How to Check an Electric Motor

Wednesday - 29/04/2020 13:29
When a motor fails, it is often difficult to see why it failed just by looking at it. A motor placed in storage may or may not work, regardless of its physical appearance.
How to Check an Electric Motor
A quick check-out can be done with a simple ohm meter, but there's a lot more information to collect and weigh before actually putting it to use. At no time during the motor check out is power required. If it is connected - disconnect it before attempting the steps below.
 
Checking the Outside of the Motor
 
1 Check the outside of the motor.
 
If the motor has any of the following issues on the outside, they may be problems that can shorten the life of the motor because of previous overloading, wrong application, or both. Look for:
 
Broken mounting holes or feet
 
Darkened paint in the middle of the motor (indicating excessive heat)
 
Evidence of dirt and other foreign matter having been pulled into the motor windings through openings in the housing
 
2 Check the nameplate on the motor.
 
The nameplate is a metal or other durable tag or label that is riveted or otherwise affixed to the outside of motor housing called the '"stator" or "frame". Important information about the motor is on the label; without it, it will be difficult to determine its suitability to a task. Typical information found on most motors include (but not limited to):
 
Manufacturer's Name — the name of the company the made the motor
 
Model and Serial Number — information that identifies your particular motor
 
RPM — the number of revolutions the rotor makes in one minute
 
Horsepower — how much work it can perform
 
Wiring diagram — how to connect for different voltages
