Abstract

Various aspects of micromotors and electric drives were discussed. The fundamental constraints on the performance of micromotor technology were studied. The aspects of performance included energy density, force density, size, constraints on motor-drive circuitry, motor topologies and friction. Analysis showed that electrostatic machines were advantageous, as microfabrication processes achieve finer resolution and could exceed the energy and force density capabilities of conventional magnetic machines.
