Motors Experiments with motors Motors Electric motors are used to efficiently convert electrical energy into mechanical energy. Magnetism is the basis of their principles of operation. They use permanent magnets, electromagnets, and exploit the magnetic properties of materials in order to create these amazing machines. There are several types of electric motors available today. The following outline gives an overview of several popular ones.
Universal motors can work on either type of power.
Not only is the construction of the motors different, but the means used to control the speed and torque created by each of these motors also varies, although the principles of power conversion are common to both. Motors are used just about everywhere. I once counted over 137 electric motors in my house. In industry, motors are used to move, lift, rotate, accelerate, brake, lower and spin material in order to coat, paint, punch, plate, make or form steel, film, paper, tissue, aluminum, plastic and other raw materials. The rotate as slowly as 0.001 rpm to over 100,000 rpm.
