Toward the design of successful electric micromotors

Various characteristics of electric micromotors are considered as well as the relations between those characteristics, in an attempt to organize the process by which successful micromotors can be designed. Special attention is paid to electromechanical characteristics. The resulting organization illuminates the interdisciplinary nature of the physics behind micromotor analysis and design and suggests specific research problems which should be pursued to support micromotor design, fabrication, and performance. A simple design example which considers the impact of friction torque on the top speed of both variable-capacitance and induction rotary micromotors is provided for illustration.<
