How can one assess the health of a motor, and what parameter ranges are typically expected?

Question

Accepted Answer

Assessing motor health involves monitoring parameters like vibration, temperature, and current to ensure optimal performance.

Vibration analysis: Excessive vibration can indicate misalignment or bearing issues. Typical values are below 0.1 in/sec.
Temperature monitoring: Motors should operate below 80°C. Higher temperatures can signal overload or insulation failure.
Current draw: Compare actual current to rated current. A significant increase may indicate mechanical issues or overload.
Insulation resistance: Should be above 1 MΩ. Lower values can indicate insulation breakdown.
Noise levels: Unusual sounds can indicate mechanical problems. Regular checks can help identify issues early.
