In resent years, a sinusoidal excitation equipment, that is, a two-phase induction motors fed by AC and DC voltage-source have been employed in angular accelerating calibration of the angular accelerometer, the measuring device of moment of inertia, cleaning and polishing device etc. as a excitation equipment.
Generally, the excitation equipments are required to have larger alternating torque.
Previously we have derived the practical equation to calculate the alternating torque of excitation equipments.
In this paper, at first, for the sinusoidal excitation equipments that is, two-phase induction motor fed by AC and DC voltage-source, the relation among the equipment circuit parameters and an alternating torque characteristics are investigated numerically. And, the influence of equivalent circuit parameters on the alternating torque characteristics and it's tendency are clarified.
Secondly, a guideline for the excitation equipment design that can be generate larger alternating torque are presented by using the equivalent circuit parameters.
Lastly, in order to verify the validity of our new strategy, the trial excitation equipments which is designed by the various redesign condition has been compared with the previous excitation equipments.
