Abstract
A laminated core for a motor includes a plurality of core members made of magnetic material and which are laminated to form laminated core members; insulating layers formed on the surfaces of the laminated core members, and a wire wound on the insulating layer of the laminated core members, wherein the insulating layers are respectively formed on the core members located on the upper and lower sides of the laminated core in the laminate direction.
Claims8
A laminated core for a motor, comprising:
- a plurality of core members, made of magnetic material, which are laminated in a laminate direction to form laminated core members, said laminated core members including outer core members located at opposite end sides in the laminate direction and inner core members disposed therebetween;
- and
- insulating layers formed on surfaces of the laminated core members,
- wherein the insulating layers are respectively formed on the outer core members located on the opposite end sides of the laminated core in the laminate direction but are not formed on the inner core members, and
- further wherein each of the outer core members has a width that is larger than a width of the inner core members.
