FREQUENTLY ASKED QUESTIONS
An induction motor operates on the principle of electromagnetic induction. When alternating current (AC) flows through the stator windings, it creates a rotating magnetic field, which induces current in the rotor, producing torque without direct electrical connection.
Single-phase induction motors: Used for smaller applications (e.g., household appliances).
Three-phase induction motors: More efficient, used in industrial machinery, pumps, and compressors.
Common causes include:
Overloading beyond rated capacity.
Poor ventilation or blocked cooling fins.
Voltage fluctuations (under/over-voltage).
Bearing wear or misalignment.
Use energy-efficient (IE3/IE4) motors.
Ensure proper load matching (avoid underloading).
Regular maintenance (lubrication, cleaning, alignment).
Regularly: Check bearings, lubrication, and cooling systems.
Annually: Inspect windings for insulation damage.
As needed: Clean dust/debris from motor surfaces.
