# Question: What is a simple electric motor?

Contents

The basic idea of an electric motor is really simple: you put electricity into it at one end and an axle (metal rod) rotates at the other end giving you the power to drive a machine of some kind. … When an electric current starts to creep along a wire, it creates a magnetic field all around it.

## How does a simple electric motor work?

This simple electric motor works by the magnetic force F = IL x B. … The magnetic field at both of these spots points in the same direction. Thus, the magnetic force on the wire at opposite ends of the loop points in opposite directions, causing it to spin.

## How do you make a simple electric motor?

Materials

1. D battery.
2. Insulated 22G wire.
3. 2 large-eyed, long, metal sewing needles (the eyes must be large enough to fit the wire through)
4. Modeling clay.
5. Electrical tape.
6. Hobby knife.
7. Small circular magnet.
8. Thin marker.

## What is electric motor with diagram?

An electric motor is a device that converts electrical energy into mechanical energy. Diagram: Electric motor. Working of an electric motor: An electric motor works on the principle of magnetic effect of electric current. In an electric motor, a rectangular coil ABCD in placed between two magnets in poles N and S.

## What are the 6 parts of an electric motor?

These six components include:

• 1) The Rotor. The rotor is the moving part of your electric motor. …
• 3) The Bearings. The rotor in your electric motor is supported by bearings, which allow it to turn on its axis. …
• 4) The Windings. …
• 5) The Air Gap. …
• 6) The Commutator. …
• What Do All of These Components Have in Common?

## What are the parts of a simple electric motor?

The components of an electric motor may include a rotor, thin sheets of stacked metal called laminations, a stator, wire windings, magnets, a commutator, brushes, poles, electrical interconnects and a housing.

## Where do we use electric motors?

The largest electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts. Electric motors are found in industrial fans, blowers and pumps, machine tools, household appliances, power tools and disk drives.

## How do you make an electric motor more powerful?

We can increase the turning force (or torque) that the motor can create in three ways: either we can have a more powerful permanent magnet, or we can increase the electric current flowing through the wire, or we can make the coil so it has many “turns” (loops) of very thin wire instead of one “turn” of thick wire.

## Can I use an alternator as a motor?

We’ve found that an alternator drives well as a motor from a 36V or a 48V supply, and as long as a controller with enough power is used then they do so reliably. … Having to use that power makes the motor a bit less efficient than a permanent magnet one, but the cost of a scrap alternator is hard to beat.

## Why are electric motors important?

More than 40% of generated electricity is consumed by industry, and two-thirds of that energy is used by electric motors. By using more efficient motors it would be possible to achieve huge savings in both energy and carbon dioxide emissions.

## What is motor principle?

12.2 Introduction and definition of the motor principle

The principle of the electric motor is that it converts electrical energy into kinetic energy (mechanical energy) through the interaction of the two magnetic fields.

## Why commutator is used in electric motor?

On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils.
