Small motors may be found in electric watches. General- purpose motors with highly standardized dimensions and characteristics provide convenient mechanical power for industrial use. The largest of electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching . An easy-to-understand explanation of how motors use electricity and magnetism to drive machines, with clear illustrations and photos.
The axle holds the armature and the commutator.
Coils of wire are wrapped around the armature, forming one or .
The development of these devices revolutionized society and helped pulled the world into the modern technological era.
Electric motors come in all sizes and configurations, but they all function on the same principle with the same fundamental parts. An electric motor is an electrical machine that converts electrical energy into mechanical energy. The reverse of this is the conversion of mechanical energy into electrical energy and is done by an electric generator, which has much in common wit.
How they work, types of motors and electric motor history. Uses: a clock uses synchronous motors to provide an accurate rotation speed for the hands. You might be surprised to find out just how much work is done by electric motors.
Find out how electric motors get stuff moving.
A secondary school revision resource for Edexcel GCSE Science about electricity in the real world and the cost of electricity. Rabindranath Sahoomonths ago. Is electric motor and generator same ? In this lesson, you will learn what an electric motor is, how it works, and examine some examples of how electric motors are used in everyday life.
The basic function of all and any electrical machine is to make use of the magnetic field produced in the air-gap between stator and rotor for the transfer of and conversion of electrical to mechanical energy commonly know as electro- mechanical en.
They come in many different sizes and configurations. Some electric motors are powerful enough to drive entire vehicles and others are so tiny that they can fit in the . Consider the image on the previous page. The armature takes the place of the nail in an electric motor.
In the diagram to the right, you can see three . In motors , there are two bar magnets across from each other, one south and one north. The field magnets are permanent . With the remaining rotor arms, a motor can produce sufficient torque to begin spinning .
