Linear micromotors play a key role in microrobotic systems. They can greatly simplify the drive mechanisms, which is crucial for microsystems. By using permanent magnets, much higher force-to-volume ratio can be obtained than using electromagnets and better drive performance can be achieved. This paper describes the development of a tubular permanent magnet linear motor for the actuation of microrobots. Important design criteria are established by both analytical and numerical methods. The field distribution, the electro-magnetic force, and the stator phase winding inductances are analyzed and predicted by the finite-element analysis taking into account the nonlinear properties and saturation effects of the material. © 2005 IEEE.
