Difference Between Motor and Generator - A Complete Guide

In this article we are going to learn about generator motor, difference between electric motor and electric generator , working principle of motor and generator and many more

What is mean by motor or Electric motor

Electrical energy is converted into mechanical energy using an electric motor.

Let's look at an example:

What is the purpose of the mixer in your home?

Things are mashed and mixed for you by rotating blades.

And what would you say if someone asked you how that works?

You'd probably say it's powered by electricity.

That isn't entirely correct.

Motors are machines that turn electrical energy into mechanical work.

Generators, on the other hand, turn mechanical work into electrical energy.

The following are the components of a basic motor:

For a simple motor, a power supply – mainly DC

A permanent magnet or an electromagnet could be used as a field magnet.

An armature, often known as a rotor

Commutator

Brushes

Axle

Working principle of electric motor

The operation of an electric motor is dependent on the creation of a magnetic field around a current carrying conductor.

Consider the following scenario to gain a better understanding.
Keep the poles of two bar magnets facing each other with a tiny gap between them.

Make a loop using a tiny length of conducting wire now.

Maintain this loop in the middle of the magnets in order to keep it in the magnetic effect in that area.

The final step is connecting the loop's tip to the battery connections.

You'll notice that your loop "moves" after energy passes through your simple circuit.

So, what causes this?

The magnetic field produced by the magnets interferes with the magnetic field produced by the electric current passing through the conductor.

One side of the loop will be attracted to the north pole of the magnet, while the other will be attracted to the south pole.

The loop will continue to rotate as a result of this.

This is the principle of working of electric motor.

Uses of an Electric Motor
Electric motors are utilised for a wide range of purposes.

The following is a list of some of them.

• Drills, water pumps, hard disc drives, washing machines, and other industrial machinery

What is the definition of an electric generator?

Electric generators, usually referred to as dynamos, are machines that transform mechanical energy into electrical energy.

Steam turbines, gas turbines, and wind turbines are the most common sources of mechanical energy for electric generators.

The following are the key components of an electric generator.

• The Frame
• The alternator
• A fuel system
• A Voltage Regulator
• A cooling system
• A Lubrication System
• An exhaust system
• A charger
• The main control panel

Working principle of generator

Generators do not generate electricity; instead, they use mechanical energy to compel electric charges present in the wires of their windings to travel through an external electric circuit.

The generator's output electric current is made up of this flow of electrons.

Michael Faraday established the principle of electromagnetic induction, which is used in modern generators.

He noticed that moving an electrical wire in a magnetic field may produce the above current flow.

This movement creates a voltage differential between the conductor's two ends, causing electric charges to flow and therefore creating current.

Electric Generator Applications

1. They are the source of energy for the majority of power networks in cities.
2. Small generators are an excellent backup for residential or small company power demands.
3. Electric generators are widely used on building sites before the power is installed.
4. Fuel usage is considerably reduced, making it energy-efficient.
5. They are utilised in laboratories because they provide a wide range of voltage output.
6. They're utilised to power electric motors.
7. They are utilised in the transportation industry.

Difference between pump and motor / difference between motor and pump

• An electro-mechanical device that turns electrical energy into mechanical energy is known as a motor.
• Using suction or pressure, a pump raises or moves fluids.
• Prime movers include electrical motors.
• Pump is a hydraulic device that increases fluid pressure.
• Fans, compressors, conveyor systems, robotics, electric vehicles, lifts, lathe machines, vacuum cleaners, grinders, shearing machines, and other motors are all employed in virtually everything.
• Pumps can be found in both commercial and industrial settings.
• Pumps can be found in everything from water treatment plants to paper mills.

Difference between machine and structure

From a subject standpoint, the following distinctions between a machine and a structure are critical.

• The members of a structure do not move relative to one another, whereas the parts of a machine do.
• A machine converts available energy into useful work, whereas no energy is converted into useful work in a structure.
• A machine's link can convey both power and motion, whereas the members of a structure can only transmit forces.
• For example, a machine: a lathe, a prime mover, and a structure: a bridge, a building, and so on.
