Four motors

Our motor kits were widely used for educational purposes in more than 120 schools, colleges, universities, and other organizations in the United States and other countries. Recently we redesigned and expanded our range of brushless motor kits and experimentation supplies to make them helpful at almost all levels of education.

For advanced physics activities we recommend following the same 3 simple steps as outlined in Basic School Science: select motor kits, choose experimentation supplies, and add spare parts if necessary.

Here are some additional motor selection recommendations for High School / University level.

  • Reed switch motors are the most popular kits. They have all the parts for easy assembly and do not require any special tools. We recommend kit #4 or #13/14.
  • Kit #6 is based on the Hall Effect IC which is common in most industrial brushless motors. However our design is so simple that it was used in Electrical Engineering: Concepts and Applications textbook. It is the most reliable motor.

  • Kit #8 is another popular item – it combines four different motors in one kit. Students may build one motor at a time and learn how different sensors work and how they affect motor performance.

  • New kit #9 extends kit #8 allowing to switch between different motor configurations with a simple turn of a knob.

For most of motor calculations students need to measure rotational speed of their motors. We highly recommend adding an RPM measurement kit (or an attachment). Only one speed measurement tool is really needed for the whole class.

We do not provide here exact plans for your lessons – you, as an educator, can plan them according to your curriculum. This site has plenty of educational materials for all levels.

Calculations page provides useful motor formulas.

Principles of motor operations are explained in How It Works section.
