The Different Types of Electric Motor

The electric motor stands as a cornerstone of modern engineering. It powers everything from household appliances to industrial machinery and now even the personal car. At its core, a standard electric motor comprises several key components working in harmony. A rotor sits within a stator usually surrounded by an enclosure or frame. Differential energisation of electrical coils within the motor facilitate a changing magnetic field which induces the rotor to turn. There is usually some way to mount the motor, as well as a way to wire it to a power source. Together, these elements form the fundamental structure of the electric motor, converting electrical energy into mechanical motion with remarkable efficacy. In this review, we look at some of the different types of electric motor in use today. These different devices are distinguished by their internal workings which usually also determines their suitability for a particular application.
