Abstract
There is provided a stator and a method of making the same. For example, there is provided a stator that includes a single piece yoke and a set of teeth mounted on an inner surface of the single piece yoke. Each tooth is pre-wound with a coil and includes a tail portion configured to secure the tooth on the inner surface. Furthermore, at least two teeth of the set of teeth are mounted on the single piece yoke at a slot opening distance of less than about 35%.

A stator, including:
- a single piece yoke;
- and
- a set of teeth mounted on an inner surface of the single piece yoke, each tooth being pre-wound with a coil and including a tail portion configured to secure the tooth on the inner surface;
- wherein at least two teeth of the set of teeth are mounted on the single piece yoke at a slot opening distance of less than about 35% of an arc length extending from a center of one of the at least two teeth to a center of the other one of the at least two teeth;
- and
- a member disposed between at least one tooth of the set of teeth and an un-wound tooth of the set of teeth, to provide compression of a coil on a side of the at least one tooth, wherein the member is non-metallic.
