Precision positioning stages based on the principle of magnetic levitation find widespread use because of their large motion range and high positioning resolution.However, most of these stages are levitated by employing feedback control.Here, we propose a diamagnetically levitated actuator wherein the actuated magnetic platform is sandwiched between two identical printed circuit boards (PCBs).This configuration enables independently controlling the 3D electromagnetic forces acting on the platform and also increases the payload-carrying capacity of the platform.A mathematical model of the system is developed and is used to analyze the dependence of forces on the actuation currents flowing through the PCBs.Finally, the development of the actuator is discussed along with experiments demonstrating independent control of motion along X- and Z-axes.
