• For dusty or wet environments, choose TEFC or IP55 motors.

4. Initial Testing

• Run the motor without load to check for noise, vibration, or overheating.

• Measure the starting current and running current for consistency.

• Check for smooth torque and rotation direction before connecting to equipment.

Correct installation prevents early failures and ensures the motor operates at peak efficiency.

Maintenance Tips for Longer Life

The 0.34 HP / 0.25 KW 3-phase motor requires minimal maintenance, but following a regular schedule extends its lifespan significantly.

1. Lubrication

• Many small motors come with sealed bearings, requiring no lubrication.

• If not sealed, lubricate lightly based on the manufacturer’s guidelines.

2. Electrical System Checks

• Inspect the wiring and connections periodically.

• Perform insulation resistance testing to ensure safety.

3. Cleaning & Cooling

• Dust buildup can restrict airflow, leading to overheating.

• Clean the motor housing and cooling fins regularly.

4. Vibration Monitoring

• Excessive vibration signals misalignment or bearing damage.

• Early detection prevents costly repairs.

5. Load Monitoring

• Avoid running beyond rated capacity for long durations.

• Install overload relays for protection against power surges.

When maintained properly, this motor can last 8–12 years even under continuous operation.
