Title:
DISC-SHAPED ROTARY ARMATURE
Document Type and Number:
Japanese Patent JPS5826540
Kind Code:
A
Abstract:
PURPOSE:To reduce the moment of inertia as well as to improve the responsiveness of the titled armature by a method wherein, in the disc-shaped armature on which a coil is arranged on both surfaces of a discoid insulated substrate, the width of the conductor of the outside loop part whereon a double-side coil will be connected is made smaller than the other part. CONSTITUTION:When a disc-shaped armature coil 8 is formed by radially arranging rectilinear coils 9 and 9' on both surfaces of the disc-shaped insulated substrate 1 and by performing double-sides connection using the outside loop parts 10 and 10' provided on the external circumference, the conductor width (a') of the coils 10 and 10' on the outside loop part is formed narrower than the conductor width (a) of the rectilinear coil 9 and the coil 11 of the inside connecting part. Accordingly, as the weight of the external circumference is reduced, the moment of inertia can be reduced as a whole.
