FAQ – Maintenance Tips for Premium Efficiency Motors (YE5 Series)

What are the maintenance requirements for a Premium Efficiency Motor?

To maintain the performance and extend the life of a laeg Premium Efficiency Motor, especially in low-voltage, three-phase asynchronous configurations, follow these key practices:

1. Regular Inspection

Visual Checks: Look for signs of wear, overheating, oil leaks, or loose components. Examine the motor housing and cable connections carefully.

Vibration Monitoring: Track vibration levels to detect potential bearing failure, misalignment, or rotor imbalance early.

2. Bearing Lubrication

Greasing Bearings: Use only manufacturer-approved grease types and amounts. Over- or under-lubrication can cause serious damage.

Scheduled Maintenance: Set up a routine lubrication plan tailored to your operating environment and motor usage intensity.

3. Electrical System Checks

Insulation Resistance: Use a megohmmeter to test winding insulation. Low resistance may indicate moisture or aging insulation.
Terminal Tightness: Ensure all electrical terminals and connections are secure to avoid overheating and current leakage.
