Abstract
The paper describes magnetically levitated planar actuator with moving magnets. The translator part is represented by a disc permanent magnet or a uniform shaped object fulfilling specific requirements, so that it can provide sufficient control force against the lateral forces and the gravity force of the carrier. The stator platform is represented by 16 identical coils and a microcontroller board for precise coordination of the translator. The coil currents are controlled by PWM signals, in such a way, so together would form a homogenous magnetic field slightly above the planar surface of the coil array. As only the coils can produce significant force and torque, the current through them is switched during the movements of the translator. The system fulfils all the design requirements and its functionality was verified in the laboratory.
