Overview

The electric machine has been used to generate electric energy since the beginning of electric power. In electric drive, electric machines are used to produce mechanical energy that can be used for electric motor in machines as well electric vehicles like cars and trucks.

They are also finding immense application in the field of electric drives especially motors of any configuration viz dc, ac or dqc motors where they provide high torque at low speed. They also provide high speed at relatively low torque.

As the electric machine is used in electric power generation, electric vehicles and electric motors, they are available in wide range of ratings like AC induction motors , DC shunt motors , Universal electric machines or D type electric motor etc. The electrical machine is a transducer which generates electric energy from mechanical energy and electric motor is a transducer which converts electric energy into mechanical energy.

Thus, electric machines are one of the major inventions in the field of science and technology that has revolutionized the entire modern world we live in today. They are used to offer electric machines assignment help not only to students but also to industries where they are used to electric motors for electric vehicles, electric generators and electric drives of all types.
