Resonance control method to suppress the self and mutual inductances of a 3-phase magnetic navigation system for fast drilling motion of micro helical robots

We developed a resonance control method to generate high-speed rotating magnetic field in three-phase navigation system composed of three electromagnets. The proposed calculates the amplitudes and phases voltages, while capacitances suppressing self mutual inductances electromagnets keep currents magnitude constant, even if frequency increases. Finally, we prototyped variable capacitor module validate effectiveness experimentally.
