Parts of Three Phase Induction Motor

 

Part	Function	Material Used
Stator	Generates a rotating magnetic field when supplied with 3-phase AC power	Laminated electrical steel sheets, copper or aluminum windings
Rotor	Responds to the magnetic field, generating torque and causing rotation	Aluminum or copper bars and end rings
Bearings	Support the rotor and reduce friction for smooth rotation	Steel, with components like steel balls or rollers
Frame	Provides structural support for the motor and dissipates heat	Cast iron or aluminum
End Covers	Enclose the motor, protecting internal components	Cast iron, aluminum, or plastic
Cooling Fan	Dissipates heat during operation, maintaining a safe temperature	Plastic or metal
Terminal Box	Houses electrical connections for stator windings	Plastic or metal, with insulation
Shaft	Connects the rotor to external equipment, transmitting mechanical power	Steel, stainless steel, or suitable material
Enclosure	Protects internal components from environmental factors	Cast iron, aluminum, plastic, or other materials
Stator Winding	Consists of insulated copper or aluminum wire coils that generate the magnetic field in the stator	Copper or aluminum wire with insulation
Rotor Winding	Made up of insulated copper or aluminum bars and end rings, responding to the magnetic field in the stator	Copper or aluminum bars with insulation
Eye Bolt	Provides a lifting point for handling and installation of the motor	Steel or other suitable materials for strength and durability
Slip Rings	Electrical components used in slip ring rotors to transfer electrical power and control signals to the rotor	Typically made of brass, copper, or other conductive materials
Carbon Brushes	Brushes that maintain contact with the slip rings, allowing for the transfer of electrical current	Made of carbon or other suitable materials with good conductivity
