Abstract:
1. A two-dimensional variable reluctance planar motor, comprising: a stator base including a plurality of laminated steel bricks; a moving platform including two rows of spaced coil-shoes and coils; sliding supports for holding the platform above the stator base; two electronic rulers for scaling the real position of the platform; supporting means for holding the platform at a distance above the stator base; a PWM current generator for energizing the coils of the moving platform; and a computer having software for generating motion command signals to the PWM generator; wherein, when a reference data is input into the computer, the computer transmits a command to the PWM generator to move the platform, as the platform moves, the electronic rules continuously detect and transfer location data of the platform to the computer, the computer continuously compares the data sent by the rules with the reference data and continues to transmit commands for moving the platform until the location data is equal to the reference data.
