Title:
STATOR YOKE AND RADIAL GAP TYPE MOTOR
Document Type and Number:
Japanese Patent JP2006149007
Kind Code:
A
Abstract:
To provide the form of a yoke where the efficiency of magnetic flux generated in a coil within a motor rises.
In a stator yoke 13 which is used for a radial gap type motor 10 and consists of a hollow magnetic substance where the internal perimeter 13a is polygonal in cross section and the plane part 13a-1 of the internal perimeter 13a serves as a coil mount, the periphery 13b is polygonal in cross section, roughly analogous to the internal perimeter 13a, thereby equalizing its sectional thickness T in radial direction.
