Title: Linear stepping motor
Inventor: YAMASHITA TORU
IPC: H02K41/03
Filed: 1987-01-30
Abstract: PURPOSE:To prevent the deviation of a position due to a thermal displacement between a head, connected to a movable piece by the thermal displacement, and a track on a recording medium, by a method wherein the thermal expansion coefficients of the movable piece and the magnetic pole teeth of a stator are equalized to the thermal expansion coefficient of the recording medium. CONSTITUTION:A linear stepping motor consists of a stator 20 and a movable piece 30 and a head 4, attached to the tip end of a head supporting part 5 whose one end is connected to the movable piece 30, is abutted against a track on a recording medium 6 to transmit and receive an information. Here, magnetic pole teeth are formed on the stator 20 and the movable piece 30 by laminating teeth parts and groove parts alternately, however, the composite thermal expansion coefficient of the teeth parts and the groove parts are equalized to the thermal expansion coefficient of the recording medium 6. According to this method, the amount of stepping of the movable piece 30 becomes equal to a distance between the tracks on the recording medium 6 after a thermal displacement whereby the deviation of a position will never be generated by the thermal displacement between the head and the track.
