# What is the purpose of an electric motor?

Contents

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.

## How does an electric motor work simple?

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 makes an electric motor more powerful?

The strength of the motor (torque) is determined by voltage and the length of the wire in an electromagnet in the stator, the longer the wire (which means more coils in the stator) the stronger the magnetic field. This means more power to turn the rotor.

## What is an electric motor made of?

What’s Inside an Electric Motor? The coil is made of copper wire, because copper is such an excellent conductor. It is wound onto an armature. The coil becomes an electromagnet when a current flows through it.

## What is the function of shaft in electric motor?

The Shaft: This takes the rotational energy from the electric motor’s spinning and provides a means to harness that energy via a mechanical connection: a piece of metal that extends through and outside of the frame. The Stator: This remains stationary, usually constituting the field magnet for the electric motor.

## 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.

## Why do electric motors lose torque at high rpm?

Because doing so would compromise efficiency and drivability. As engine speed increases, so does it’s inefficiency. Higher RPMs cause more wear, and waste more fuel. For that reason, vehicles usually cruise at a engine speed much below the point where they make maximum power.

## What size electric motor do I need?

General rule of thumb: you need at least 2 lbs. of thrust for every 100 lbs. of fully-loaded boat weight (people and gear included).

## Can an electric motor generate electricity?

Converting energy from one form to another is the key to understanding the differences between electric motors and generators. 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 are the two main components of an electric motor?

The two main components of this kind of motor are the stator (stationary element) and the rotor (rotating element).

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

Motor Components

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.

## How does an electric motor start?

It starts with the battery in the car that is connected to the motor. Electrical energy is supplied to the stator via the car’s battery. The coils within the stator (made from the conducting wire) are arranged on opposite sides of the stator core and act as magnets in a way.
