| 20100231097 | Micro-Motor - A micro-motor includes a base, a rotor and a retaining member. The base includes an axle tube. The rotor includes a rotary member and a support member arranged between the rotary member and the base. The rotary member has a central hole where the axle tube of the base extends. The retaining member is mounted on the base and surrounds the rotor. One end of the retaining member, which doesn't couple to the base, extends towards the axle tube to form a retaining portion. The retaining portion is within a rotational area of the rotor in an axial direction of the axle tube. The rotor is arranged between the retaining portion and the base. Accordingly, the retaining member can retain the rotor to prevent departure of the rotor from the axle tube of the base and the central structure of the micro-motor is effectively simplified. | 09-16-2010 |

Support bases are fixed to the rotor, and are interposed by the rotor core. A locking member coupled to the first framework is configured to contact the first support base. A locking member coupled to the second framework is configured to contact the second support base. The rotor is fixed by the locking members contact with the support bases. | 03-15-2012 |
| 20120206022 | ELECTRIC MOTOR HAVING AN END FRAME - An electro-dynamic machine including a rotor shaft extending along an axis and a bearing rotatably supporting the rotor shaft for rotation about the axis. An inner housing has an outer surface and defines a bearing bore. The bearing bore receives and supports the bearing. An outer housing surrounds the inner housing. A plurality of non-radial ribs extends from the outer housing to the inner housing. The non-radial ribs are coupled to the inner housing substantially tangential to the outer surface. | 08-16-2012 |
| 20140001925 | MOTOR ASSEMBLY | 01-02-2014 |
| 20150108876 | INNER-ROTOR-TYPE MOTOR - An inner-rotor-type motor, includes four outer surface portions flush or substantially flush with the motor outer surface of the core-back portion provided in the frame portion of each of the two insulating members of the insulator to secure electrical insulation between the stator core and the coil. The outer surface portions of the frame portion of each of the insulating members are inserted between the leg portions of four corners of each of the cover members attached to the axial opposite sides of the stator core. In this state, the cover members are attached to the stator core. The inner-rotor-type motor makes it possible to easily and cost-effectively manufacture a cover member without impairing the dust-proofness of the interior of the motor and greatly improves ease of assembly. | 04-23-2015 |
| 310402000 | Having particular frame- or core-mating feature (e.g., keyed, projection/recess) | 2 |
| 20110037352 | MOTOR END CAP POSITIONING ELEMENT FOR MAINTAINING ROTOR-STATOR CONCENTRICITY - A motor is provided with a set of end cap guides on the ends of a stator winding assembly to plot the placement of end caps into the correct placement relative to the stator winding assembly so that the rotor assembly is maintained concentric with the stator. The end cap guides may be rings fitting within the winding insulators on the ends of the stator stack or may be integrated as guide segments with the winding insulators to outline an interrupted cylindrical inner surface coinciding with the inner diameter of the stator winding assembly. The guides allow proper positioning of the rotor assembly without increasing the stator stack length. | 02-17-2011 |
| 20130026887 | ELECTRIC APPARATUS WITH STATOR CORE - An electric apparatus with high performance and high rigidity is provided. Annular positioning stepped portions are formed at respective outer peripheral corner portions of both end portions of a stator core to extend entirely circumferentially of the stator core. An annular positioning projecting portion is formed at a first end bracket to be entirely fitted with one of the annular positioning stepped portions of the stator core. An annular positioning projecting portion is formed at a second end bracket to be entirely fitted with the other annular positioning stepped portion of the stator core. | 01-31-2013 |
| 310406000 | Cup-shaped end shield connected to another end shield | 1 |
| 20110175493 | FAN - A fan includes a bracket, a stator, a rotor, and a slanting portion. The bracket includes a tray, and a frame circling the tray. The stator is mounted to and circled by the frame. The rotor includes a shaft rotatably mounted to the stator, and a shell coupled to the shaft. The shell covers the stator, and the shell and the tray of the bracket cooperatively enclose the stator. An assembly clearance is formed between a bottom end of the shell and a top surface of the tray. The slanting portion circles the tray and extends down from the bottom end of the shell, slanting away and spaced from the tray. | 07-21-2011 |
