Testing individually will allow you to find the cable causing the problem. To determine if a cable is bad, you should test each cable individually and ensure none of the leads are touching. Alternatively, if you get a reading of 0, you might have a cable issue. Then inspect each wire and look for infinite readings. To test your motor for short to ground, you’ll need to set the multimeter to ohms and disconnect the motor from its power source. You should test the windings for a “short to ground” in the circuit and open or shorts in the windings. To begin, set the multimeter to read ohms and then test the motor’s wires and terminal. First and foremost, you’re going to need a multimeter to test the windings. You should regularly inspect the windings for wear and tear, but more importantly, you need to analyze their resistance. Unsurprisingly, the windings of an electric motor are vital to its mechanics. Inspect the Motor Windings With a Multimeter If the friction is minor, the bearings might merely require lubrication. That said, if you hear any scraping or feel any friction, you might need to replace the bearings. The bearings should rotate smoothly and the shaft should be able to move smoothly as well. Another way to inspect the bearings is by pushing and pulling the shaft that the bearings attach to. All you’ll need to do is rotate the bearings to ensure they turn smoothly and freely. You must check the bearings regularly because if you continue using a motor with worn-out bearings, it can damage the mechanism and reduce the motor’s efficiency.īearings are easy to inspect. The bearings endure regular wear and tear, so you need to replace them over time. If you’d like to learn more, you can read our comprehensive guide below.Ī motor’s bearings are one of the most common components to go bad. If you know how and what to look for in a motor, you can take action early and prevent your motor from going down and potentially getting damaged.

In order to prevent future downtime and inefficiencies, you must know how to check if an electric motor is going bad. While motors have certainly made significant improvements to the operations of businesses, companies also must maintain their motors to avoid downtime. Today, countless companies rely on electric motors to make their operations more efficient. Our ancestors worked diligently to find solutions to the sluggish processes they experienced, which ultimately led us to the development of motors and automation.
