# What is the role of electric motor and generator in our daily life?

Contents

The purpose of an electric motor is to convert electrical energy into mechanical energy. This mechanical energy can then be used to power everything from heavy, industrial machinery to everyday tools and appliances such as hair dryers.

## How are motors and generators useful in our daily life?

Huge diesel generators are often trailed in to support the machinery, trailers, ventilation, water pumps, security, and more, with portable generators powering table saws, grinders, drills, and other power tools. There’s even a special class of generators for welding that combines a welder with a generator.

## What is the function of electric motor and generator?

An electric motor converts electricity into mechanical energy, providing a power source for machinery. A generator does the opposite of this, converting mechanical energy into electricity.

## What is the role of electric motor?

An electric motor is a device used to convert electricity into mechanical energy—opposite to an electric generator. They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field.

## Why do we need generators in our daily life?

Electric generator, also called dynamo, any machine that converts mechanical energy to electricity for transmission and distribution over power lines to domestic, commercial, and industrial customers. Generators also produce the electrical power required for automobiles, aircraft, ships, and trains.

## What are the similarities and difference between electric motor and generator?

The Difference Between Electric Motor and Electric Generator in Tabular Form

Electric Motor Electric Generator
The shaft of the motor is driven by the magnetic force generated between the armature and the field. In electric generators, the shaft is attached to the rotor and is driven by the mechanical force.

## How does a basic electric motor work?

This simple electric motor works by the magnetic force F = IL x B. The current goes around the coil so that it points one direction in one end of the loop and in the other direction at the other end of the loop. The magnetic field at both of these spots points in the same direction.

## What is the principle of generator?

Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. The conductor coil along with its core is known as an armature.

## Why are electric motors so important?

Electric motors impact almost every aspect of modern living. Refrigerators, vacuum cleaners, air conditioners, fans, computer hard drives, automatic car windows, and multitudes of other appliances and devices all use electric motors to convert electrical energy into useful mechanical energy.
