A Good Way to Wire an Electric Motor
s are the tools that use the alternating current (AC) power and transform it to mechanical energy to drive compressors, tools, washing machines and anything else that requires mechanical motion to operate.
Larger motors are generally wired as 3 phase AC motor
s, using all 3 phases of incoming power and not connecting to the electrical neutral line. In addition, direct current (DC) motors can be used in battery power
applications which do not have AC. All of the motors must be wired appropriately to perform the desired motion. Here is a good way to wire an electric motor.
1. Confirm that the motor is a 3 phase AC motor.
Usually this information will be on the motor faceplate. It also can be noted that the motor has 3 connecting wires rather than 2. Confirm the operating voltage that the motor will require from the power distribution system.
2. Figure out the direction that the motor will turn.
The motor nameplate and motor manufacturer's information can explain the needed wiring to make the motor turn in a particular direction.
3. Attach the motor power leads.
Wire the 3 motor leads to the 3 phases of input power. Do not use the neutral line. If the motor does not turn in the desired direction, you can swap any 2 of the 3 motor wires to reverse the direction of rotation of the motor.
