ABSTRACT:
A moving-coil linear motor is formed with a stator means forming a guide and having a permanent magnet array having opposite poles alternately at constant intervals in longitudinal direction of the stator means, and a mover means mounted on the stator means for being movable through an electromagnetic force along the stator means, the mover means having three-phase moving coils wound in bipolar system on cores U-shaped in section. Positive and negative voltages are alternately applied through brushes to the moving coils of the mover means, while its U-shaped cores are opposed to the permanent magnet array, disposing the array between both leg portions of the U-shaped cores, with the magnetic efficiency of the motor thereby remarkably improved while sufficiently effectively minimizing the size.
