Types Of AC Motors And Its Practical Application In Real Life - Byju's

AC Motors classification based on Structural Features:

• Open
• Closed
• Semi-enclosed
• Ventilated
• Pipe-ventilated
• Riveted Frame-eye

But, AC Motors are classified into two types:

• Synchronous Motor
• Induction Motors

A flowchart for the classification of AC motor is given below:

A description of each type of AC motor is given below:

Synchronous Motors

The rotational speed of the stator current is equal to the rotational speed of the rotor. They don’t have a slip with respect to stator current.

Asynchronous Motors

These motors slip with respect to the stator current field. They are used in different varieties of pumps etc.

Single Phase and Three Phase Motors

Single-phase motors are used in domestic appliances. Three-phase motors are used in high-power appliances.

Constant,Variable & Adjustable Speed Motors

• Flexible for controlling speed.
• Constant speed is performed in air compressors.
• Cooling pumps can function at variable speeds by making a switch in the number of poles used. Changing the number of poles results in speed change.
• Motor’s speed can also be changed accordingly with some electronic arrangements, which are ideal for the ship’s cargo pump where the discharge rate needs to be lowered as per the requirement of the tunnels.

Varied Structure Motors

Depending upon the industrial requirements, motors have a variety of outer cage arrangements. For example, motors that are used in oil and gas terminals should have safely enclosed casing to prevent sparks produced in the motor from causing fire outside of it.

Frequently Asked Questions – FAQs

Q1

How does current electricity work?

The steady flow of electrons is termed as current electricity. When electrons move from one point to another in a circuit, they carry electrical energy from place to place.Q2

What are the main elements or components of an AC circuit?

The main components of AC circuits are resistors, capacitors, and inductors. Q3

What is a capacitor?

A capacitor is an electrical component that stores electric energy in an electrical field.It is a passive electrical device with two terminals.Q4

What are the main types of AC circuits?

AC circuits can be divided into three categories: Resistive (R), RC, RL, and RLC circuits.Q5

Define AC current.

The current electricity that is bidirectional and keeps changing the direction of the charge flow is known as alternating current. Test your Knowledge on Types Of AC Motors Q5
