The induction motor, discovered by Nikola Tesla in the late 1800s, has become an essential element in contemporary electrical engineering, powering a diverse array of industrial and residential applications. Over time, it has embedded into a crucial component driving various devices, from household gadgets to massive industrial machinery.

Basic Operating Principle
Fundamentally, the induction motor functions on the principle of electromagnetic induction, a concept pioneered by Michael Faraday. This principle posits that a changing magnetic field induces an electromotive force (EMF) in a conductor. In the induction motor, the rotor serves as this conductor, and the changing magnetic field results from alternating current (AC) coursing through the stator windings.

1. Stator: Constituting the stationary part of the motor, the stator comprises a laminated iron core with evenly spaced windings. The application of AC voltage to the stator windings generates a rotating magnetic field.
2. Rotor: Constructed mainly from a laminated iron core, the rotor rotates freely within the stator. As the rotating magnetic field induced by the stator generates an EMF in the rotor, it produces current, creating a magnetic field that propels the rotor into motion.
3. Bearings: Bearings play a pivotal role in ensuring smooth rotation of the rotor shaft. Regular lubrication and maintenance are critical for sustaining the motor's efficiency and longevity.

Types of Induction Motors
Electrical outlets in residences are powered by 115 V or 230 V single-phase power. A single-phase motor is one that receives only one voltage waveform. Three-phase, 230 V, 460 V, or 575 V or higher, have three wires that deliver voltage waveforms at various times. Three-phase is more efficient and cost-effective, and it is used in industrial settings for heavy-duty equipment using three-phase motors.
1. Single-Phase Induction Motors: Primarily used in residential settings, these motors are simpler in design and operate on a single-phase AC power supply.
2. Three-Phase Induction Motors: Predominantly employed in industrial contexts due to their efficiency and dependability, these motors necessitate a three-phase AC power supply. They outperform single-phase motors in terms of power and performance.
