ータ。 At least one hollow cylindrical or flat permanent magnet magnetized in the thickness direction is opposed to a rod-shaped or flat center yoke at a constant interval so that the same poles of the permanent magnets face each other. An outer yoke is provided outside the permanent magnet, and is magnetically shorted to the center yoke to form a magnetic circuit. A drive coil is arranged to surround the center yoke, and a current is passed through the coil. A voice coil type linear DC motor that utilizes the reciprocating driving force generated when the drive coil is operatively connected to a movable table.
