Location Plan
Core Component
Stator: The fixed part, consisting of coil windings and the iron core, generates a magnetic field when energized.
Rotor: The rotating part, consisting of a core and windings, rotates under the influence of the magnetic field.
Primary and secondary windings: The primary winding is directly connected to the power supply to generate a magnetic field, while the secondary winding controls the speed through capacitor phase shifting.
Bearings: Support the rotation of the rotor and reduce friction.
Working Principle
The fan motor is a single-phase capacitor motor. When current flows through the stator windings, a rotating magnetic field is generated. Due to the fact that the starting winding is connected in series with a capacitor, the current in the starting winding leads the current in the running winding by 90 degrees. This creates a rotating magnetic field in both time and space. The rotor generates an induced current in the rotating magnetic field, and the interaction between the current and the magnetic field produces an electromagnetic torque, which drives the rotor to rotate continuously.
Main Types of Faults
1. The motor does not rotate: It could be a fault in the power line, a damaged capacitor, or a broken motor winding.
2. Slow speed: Insufficient lubrication of the bearings, reduced capacitor capacity, or overheating of the motor.
3. Abnormal noise: Bearing wear, loose fan blades, or rotor jamming.
4. Abnormal heat: Poor heat dissipation, excessive load, or short circuit in the winding.
