ELECTROMAGNETIC ACTUATOR, THE MAGNETIC ACTUATOR MANUFACTURING METHOD AND LIGHT POLARIZER USING THE ELECTROMAGNETIC ACTUATOR

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic actuator which reduces its power consumption, improves its energy efficiency and enlarges its generating force by reducing leakage of magnetic flux, the magnetic actuator manufacturing method and a light polarizer using the electromagnetic actuator. SOLUTION: The electromagnetic actuator is constituted of a stator which is composed of a stator core on which coil is wound and a moving element which is composed of a moving element core on which a coil is wound. The stator core and the moving element core are magnetically connected through an air gap, and the moving element is displaced against the stator by energizing at least either of a coil wound on the stator core or on the core of the moving element core through a current applying means.
