    Do you mean 230 volt? Does it have a nameplate? It should list the voltage as 120/230 volt. Is there a wiring diagram inside the box cover? It should show diagrams for low voltage(120) & high voltage (230). If not, I would advise consulting an electrician.

There should be a wire diagram on the motor tag or under the coverplate. Eric

I need to wire up a baldor 3 phase motor 208-230/480 15hp and dont have the wiring diagram to know what wire is what or where to hook it to?


Hi Casey, I'm an electrician and can help you with this problem.

First, a disclaimer. Without the catalog number of the motor you have, or a wiring diagram for it, no one can tell you how to wire this motor with any certainty. With that said...

Nearly all single speed 3 phase motors have 9 leads (numbered 1 thru 9) and can be wired for either "high" or "low" voltage. Most of the time, high is 480 volts and low is 208/240 volts. Given that you posted the amperage as "41-38 / 19", I am 99% confident that 41 amps is at 208 volts, 38 amps is at 240 volts and 19 amps is 480 volts. Further below is the way to wire unless the motor manufacturer or name plate indicates differently. You will need to determine the voltage of the appliance this is going to be installed into. You should be able to find this on a name plate of the appliance - but it may provide a dual voltage spec here, too. If this is the case, you will need to *carefully* measure the voltage with a meter, or find out the voltage of the electric panel that feeds the appliance.

Once you have learned the incoming voltage, you will connect the motor as such when L1, L2 and L3 are the line voltage supply wires and wires 1 thru 9 match the numbers on the nine wires from the motor.

208/240 or "Low" volts:
Motor leads 4, 5 & 6 connected together and wirenut.
Motor leads 1 & 7 to L1 and wirenut.;
Motor leads 2 & 8 to L2 and and wirenut and lastly,
Motor leads 3 & 9 to L3 and wirenut.

480 or "High" volts:
Motor lead 1 to L1 and wirenut,
Motor lead 2 to L2 and wirenut,
Motor lead 3 to L3 and wirenut,
Motor leads 4 to 7 and wirenut,
Motor leads 5 to 8 and wirenut and lastly,
Motor leads 6 to 9 and wirenut.

The motor should be operated briefly or "jogged" to determine the direction the motor turns. If the motor rotation needs to be changed, simply swap any two "L" wires (swap L1 and L2, or L1 and L3, or L2 and L3). Test once more to verify rotation and when correct close the wiring compartment and complete the installation. Swapping the L wires will likely be much quicker and easier to do at the magnetic contactor instead of the the motor's wiring compartment. Either location is acceptable.

You should try to obtain the name plate data for this motor - if at all possible to to make sure of the voltage and wiring method. I hope this helps & good luck!

Trying to rewire my ingersoll rand air compressor motor, psi switch motor starter, need some kind of diagram, it has a 5hp single phase 220


Please check out the Web Site Below. It is a Quick Start manual for IR Compressors.

It should have everything you need. It DOES NOT Show you any wiring connections AT the motor.

Hope this helps....Jim

I NEED TO REWIRE A DOERR LR22132 ELECTRIC


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.

The wiring diagram to change the voltage is on the name plate on the motor. The motor leads are numbered. Go by the diagram and reconnect the numbered leads the way it says for 'low voltage'

Rewiring mootor from 230v down to 115v


Diagram for aosmith motor b381 is here: http://www.electricmotorwarehouse.com/IMAGES/B381_connection.htm

However, I believe that this motor will be more efficient at 230v depending on load conditions. At 115v this motor will draw more amps and tend to run hot, but situation rules. Enjoy
