MOTOR TROUBLESHOOTING
Figure 8.2 illustrates a troubleshooting flowchart which provides logical, step-by-step methods for identifying and correcting motor problems.
Warning: The internal parts of a motor could be at line potential even when it is not rotating. Disconnect all power to the motor before performing any maintenance which could require contacting internal parts.
This is the key for Fig. 8.2 on troubleshooting ac motors.
A. Motor would not start or accelerates too slowly.
B. Motor runs noisy.
C. Motor overheats.
D. Motor bearings run hot or noisy.
