Electric Motors
principles and factors affecting their efficiency

 This project consists of two main parts. In the first part you study electric motor principles and how they work. In this part we may also build a working model of an electric motor. 

 In the second part you learn about efficiency of electric motors and how it is defined and calculated. You then study the factors that may affect the efficiency of electric motors.

 Project description
Building a working electric motor is a fun and memorable experience. During this project you will discover possible designs of electric motors and build your own electric motor. You will also design an experiment to measure the efficiency of an electric motor. Finally you will test to see what factors may affect the efficiency of an electric motor.
