摘要：
The invention provides a magnetic-positioning motor having a magnetic element or magnet disposed at the interior center of a rotor, so that attractive force between the magnetic element and a metallic stator can maintain a rotor at a predetermined position during fan rotation. Additionally, a magnetic element or magnet can be placed on a stator, so that attractive force between the magnetic element and a metallic rotor can maintain a rotor at a predetermined position during fan rotation to reduce vibration, flotation and friction between the shaft and bearing under high speed operation.
