Title: IMPROVEMENTS IN STARTER MOTORS
Abstract:
A framework is disclosed for holding magnets to provide a stator for an electric motor, in particular for a starter motor. The framework is adapted to removably receive, retain and space apart a plurality of magnets within the framework to form a tubular magnet array and provide said stator. The framework may provide a stator which is easier to assemble and more reliable than known stators. The framework provides a central aperture for receiving a rotor armature of said electric motor. The framework is arranged to be slidably inserted or removed from a housing of said electric motor. A frame portion, a stator, an electric motor, a vehicle drive assembly and a method of assembling an electric motor are also described. A brush housing comprising a plurality of passages for slidably retaining brushes and comprising a plurality of bias housings, and a brush assembly comprising the brush housing are also described.
