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

What is Power Factor? Causes, Effects, and Methods of Improvement

-
  Introduction Welcome, future engineers! If you have ever looked at an electricity bill from an industrial unit or read the nameplate of a large motor, you have probably come across the term "Power Factor." It’s a crucial concept in electrical engineering that bridges your theory exams and real-world industrial practice. Understanding it not only helps you score marks but also saves lakhs of rupees in electricity costs. Let’s demystify this important topic together. What is Power Factor? Definition In the simplest terms,  Power Factor (PF)  is a measure of how effectively electrical power is being used. Think of it like this: When you buy a glass of cold drink, you pay for the full glass (what you get). But what if it’s half-filled with foam? You paid for the full volume, but you only get half the actual drink. Similarly, in an AC circuit, not all the power supplied by the electricity board (called Apparent Power) is converted into useful work (called Real Power)...

Interview Q&A/ Technical Round: Short Q&A Section: Q1. What is Electrical Resistance? Resistance is the property of a material that opposes the flow of electric current. It depends on the material, length, cross-sectional area, and temperature of the conductor. Its unit is ohm (Ω). Q2. State Ohm’s Law. Ohm’s Law states that the current flowing through a conductor is directly proportional to the applied voltage, provided temperature remains constant. Mathematically, V = IR. Q3. What is Electric Current? Electric current is the rate of flow of electric charge in a conductor. It is measured in amperes (A) and is denoted by I. Q4. Define Electrical Power. Electrical power is the rate at which electrical energy is consumed or converted into another form. It is measured in watts (W) and given by P = VI. Q5. What is Electrical Energy? Electrical energy is the total work done by an electrical source over time. It is measured in  watt-hour (Wh) or kilowatt-hour (kWh). Q6. What ...
