What are the main components of an induction motor?
2 Answers
An induction motor primarily consists of the following main components:
1. **Stator**: The stationary part of the motor, which includes the outer core and winding. The stator winding is connected to the power supply and generates a rotating magnetic field.
2. **Rotor**: The rotating part of the motor located inside the stator. It is typically made of laminated iron sheets and can be of two types:
- **Squirrel Cage Rotor**: Consists of conductive bars short-circuited at both ends by end rings.
- **Wound Rotor**: Contains windings similar to the stator winding, connected to external resistors or devices for better control.
3. **Air Gap**: The small space between the stator and rotor, where the magnetic field induces currents in the rotor.
4. **Frame**: The outer shell that supports and protects the internal components of the motor.
5. **Bearings**: Support the rotor and allow it to rotate smoothly within the stator.
6. **End Bells (or End Shields)**: Cover the ends of the motor, providing mechanical support and housing the bearings.
7. **Commutator (in some designs)**: Used in certain types of induction motors to switch the direction of current flow in the rotor windings, though it's not common in squirrel cage designs.
These components work together to convert electrical energy into mechanical energy through electromagnetic induction.
