摘要:
A vacuum cleaner includes a housing adapted for movement on a subjacent surface and a nozzle defined in the housing, the nozzle having an opening. A brushroll tube, having first and second ends and a longitudinal axis, is rotatably mounted to the housing adjacent the nozzle opening. At least one cleaning element protrudes from the brushroll tube. A shaft is located in the brushroll tube and extends along the longitudinal axis thereof. A stator is rigidly mounted on the shaft. A cylinder surrounds the shaft and the stator and is spaced therefrom. The cylinder is rigidly connected to the brushroll tube. A permanent magnet rotor is fixedly mounted to an interior surface of the cylinder. The permanent magnet rotor overlies and is coaxial with the stator and is spaced therefrom. The rotor and stator form a motor for rotating the brushroll tube wherein the rotor is driven by changes in induced magnetic fields in the stator.
