Abstract
A bobbin is provided for a stator of an electromagnetic device. The bobbin has two spaced-apart walls around which copper windings are wound. The spaced-apart wall arrangement reduces the material and space occupied by the bobbin, allowing for additional copper windings.
Claims16
A component for a stator, comprising:
- a bobbin including:
- a first radial end section;
- a second radial end section spaced apart from the first radial end section in a radial direction;
- and
- a first wall and a second wall extending radially between the first and second radial end sections, the first wall defining a width, wherein the first wall and the second wall are separated in one of an axial direction and a circumferential direction;
- and
- a coil wrapped around the bobbin, the coil being located in a winding envelope defined by the bobbin, wherein the coil passes from the first wall to the second wall without any portion of the bobbin therebetween.

A stator for an electromagnetic device, comprising:
- a stator pole extending radially;
- a bobbin including:
- a first radial end section,
- a second radial end section spaced apart from the first radial end section in a radial direction, and
- a first wall and a second wall extending radially between the first and second radial end sections, the first and second walls each having a thickness in the axial direction;
- and
- a winding of conductive coil wrapped around the bobbin, wherein a portion of the winding is spaced from the stator pole by a clearance distance.
