摘要： A disk-shaped magnet attached to a rotary shaft is circumferentially segmented into a plurality of segments which are magnetized to form driving magnetic poles. A plurality of velocity detecting magnetic poles are also arranged on the disk-shaped magnet concentrically to the driving magnetic poles. The number of the velocity detecting magnetic poles is larger than the number of the driving magnetic poles to increase the frequency of an output signal of a velocity detecting coil which interlinks with the velocity detecting magnetic poles so that a response speed of a velocity control circuit is increased.

摘要： A linear motor of moving-coil type is disclosed, in which a multi-phase moving coil includes a plurality of flat coil units each not wider than the longitudinal length of a permanent magnet making up a stationary part divided by the number of coil phases, the flat coil units being arranged successively in the same plane with central parts not adjacently overlaid one on the other. The central parts of the moving flat coil units have a thickness equivalent to a single phase in spite of the multiple phases of the moving coil. Thus a great electromagnetic force is generated, and at the same time a high propulsive force is obtained with the magnetic flux density not reduced in the gap accomodating one phase of coils alone.
