<p>PURPOSE:To reduce the vibration of a stabilizer and suppress the noise by forming a side of an E-shaped yoke to have a circular arc cross section. CONSTITUTION:An E-shape yoke 2 which is to be provided to an I-shape core 1 is formed to have semi-circular arc shape over its whole length and when two E-shape yokes 2 are provided facing each other with the I-shape core 1 in between they form a circle. moreover, if the side of the yoke 2 is formed to have a circular arc cross section the better effect can be expected. With this constitution, when an alternating current flows in the I-shape core 1 and generates an alternating magnetic field, a resultant force of the forces generated in the E-shape yoke 2 and acting to the direction of the I-shape core 1 is balanced at the center of a circle made by the E-shape yokes so that the vibration generated in the E-shape yokes are eliminated and generated noise is suppressed significantly.</p> |
