Technical Examples

A kind of 2-D variable reluctance planar motor comprises: a stator base combined by a plurality of laminated steel bricks; a moving platform consisting of two rows of spaced coil-shoes; traditional sliding supports to hold said platform above said stator base; two electronic rulers for scaling the real position of the platform; traditional supporting means for holding the platform at a distance above the stator base; computer and software for generating motion command signal to PWM generator; PWM current generator for energizing the coils of the moving platform; when a reference data (the final position of the platform) is input into the computer, the computer will give command to the platform and make it moving; once the moving platform is set in motion, the electronic rules continuously detect and transfer the location data of said platform to the computer; the computer continuously compares the data sent by said rules with reference data and gives command to the platform until said two kinds of data are equal. The planar motor of this invention uses no magnets, no constant air-gap and no accurately manufactured component. The working accuracy can easily reach 0.001 mm and the cost is very low.
