Look for signs of physical damage, such as cracked brackets, oil leaks from the seals, or excessive dust buildup which can impede cooling. Testing Under Load and Voltage Balance Once the motor passes the offline resistance checks, it is time to verify its operation under actual conditions.
Checking 3 Phase Motor With Multimeter Only: A Step-by-Step Guide
You must lock out and tag out the electrical supply at the main disconnect before touching any terminals or wiring. If they are open, the motor will not run, and replacing the protector is necessary to restore functionality.
While checking the motor windings, you must also inspect the start capacitor for bulging, leaking, or cracks. Once the power is confirmed off, a visual inspection can reveal a lot about the motor's condition.
How to Check 3 Phase Motor With a Multimeter Only
Before beginning any diagnostic procedure, it is critical to verify that the power supply is isolated and locked out to eliminate the risk of electrical shock. The goal here is to verify that the windings are intact and balanced.
