Sep 18, 2018· How to Reverse the Direction of a Single Phase AC Motor. The direction of rotation of an AC motor depends on the magnetic polarity of the start winding. Reversing the polarity of the "Start" winding, in relationship to the "Run" winding, reverses the direction of rotation of all single-phase alternating current (AC) motors.
Verify that it is 220V and that neither wire is the neutral, then mark the white wire with black electrician's tape to signal that it is "hot" too. It's a common thing to switch the polarity of the start windings relative to the run windings to change an AC motor's direction. These are usually yellow and orange wires, and the previous installer may have switched these.
The phases have a phase shift of 120 degress - called electrical phase angle, meanwhile the windings on the motor are also shifted by 120 deg - mechanical angle. In a such way, when the current passes trough windings the rotating magnetic field is formed, which is the sum of all three vectors.
Jul 30, 2013· Hot weather always brings on a lot of condenser fan motor replacements. Although it is not too difficult to change a condenser fan motor, it is still possible to do it incorrectly. Of course you need a motor that operates at the same voltage, phase, and frequency of the original motor and it should also be the same horsepower.

Jul 24, 2011· motor is 460, single phase. The tech today tried reversing the start and run wires on the capacitor with no change in rotation. He once again moved the wires to another fan and this time, the problem did NOT move with the wires. I am beginning to think there is a gremlin in the machine.
Sep 24, 2013· I am just explaining a simple condenser wiring diagram and hooking up wiring. Jones Air Conditioning & Electric .jonesairconditioning . How to Replace a Condensor Fan Motor …
Manually-reversible Electric Motor Run Direction. By swapping wire connections on some electric motors it is possible to change or reverse the motor direction. Typically purple and yellow wires or wire pairs permit this change. Purple to purple = rotate clockwise. Purple to purple = rotate clockwise; Purple to yellow = rotate counter-clockwise
Alternating current motors are either induction start-induction run, capacitor start-induction run, or capacitor start-capacitor run motors. AC motors may be single voltage or dual voltage motors with one or two run windings respectively. The run .
Feb 06, 2013· .supercoolsliderule-- This video tutorial demonstrates how to simply reverse the rotation of a reversible motor. Changing the rotation of a reversible motor is simple using these step-by .
Sep 25, 2018· A condenser fan motor is responsible for pulling air out of a unit pulling it out past the condenser, much like a fan and radiator in a car or truck. During the summer when it is hot it will blow the heat away from the condenser through its fins cooling down the refrigerant that flows inside.
To change the direction of a three phase motor, switch any two wires of the three phase feed, and the motor will rotate in the opposite direction. How do you change the rotation direction of the .
Sep 08, 2007· Was the fan mfd on the dual capacitor that was already there the same as what the new motor called for? It seems like when ever I replace a condenser fan motor the new motor calls for a different micro farad then the orginal motor. So I generally install a new cap for just the fan motor and wire it up like you did today.
Fan motor ran one day and died. Took it back for a replacement and this unit has the wiring for direction of rotation matching diagram. Unit has run fine now for two weeks. Did not appreciate having to do the job twice thoughThe Trane is not an easy unit to change the condenser fan motor …
If the condenser fan runs when the starter bar is pressed, everything was hooked up OK. Comment: Finally, check the rotation of the fan motor facing the air discharge side of the grill. For the Model RPKA 035JAZ, fan blade rotation is counter-clockwise.
Jun 03, 2011· The condenser fan is rotating the wrong way. It sucks air from the top and blows down. Also the evaporator fan does not seem to be moving the air inside the house as it should. The compressor stopped working today and a HVAC man installed a new capacitor. He said that the unit must have the wrong fan.
Jul 30, 2013· After installing the motor and fan, turn the unit on and then off again to see which way the blade is turning. If it is turning in the wrong direction, change the rotation leads on the motor. Changing the power leads will have no effect. Once you establish that the fan is turning in the correct direction, operate the unit and check the motor amp draw.
The black wire (noted in the wiring diagram) will likely be terminated on a control board. This control board is the defrost control board. It also controls the condenser fan motor in a heat pump. When a heat pump goes into the defrost cycle the condenser fan motor for the heat pump will shut down.
