Abstract:
The feasibility of magnetic levitation applications has been successfully shown for additive manufacturing operations. Through optimization, an ideal levitator setup has been designed. The system, however, is still susceptible to impedance issues. Impedance is defined as the opposition to the current flow offered by a circuit. The primary difference between impedance and resistance is that the impedance also accounts for the effect of the capacitance and inductance of the system. This phenomenon is especially encountered in high-frequency applications. Since the system operates within a range of 60-1000 Hz, the overall impedance of the system is quite high. Strategies to overcome this impedance are studied. Due to the highly inductive nature of the circuit presented, the use of a capacitor to counteract the effect of inductance are emphasized in this study. The results of the addition of a capacitor in parallel to the levitator circuit are described. ANSYS Maxwell and PartSim (a SPICE simulator engine) are used to conduct this analysis.
