How To Find the Right Electric Motor

There are two ways to determine a suitable motor replacement:

CROSS-REFERENCING the Motor Manufacturer’s part number

The most accurate method to find a replacement motor is to cross-reference the manufacturer’s part number or model number from the motor itself. This number is usually found on the nameplate (label) of the motor along with the other nameplate data, such as horsepower, volts, etc.

Note: A motor nameplate sometimes has several identifying numbers, which can be confusing. Keep in mind that some motors are made for other companies who then put their part number on the motor. The key is to locate the motor manufacturer’s part number.

Matching the Motor Specifications

If cross-referencing doesn’t work, another option is trying to match the electrical specifications and physical dimensions of the defective motor itself. It’s important to provide as much information as possible since the slightest difference in shaft size, mounting, or electrical specs can mean the difference between success and failure in a motor replacement.

Electrical Specs: (these can usually be found on the nameplate)

Volts

Amps

RPMs

Service Factor/SF (if applicable)

Number of Speeds

Rotation (CW, CCW, or Reversible)

Phase (1 or 3), in the case of appliance or industrial applications

Physical Dimensions:

Frame Size (if provided) -or-

Length and Diameter of Motor, and

Length and Diameter of Shaft
