CENTER YOKE AND SHORT RING, AND CLOSE-CONTACT METHOD THEREFOR IN VCM LINEAR MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a center yoke and a short ring with high performance efficiency, and a close-contact method therefor in VCM linear motor. SOLUTION: There is provided the center yoke formed with a curved surface having different curved surface angles at the upper and lower ends on both sides in the shorter direction of the center yoke and a short ring and the short ring into which the center yoke of hollow cross section and rectangular side surface is pressed. The center yoke is formed with an even contact surface and an uneven contact surface in the short ring thereby improving close contact between the center yoke and the short ring.
