Abstract: The present invention discloses a stator and rotor fixture of an electric motor, and the fixture includes a frame, a stator and a rotor, both contained in the frame. The center of the stator installs a sheathing portion, and the sheathing portion has an embedding groove extended inwardly from an internal lateral side of an opening disposed at a free end of the sheathing portion, and a bearing sheathed into the sheathing portion. The center of the rotor installs an axle, and the axle is sheathed into the bearing, and the rotor has a latch extended outward and corresponding to the embedding groove, such that the corresponding embedding groove and latch fix the stator and the rotor securely together, so as to facilitate installing and removing an electric motor.

Abstract: The present invention discloses a structure for fixing a fan with a computer casing, and the structure includes a casing, an opening with a specific area on any side of the casing, and a locking hole proximate to each distal edge of the opening. The interval between two adjacent locking holes is equal to 170±5 mm, such that if a large fan is installed at the opening, a locking member can be secured directly to the corresponding locking hole, not only saving the time of drilling holes, but also resulting no increased area of the casing. The fan can be installed onto the casing for discharging any heat source produced by each component on a motherboard in the casing quickly, so that the heat will not remain in the casing, or drawing outside air into the casing to cool each component in the casing rapidly.
