Yes, it is possible to reverse the rotation of the LR63420 Model D motor from CW (clockwise) to CCW (counterclockwise). Here's how to do it:
Turn off the power supply to the motor.
Remove the motor cover to access the motor terminals.
Identify the two wires connected to the start winding of the motor. These wires are usually marked with the letter "S".
Swap the positions of these two wires. For example, if wire A is connected to terminal 1 and wire B is connected to terminal 2, then disconnect wire A from terminal 1 and connect it to terminal 2. Then disconnect wire B from terminal 2 and connect it to terminal 1.
Reinstall the motor cover.
Turn on the power supply and test the motor to see if it is now spinning in the desired CCW direction. If not, repeat steps 3-5, making sure to swap the correct wires.
Note: Reversing the rotation of a motor may affect its performance and should only be attempted if you are experienced with electrical wiring and motor repair.
You need to determine at which voltage you will run this motor. A motor starter mechanically and electrically interlocked for F & R. with 24v transformer, a SS and FR station. This is expensive but sweet, needs room for this equipment. The easy budget is by using a drum switch. The motor nameplate or splice box cover will hand the info on how to connect the motor for either voltage and for CW and CCW rotation. The magnetic motor starter also will include a wiring diagram.
Rewire for ?? High voltage motor wiring is L1-T1, L2-T2, L3-T3, T4-T7, T5-T8, T6-T9. Low voltage is L1-T1-T4, L2-T2-T5, L3-T3-T6. The motor protection overloads will need to be sized accordingly, to the motor's FLA ( full load amps) for the voltage used. The control needs to be looked at also, if there is a control transformer, the transformer needs to be wired or repaced for the new supply power voltage used.
Single phase motor for 230V, connect T4 and T5, to one line. T2, T3, T8 common connected. T1 to other line. Check Rotation, This should be for CCW rotation facing output shaft. Swap T5 and T8 for CW rotation.
The green should be connected to the chassis, it is ground.
There should be a wiring diagram on it to tell you how to do this, but if not:
There may be T-leads on the motor labeled
P1, P2, T3,T4,T5,T8
P1-L1(black wire)
P2-cap/tape don't use.
T2,T3, and T5 wire nut together
T4,T-8 wire nut together with L2(white)
The power leads will be coming from your switch box on the compressor body itself. Don't wire the 220v directly to the motor, you replace the leads where the first motor was connected on the cutoff switch. There will be only 2 leading from the switch to the motor.
motor leads on a three phase are T1, T2, T3, T4, T5, T6, T7, T8, T9. for high voltage [480] L1 to T1, L2 to T2, L3 to T3, connect together and tape - T4-T7, T5-T8, T6-T9. For LOW voltage [240] L1 to T1 & T7 & tape, L2 to T2-T8 & tape, L3 to T3 & T9 & tape. T4-T5-T6 together and tape.
L 1 is power in .L 2 is also power in.line means this is were the power needs to be hooked to . cw / stands for clock wise rotation . ccw stands for counter clock wise rotation.
there is normally a name plate on the inside of the cover that shows high and low voltage connections without that the connections could be a couple different ways. Have a look Im sure its there
