ABSTRACT:
A motor includes a base, a stator mounted to the base, a rotor rotatably coupled to the base, and a balancing member. The rotor includes a permanent magnet having a first magnetically conductive face with a first width in a radial direction. The balancing member includes an upper surface facing the permanent magnet. A magnetically conductive section is formed between the upper surface and the first magnetically conductive face. The balancing member further includes a magnetically attracting portion in the magnetically conductive section. The magnetically attracting portion includes a second magnetically conductive face having a second width in the radial direction. The second width is not greater than the first width. A magnetically attracting spacing is formed between the first and second magnetically conductive faces and in a range of 0.2-1.5 mm.
