Title:
FIXING METHOD OF COIL
Document Type and Number:
Japanese Patent JPS58195118
Kind Code:
A
Abstract:
PURPOSE: To enable simple fixing of coils which detect the change in the magnetic flux quantity in a magnetic yoke by inserting a leaf spring between the adjacent coils in order to fix the coils to the magnetic yoke.
CONSTITUTION: Coils 2 for detecting magnetism are inserted to an annular magnetic yoke 1 of which the figure using a two-pole magnet is shown. As a magnet 4 inserted at the center of the yoke 1 rotates, the magnetic flux quantity in each yoke of the yoke 1 changes. The coils 2 are so arranged that two pieces of the coils are pressed to the outside circumferential side and are thus fixed when a leaf spring 3 is inserted between the two adjacent coils. The spring 3 is made to the shape as shown in the figure.
