Document Type and Number:
Japanese Patent JPH07123667
Kind Code:
A
Abstract:
PURPOSE: To secure magnets and auxiliary poles to a yoke and, further, obtain a stable holding force regardless of the variations in dimensions of the components.
CONSTITUTION: The stator 1 is composed of a yoke 2 and a plurality of permanent magnets 3 and auxiliary poles 4 provided on the inner circumference of the yoke 2. Holders 5 made of elastic material are fixed to the yoke 2. Protrusions are provided on the holders 5 so as to press the auxiliary poles 4 on the positions away from their centers.
