Electric Motor Overloading Causes and Protection!
Electric Motor Overloading Causes and Protection!
Causes of Overloading:
1. Excessive Load – Motor operates beyond its rated capacity.
2. Low Voltage – Causes higher current draw, leading to overheating.
3. Frequent Starts & Stops – Increases stress and heat buildup.
4. Blocked Ventilation – Poor cooling leads to overheating.
5. Bearing or Mechanical Issues – Increased friction raises motor load.
Protection Methods:
✔ Overload Relays – Automatically disconnects power when overload occurs.
✔ Proper Sizing – Use a motor suited for the load.
✔ Adequate Cooling – Ensure vents are clear and the motor is well-ventilated.
✔ Voltage Monitoring – Maintain proper voltage levels.
✔ Regular Maintenance – Inspect bearings, connections, and load conditions.
Ignoring overload issues shortens motor life and increases fire risks! Always monitor and protect your motors.
