What is Stator?

A stator is the stationary part of an electric motor or generator, consisting of coils or windings mounted on an iron core, designed to create a magnetic field when electric current flows through it. Simply you can say the house of the motor which inside contains Winding slots, bearing, rotor and fan.

Stator Core: In the past, the stator core has changed from solid iron cores to electrical steel laminated sheets, which greatly minimizes energy losses from eddy currents. Carefully packed together, these laminations provide a core that supports the windings and improves the magnetic flux efficiency. Modern stator cores are now more dependable and efficient because to the use of cutting-edge materials and production processes. High-performance electric cars, for instance, depend on these upgraded cores to optimize power production, output, and efficiency.

Windings: The windings, typically made from insulated copper wires or aluminum wires, are crucial for generating the magnetic field. There are two main types of windings used: distributed and concentrated windings. Distributed windings are spread evenly across the stator slots, producing a more uniform magnetic field, which is ideal for applications requiring smooth operation, like industrial machinery. Concentrated windings, grouped in specific slots, offer higher torque, making them suitable for applications like electric motors in electric vehicles. The choice of winding type directly impacts the machine's performance, efficiency, and application suitability. 

A rotor is a rotating part of a machine that transmits mechanical power or interacts with a magnetic field to produce motion or electrical power.
