General project description
The ball bearing motor is a mystery because to this day as no engineer knows how it works! No one understands the physical principle at all. Your job is to do some experiments to investigate this motor and why it is that it rotates. Understanding the principle is important. It may not be useful for large motors, but it may be interesting for micromotors and micropumps that have numerous applications.
Abstract

Weekly progress and questions
Background
Specific Tasks
- Step 1: Film the construction and operation of the motor.
- Step 2: Use COMSOL to simulate the motor to see if you can investigate what happens in simulation.
- Step 3: Characterize the motor. Using an encoding wheel and a photosensor, plot curves of torque versus angular velocity of the motor.
