The purpose of this research is to develop an electromagnetic pump system for electrification of casting applications, and this paper reports the evaluation results of drive characteristics considering the electromagnetic fluid elements or time harmonics that are inverter driven. First, considering the electromagnetic fluid elements, an alternative experiment is proposed using oil mixed with aluminum powder, and the results of the lift speeds driven at variable frequencies by a pure sinusoidal power supply are demonstrated. Then, considering the time harmonics driven by a pulse-width modulation control inverter, another experiment is performed through aluminum pipe lifting. The experimental results for lift speed when the combination of carrier frequency and excitation frequency are changed is reported. These results clarify the effects of the two factors on the lift speed.
