrams as a guide locate the wires for the three speed switch and the fan s motor. Motor connection diagrams electric motor wire marking connections for specific leeson motor connections go to their website and input the leeson catalog in the review box you will find connection data dimensions name plate data etc. Find the correct wiring connections for your particular motor.

White wire from the condenser fan motor to one side of power on the contactor t1 and jumped to one side of the fan capacitor. The hand drawn diagram in your question shows blue and red reversed. 1 labeled h or herm of the compressor one labeled c or com for the common and 1 labeled f or fan for the fan motor. However it is also possible that the motor was manufactured with wire colors that do not match the manual.

For the ccw rotation wires 1 and 8 are connected together and wires 4 and 5 are connected together. It is possible that is an acceptable means of reversing the rotation of the motor. This is ac power and not a dual capacitor so the terminal side does not matter. For example if the motor is single phase single voltage and you would like it to rotate in a counter clockwise direction the chart shows that input power is connected to l1 and l2.
