Why Starting Torque of Squirrel Cage Induction Motor is Low?
The starting torque of an induction motor is very low compared to its rated torque. The torque of an induction motor depends on the rotor
Why Power in Pure Inductive and Pure Capacitive Circuit is Zero?
This article describes why the power in pure inductive and capacitive circuits is zero. The inductors and capacitors are the basic building blocks of an
What is the importance of slip in an induction motor?
The induction motor can’t run if there is no slip. What is a slip of an induction motor? Let us first understand the slip of
Transformer Oil: Testing, Types & Properties
💡 Key learnings: Transformer Oil Defined: Transformer oil (insulating oil) is essential for cooling, insulation, and protecting transformers from oxidation. Types of Transformer Oil: Two
Why Induction Motor Has Poor Power Factor at No Load
Induction motors have a low power factor at no load because they draw a large magnetizing current to create the magnetic field, while the actual
Deep Bar Double Cage Induction Motor: Construction, Working & Speed-Torque Analysis
💡 Key learnings: Deep Bar Double Cage Induction Motor Definition: A motor with a double-layered rotor designed to enhance starting torque and efficiency. Starting Torque
Difference Between Ohmic and Non-Ohmic Conductors
💡 Key learnings: Ohmic Conductors: Obey Ohm’s Law; current is directly proportional to voltage. Resistance remains nearly constant under normal conditions. Non-Ohmic Conductors: Do not
Why Transformers Are Rated in kVA, Not in kW
Transformers are always rated in kVA (kilovolt-amperes) rather than kW (kilowatts) because their design is based on voltage and current capacity, not the power factor
Why Motor Rated in KW instead of KVA?
A motor is rated in kilowatts (kW) because its primary purpose is to produce useful mechanical output power to drive a load. Kilowatts represent the
Difference Between kVA and kW – Explained With Formulas & Examples
💡 Key Learnings: kW (Active Power): kW measures the real power consumed by electrical equipment to perform actual work. kVA (Apparent Power): kVA represents the
