This condition will cause immediate tripping of protection devices and requires winding replacement or motor servicing. Look for signs of physical damage, such as cracked brackets, oil leaks from the seals, or excessive dust buildup which can impede cooling.
Troubleshooting 3 Phase Motor Not Running: Key Checks and Solutions
You will test between each pair of terminals—typically labeled U, V, and W for the phases. Ensuring that the connectors are tight and clean is a simple yet critical part of the checking process that often resolves running issues without further intervention.
The goal here is to verify that the windings are intact and balanced. Turn the multimeter to its resistance or diode test mode, and again measure from each terminal (U, V, W) to the metal frame of the motor.

Move the probes to terminals V and W, and then W and U, completing the triangle test. Use the multimeter to check these devices for continuity; they should conduct electricity when the motor is cold.
