Abstract

PURPOSE:To build up such a constitution as no change will occur to a magnetic neutral point by the change of polar dimensions, by elastically holding the sides of each pole in an elastic holder. CONSTITUTION:Holding fittings 3 composed of an elastic member are fixed to arrange at equal intervals along the inside circumference of a yoke 2. Then, by matching their axial end faces, an auxiliary pole 4 and a permanent magnet 5 are forcibly fitted into a holding fitting 3. The auxiliary pole 4 and permanent magnet 5 are pressed to be positioned at a magnetic neutral point determined without regard to the unequality of dimension tolerance of parts and with this tensile force a pole 6 is pushed to the inside circumference of the yoke 2 to fix. A cylinder section 7a of a pole cover 7 is then inserted into the inside circumference of the pole 6. After that, a cylindrical elastic body such as rubber, etc. is inserted inside the cylinder section 7a and pressed. The cylinder section 7a is tightly fitted to the inside circumference of the pole 6, while th. cylinder section is so forcibly fitted and deformed as to project a part 7a, of the cylinder section 7a to the space S side and with the pole cover 7 the pole 6 is clamped inside the yoke 2 and fixed.
