Abstract :
A novel disk-crawling motor (DCM) utilizing the forces of magnetic attraction, magnetic adhesion, and material resiliency is proposed. The motor is characterized by high-torque low-speed stepped rotational motion. Microprocessor control of the motor allows it to be used as an accurate positioning actuator. The principle of operation, a description of a prototype, and experimental results are presented
