Abstract

PURPOSE: To readily determine the direction of an electric current in a moving-coil type linear motor by providing two coils having half the width of a stator magnet at a rotor and mounting a detecting element at the one coil end of the two coils to control the supply current thereto.
CONSTITUTION: Permanent magnets 1A, 1B which are alternatively magnetized in thickness direction are arranged in two lines. A rotor 8 having two coils 7A, 7B each including half the width of the permanent magnet 1 is provided oppositely to the permanent magnets on a center yoke 3. A magnetic detecting element 11A is provided between the coils 7A and 7B of the rotor 8, and a magnetic detecting element 11B is also provided, for example, at the end of the one coil 7B. The outputs 12A, 12B of the respective elements 11A, 11B and a drive direction signal 15 are supplied to a drive circuit to determine the coil to be energized and the direction of the current to be applied.
