Because of its light weight, thinness, and large power per weight ratio, it has promise as a small-size, high-power motor in the future. Of the three types of driving method that had been formerly developed for the motor, the single frequency method, which drives the motor by applying a three-phase ac voltage to the electrodes of the motor, is the most useful since it needs the least number of phases of power supply. However, this method has problems with operation at very low speed such as 10 μm/s. In order to solve such problems, this paper proposes a novel add-on operation method. In the new method, called modulation drive, the excitation voltage to each phase of the electrodes is amplitude-modulated by a carrier signal with higher frequency before being applied to the electrodes. In tests regarding the single frequency method, the modulation drive successfully drove a motor with typical power operational amplifiers that were boosted by transformers with ferrite cores, and eliminated the force degradation at low drive speed. Additionally, the force generation of modulation was analyzed, and the results agreed very well with the experimental results. © 2000 Scripta Technica, Electr Eng Jpn, 131(4): 78–84, 2000 Citing Literature Volume131, Issue4June 2000Pages 78-84 RelatedInformation
