I just had my electric motor rewound. At first I had 3 wires coming out of it now I have 9 that are number coded. I need to know which wires I need to hook up. The man at the motor shop said don't use


Apparently you have a three phase dual voltage motor. The wiring should be on the nameplate or in the junction box. You will need to know what voltage you have. There are standard wiring diagrams for three phase motors. If he rewound the motor he should have given you a diagram or there should already be one there. If he doesn't help ask for your money back.

How do I reverse a three phase electric motor?


Reversing rotation of 3 phase motors:
CAUTION: Before attempting any repair of electrical equipment verify the power is disconnected to the device.
CAUTION: Three phase motors could potentially be controlled by frequency control systems. It is recommended a trained electrician perform repairs to any electrical system. In particular, consult a trained electrician if the system includes a frequency control system.

Most 3 phase motors can reverse rotation simply by swapping any 2 of the 3 phase wires. A typical 3 phase wiring circuit will include a safety ground wire (usually green) and 3 phase wires, often designated A/B/C, or 1/2/3, or color coded to distinguish each. By swapping the terminal connection of any 2 of the three phase wires, for example, 1 & 2 or 2 & 3 or 1 & 3, but leaving the third phase wire unchanged will reverse the rotation of most motors.

Electric Phases for Hobart Oven


you must understand this : your electric oven must be indicate if it is a single phase( use 3 wires for 230 2 hot wires + 1 Neutral see the diagram like dryer? you must sure about this. Normally any appliance for home are single phase NOT 3 phase.

2) If you electric oven, say 3 PHASES( use 4 WIRES, 3 hot wires+1 Neutral wires) this for industrial application +comercial 270266c5-a0ad-44dc-9f40-e963255d47f5.jpgNOT for home

However if you system is 3 phase you must need to install 3phase transformer.ba1c9d4d-85e3-4744-8ce5-2f25c6e34ad3.jpg

Powermatic 66 wiring problem


Simple solution: switch two of the wires. Doing so will reverse the direction of the motor. You can switch it at the motor or on the electrical plug end.

I need a three phase wiring diagram for 8145-20 model timer.


8145-20 240Volt Paragon timer is not 3-phase.
Clock motor is 240V.
You need a transformer to convert 3-phase to single phase 240V to operate timer.
Then timer outputs can control 3-phase power using 3-phase contactors
Contactor below is 3 phase with 240V coil

I need a wire diagram for a high voltage Baldor motor CAT # 054180 79151 connect to 440VAC it's a 40HP, RPM 3525 , 3PH and it's SPEC# 40F97Z22 please help


Normal wiring for this type of 9 lead motor to 440VAC is
Connect #4 to #7 Connect #5 to #8 Connect #6 to #9
Connect supply phase A to #1 Connect supply phase B to #2 Connect supply phase C to #3
Can you confirm the CAT and SPEC numbers? They do not show up on the Baldor site. If they are correct as listed, you need to call the Baldor help line and find out if this is a special motor.

How do I wire a three phase electric motor to 110 plug


You can't run a 3-phase motor on 110V unless you use a 3-phase inverter. Depending on the size of your motor, these will probably run you around $150 for the least expensive type. Take a look at--- http://americanrotary.com/static-phase-converters.html
