Motor for rotary brush |
摘要 |
An electric motor construction and method particularly adapted for integration in rotating final drive members. The motor includes a hollow armature assembly rotatably supported about a permanent magnet stator. The armature assembly includes a winding preferably fabricated by printed circuit techniques in the form of flat conductors clad on a flexible dielectric sheet rolled into a tube and a soft magnetic tube circumferentially surrounding the winding to provide a structural support and a heat sink for the winding and a flux return path for the poles of the permanent magnet stator. In the preferred embodiment, the motor is integrated in the cleaning brush of a vacuum sweeper unit.
