Electric Motor
 

Electric Motor Overview

Electric motors are everywhere. They vary in physical dimension from the size of a building to the size of a dime. We use electric motors for daily tasks inside our household appliances, phones, air conditioners and toys. We use them everywhere because they are simple and efficient. Electric motors have just two main parts: a rotor that spins around and a stator that remains stationary.

 

Most electric motors are sized to meet their particular application. They are set up to deliver current as necessary for the task. Current amperage is proportional to torque (the more amperage delivered – the more torque produced), and at constant speed, torque is proportional to horsepower (the more torque delivered, the more horsepower produced).
