Patent number: 8587172Abstract: A sensor fastening method and a sensor fastening frame for use therewith are provided. The sensor fastening frame is coupled to a motor stator of a brushless motor having distributed coils and extends over the distributed coils to allow the sensor fastening frame to rotate about the axle of a motor rotor, without interference with the distributed coils. At least a sensor is fastened in position to the sensor fastening frame proximate to one end of the axle of the motor stator for positioning the sensor to detect magnetic field variations of the motor rotor.Type: GrantFiled: January 23, 2009Date of Patent: November 19, 2013Assignee: System General CorporationInventors: Shih-Jen Yang, Hung-Sen Tu, I-Hsing Chen, Chen-Chia Yang, Chung-En Chen

Patent number: 8508091Abstract: An end cover adapted to engage with an end surface of a spindle of a motor rotor is proposed for securely coupling to the spindle with a plurality of permanent magnets disposed around the peripheral wall of the spindle. The end cover has a first surface facing an end surface of the spindle and an second surface opposing to the first surface, which is formed with a plurality of inserting slots indentedly disposed around the rim thereof and corresponding to the permanent magnets for coupling the ends of the permanent magnets, thereby securely fastening each of the permanent magnets to the spindle of the motor rotor. Further, the present invention further provides a motor rotor having the end covers described above.Type: GrantFiled: December 30, 2008Date of Patent: August 13, 2013Assignee: System General CorporationInventors: Shih-Jen Yang, Hung-Sen Tu, I-Hsing Chen, Chen-Chia Yang, Chung-En Chen

Publication number: 20120043843Abstract: A motor rotor includes an annular body and a positioning protrusion installed on an inner lateral surface of the annular body. A magnetic body may be positioned by propping its lateral surface against the positioning protrusion, without the use of additional jigs. Therefore, the time needed to assemble the magnetic body to the annular body is saved, and the manufacturing cost of the whole motor is reduced.Type: ApplicationFiled: August 19, 2010Publication date: February 23, 2012Applicant: SYSTEM GENERAL CORPORATIONInventors: Yung-Sheng Wu, Hung-Sen Tu, I-Hsing Chen

Patent number: 7888835Abstract: A rotating shaft disclosed by the present invention includes a plurality of bumps spacedly formed along an outer circumferential surface thereof. The bumps are each formed with two engagement portions extending outwardly and bilaterally and a deformation space therebetween. The engagement portions undergo resilient deformation toward the deformation space when subjected to a force, thus providing stable engagement with a magnetic body, protecting the magnetic body from cracks and damages during assembling, and enhancing yield. The present invention further discloses a motor rotor having the above-described rotating shaft.Type: GrantFiled: October 1, 2007Date of Patent: February 15, 2011Assignee: System General CorporationInventors: Shih-Jen Yang, Hung-Sen Tu, I-Hsing Chen, Chen-Cha Yang

Publication number: 20100109465Abstract: A motor structure and a fan are provided. The motor structure includes a shaft, a motor control panel, a stator, a rotor and a motor housing. The motor control panel has a first fastening portion and is engageable with the shaft. The stator has a second fastening portion coupled to the first fastening portion so as to fasten the motor control panel to the stator, thereby reducing the overall size and saving costs of materials. The rotor corresponds in position to the stator and is pivotally connected to the shaft. The motor housing is pivotally connected to the shaft and encloses the shaft, the motor control panel, the stator, and the rotor. The fan includes the motor structure and a fan blade element.Type: ApplicationFiled: February 26, 2009Publication date: May 6, 2010Applicant: SYSTEM GENERAL CORPORATIONInventors: Shih-Jen Yang, Yung-Sheng Wu, Hung-Sen Tu, I-Hsing Chen, Chen-Chia Yang
