How to conect 3 phase motor 9 yellow wires from t1 to t9

One needs to know what the voltage and phase(1 or 3) the unit is and what the power supply is.

Having 9 wires means it is a 3 phase motor.
For 220 to 240 Volts - L1, T1 and T7 go together. L2, T2 and T8 go together. L3, T3 and T9 go together. T4, T5 and T6 go together.

For 440 to 480 Volts - L1 and T1 go together. L2 and T2 go together. L3 and T3 go together. T4 and T7 go together. T5 and T8 go together. T6 and T9 go together.

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.

The terminals you listed are correct.
T4 -T7 mated
T5 -T8 mated
T6 -T9 mated
10, 11, 12 combined connection

L1, L2, & L3 = output / line leads

However you should have 277 VAC line to ground and 480 VAC Line to line (Across any 2 phases)

So terminals 1, 2 or 3 to ground should be 277 VAC (L1 L2 or L3)
1-2 or 1-3 = 480 VAC
any combination of
1 , 2, or 3 to each other = 480 VAC

As a "generator man" with 19 solutions one being "You might have to sting it" you should know this and be able to use the diagram on the power head to get your desired voltages unless the wiring data plate is missing. I have had to dial in voltage regulators when switching between 240 and 480 to prevent automatic shut downs from over / under voltage.

Assuming you have a standard dual-voltage single-phase motor, your wire colors should be:

T1 - Blue
T2 - White
T3 - Orange
T4 - Yellow
T5 - Black
T8 - Red

For 220V wiring, you want:

Line 1 (to Black wire from switch):
Blue
Black

Line 2 (to White wire from switch):
Yellow

Tied together with a wire tie:
Red
Orange
White

This should make it so the shaft spins counter-clockwise. If you need it to spin the other direction, switch the red and black wire from the motor.

Assuming that the motor has 9 leads and the wire numbers are still on the wires, for 240 volt 3 phase connections:

Connect T1, T6, and T7 together with L1 (A phase)

Connect T2, T4, and T8 together with L2 (B phase)

Connect T3, T5, and T9 together with L3 (C phase)

If you're not sure which of the incoming wires from the supply are L1, L2, and L3, just pick one. If the rotation is wrong just swap any 2 (TWO) phase wires.

Connect t4,t5,t6 together. Connect t1,t7 together for line 1. Connect t2,t8 together for line 2. Connect t3,t9 for line 3.

i have a doerr electric motor, lr22132 single phase 220v, 3/4 HP with wires t2, t3, t4, t5, t6, t7, t8 and earth, how do i hook up, any help would be great,

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.

the neutral or white is not used. if the fourth wire is a ground then it goes to the motor frame. if it is a dual voltage motor then here is the wiring: for 240 volt 3 phase connect 4-5-6 together and tape, 3-9 goes on L1, 2-8 together goes on L2, 1-7 together goes on L3. To reverse direction swap any two line wires. For 480 volts 3 phase: L1 goes on T1, L2 goes on T2, L3 goes on T3. Connect together T6-T9 and tape, connect T5-T8 and tape, connect T4-T7 and tape. again to reverse direction swap two line wires.
