<p>A motor comprising a combination of a plurality of sets of coils and permanent magnets, wherein the sets of coils are supplied with exciting signals from a drive circuit so as to be excited to opposite poles alternately, the permanent magnets are so constructed that a plurality of magnetic pole elements are disposed so as to act alternately as opposite poles, the above drive circuit is so constructed as to supply exciting signals having a specified frequency to the sets of coils and relatively move the sets of coils and the permanent magnets by the magnetic attraction/repulsion between the coils and the permanent magnets, and the drive circuit is so constructed as to supply to the sets of coils waveform signals equivalent to the pattern of a reverse voltage produced in the sets of coils according to the relative movement between the sets of coils and the permanent magnets.</p> |
