Abstract:
1. A stator comprising: a core formed of ferromagnetic material, the core having a plurality of teeth arranged circumferentially about an axis; a plurality of wire coils, each of the wire coils being wound around a respective one of the teeth; at least two non-wound sections of wire extending from the plurality of wound wire coils; at least two sheathed electrical conductors, each of the electrical conductors being electrically connected to a respective one of the non-wound sections of wire in a manner forming an electrical junction; and first and second retaining members that are secured to each other, the first and second retaining members substantially enclosing a cavity that extends about a substantial portion of the core, the cavity housing the electrical junctions and at least portions of the non-wound sections of wire, each of the electrical conductors being secured to the first retaining member in a manner defining first and second portions of said electrical conductor, the first portion of each of the electrical conductors operatively connecting the respective electrical junction to the second portion of said electrical conductor, at least part of each of the second portions of the electrical conductors being external to the cavity, the first retaining member being an electrical insulator and comprising a plurality of teeth arranged circumferentially about the axis, the teeth of the first retaining member being aligned with the teeth of the core, each of the wire coils being wound around a respective one of the teeth of the core and a corresponding one of the teeth of the first retaining member, the first retaining member comprising a ring-shaped channel, the second retaining member comprising a cap, the cap and channel binding the cavity.
