1. The Stationary Powerhouse: Stator

• The stator is the stationary outer shell of the motor.
• It contains stator windings—precisely wound coils of wire.
• When alternating current (AC) flows, they create a rotating magnetic field.
• This field gets the motor spinning.
• The stator is mounted inside the motor frame for protection and structure.

2. The Spinning Core: Rotor

• The rotor sits inside the stator and spins.
• Most common: the squirrel cage rotor, made of conductive bars in a laminated core.
• The stator’s field induces current in these bars.
• This interaction makes the rotor turn.
• The conductive bars are also called rotor windings.

3. Connecting the Motion: Shaft

• The shaft extends from the rotor to transfer energy.
• It connects to pumps, fans, or conveyors.
• Essentially, it’s the output of the motor.

4. Smooth Operators: Bearings and End Bells

• Bearings support the shaft, reducing friction.
• End bells enclose and protect bearings, keeping out dust.
• Together, they ensure durability and reliable operation.

5. Keeping it Cool: Cooling Fan and Fan Cover

• Motors generate heat during use.
• A cooling fan on the shaft circulates air to dissipate heat.
• The fan cover protects the fan and directs airflow.

6. The Electrical Gateway: Terminal Box

• The terminal box connects external power cables.
• It links to the stator windings.
• This ensures safe delivery of electricity.

Summary

An induction motor is a marvel of engineering—a precisely coordinated system where each part plays a critical role in converting electrical power into reliable motion, silently powering much of our modern world.
