15 key differences: Single-phase vs Three-phase Induction motor

difference between a single-phase and a three-phase induction motor

An induction motor is the most commonly used AC motor in homes, offices, and industries. The reasons are its low cost, rugged construction, and sufficiently high efficiency. Based on the AC power supply given to the motor, there are two types of Induction motors, viz, Single-phase and a Three-phase Induction motor. In this article, we … Read more

Speed Control of a Synchronous motor: Methods & Applications

Speed control of a Synchronous motor

A Synchronous motor is a type of AC motor that runs at a constant speed. And before discussing the speed control methods of a Synchronous motor, let us see how to find the speed of a synchronous motor. Using this simple formula: , we can calculate the synchronous speed of any synchronous motor.Let’s look at … Read more

Single phase Induction motor: Construction, Working & Starting methods

single phase induction motor

A single-phase induction motor is a type of AC motor which consists of a single-phase winding on the stator and requires a single-phase AC supply to create a working flux for the motor. But have you ever thought, why do we need a single-phase induction motor when we already have a three-phase induction motor?It is … Read more

Synchronous Motor: Working principle, Starting methods & Types

synchronous motor

A Synchronous motor is a type of AC motor which runs at a constant speed, known as synchronous speed. The rotor in a synchronous motor always maintains synchronism with the rotating magnetic field of the stator. Even the load variations do not alter the motor’s synchronism. Hence, synchronous motors are used in constant speed applications. … Read more

Induction Motor: Construction, Working principle & Advantages

induction motor

An Induction motor is the most widely used AC motor in industrial and domestic applications. Now you might think, why is it so? It is because of the low cost, simple and rugged construction of the motor. Moreover, it has good operating characteristics with an efficiency as high as 90%. An induction motor does not … Read more

Types of AC Motors: Wound, Squirrel cage, Reluctance, Hysteresis & more

Types of AC motors

An AC motor requires an AC input to produce a rotating magnetic field. This field interacts with rotor conductors and makes it rotate with the stator field. The two main types of AC motors are Induction motors and Synchronous motors. The figure below shows a detailed explanation of AC motors. **Before starting the types of … Read more
