5 Tests for Troubleshooting an Electric Motor

Keeping up with motor health can result in a longer lifespan and fewer repair costs. Regular monitoring and testing can help you to keep track of variables that may affect motor operation. Tests can reveal a lot about the condition of a motor.

1. The Hipot Test

Cables and wiring can fail with age, so determining their status is important. The hipot test checks for weaknesses and failure potential in a motor's wiring. Run 'Em Again Motors in Glendale has certified technicians who can run all kinds of motor tests for you.

2. The Voltage Drop Test

The voltage drop test is the fastest, easiest test to run on a motor. It can quickly inform you of the efficiency and quality of the motor's electrical circuit. The test measures the connection for a drop in voltage under load. If a voltage drop occurs, cleaning or a simple repair may be all that's required to improve performance.

3. The Megger Test

The Megger test uses a megohmmeter insulation resistance tester to determine insulation performance. A high voltage is applied to the system to see where insulation leaks may be happening. When tested regularly, the results can map wear over time. With this information, the operator of the tool or appliance can determine when it's time to maintain the equipment.

4. The Surge Test

Surge testing can find evidence of electrical failure or motor burnout. This test is run by applying a surge or voltage pulse to the motor's windings. The test data can identify each winding's performance individually and then in comparison to each other. IEEE 522 defines surge testing standards for a broad range of winding conditions and types.

5. The Core Loss Test

To guarantee reliability and quality, the core loss test charts the existing input and output power levels of the motor. Compared against industry standards, necessary repairs and maintenance needs can be determined.
