形リニアパルスモータ。 Two rows of two primary magnetic pole surfaces are formed on the secondary scale tooth surface with teeth having the same pitch as the secondary scale tooth but with a 1/4 pitch deviation. In a thin linear pulse motor, the magnetic pole surfaces of each row are connected by magnetic path forming iron cores extending parallel to the magnetic pole surfaces in opposite directions, and each iron core is equipped with an excitation coil. , a permanent magnet attached to each magnetic pole on the primary side and an excitation coil are arranged in parallel, and the magnetic field of each permanent magnet is alternately increased or decreased by the magnetomotive force generated by excitation of the excitation coil. Features a thin linear pulse motor.
