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.

摘要： A heat sink for coolers is provided. The heat sink contains a heat conductive element, a heat dissipating shell covering over the heat conductive element, and a plurality of heat dissipating fins installed on the heat dissipating shell. The heat conductive element includes a heat conductive plate and a heat conductive block installed at the center thereof. The area of the bottom surface of the heat conductive block is greater than that of the topmost surface thereof. When the lower surface of the heat conductive plate is in contact with a device that needs heat dissipation, the heat conductive block increases the heat conducting volume at the center of the heat conductive plate, so that the heat produced by the device can be released at an optimal rate.

摘要： The proposed method for starting a motor having a stator, a rotor, a winding and an asymmetrical air gap, comprising the steps of: (a) exciting said winding with a current impulse such that said stator generates a magnetic field and going to one of steps (b) and (d); (b) driving said rotor to rotate in a first direction if a polarity of a portion of a specific tooth of said stator close to said air-gap and a polarity of a specific magnetic pole of said rotor corresponding to said tooth are opposite; (c) stopping said current impulse at a specific moment such that said rotor is rotated in a second direction by a cogging torque and going to step (f); (d) driving said rotor to rotate in a first direction if a polarity of a portion of a specific tooth of said stator close to said air-gap and a polarity of a specific magnetic pole of said rotor corresponding to said tooth are the same; (e) stopping said current impulse at said moment such that said rotor is rotated in a second direction by an inertia; and (f) detecting a back electromotive force (BEMF) in said winding when said rotor is rotated such that said motor is controlled for commutating according to said BEMF. The provided method overcomes the drawbacks of failing to position the rotor due to the oscillation of the rotor in the prior art.
