Abstract: An outer rotor motor includes an inner stator and an outer rotor. The inner stator includes a stator frame and a stator unit mounted to the stator frame. The outer rotor includes a shaft and a rotor unit fixed to the shaft. The stator frame is integrally formed from plastic as an integral structure and comprises a base and a hub extending from the base, the hub forms a chamber therein, supporting components are installed in the chamber, and the shaft extends into the chamber and supported by the supporting components such that the shaft is rotatable relative to the stator frame. In the present invention, the stator frame has an integral structure made of plastic which simplifies the structure of the motor and reduces the cost of the motor. The present invention further provides a vacuum cleaner that employs the motor.

Abstract: A rotor includes a magnet yoke and a number of permanent magnets. The magnet yoke defines a number of accommodating slots therein, and each of the permanent magnets is received in one of the accommodating slots. An elastic member protrudes from the magnet yoke towards each of the accommodating slots, the permanent magnets are inserted in the corresponding accommodating slots, and the elastic members are bent and abut against the permanent magnets. A motor and a power tool include the rotor are also disclosed.

Abstract: An outer rotor for a brushless motor has an end plate; a shaft fixed to a rotary center of the end plate; and an annular rotor core having one end connected to the end plate. A plurality of connecting bars connect the rotor core to the end plate. Permanent magnets are fixed to an inner surface of the rotor core. The end plate has an outer diameter equal to or less than the outer diameter of the rotor core. The end plate has a base plate, an annular sidewall, and a plurality of fan blades interconnecting the base plate and the sidewall. There are openings between the fan blades. The end plate is insert molded to the shaft and the connecting bars.

Abstract: An electronic device includes a housing defining an opening; a sealing assembly including a main body and a sealing element mounted on the main body; the sealing element comprising a first sealing portion and a second sealing portion; the main body having a compartment, a hole and a first mounting hole; the hole and the first mounting hole respectively defined at opposite ends of the main body; and the hole aligned with the opening; and an interface mounted to the first mounting hole. The first sealing portion and the second sealing portion are both made of resilient material, the first sealing portion located between the housing and the main body to seal a first gap occurring between the housing and the main body, and the second sealing portion surrounding an inner surface of the first mounting hole to seal a second gap occurring between the interface and the main body.

Abstract: A fastening structure for a portable electronic device includes a main housing and a frame. The main housing defines a slot. A protrusion and a block are formed at two opposite sides of the slot. The frame includes a tab. The tab defines a locking hole. The block pushes the tab toward the protrusion to allow the protrusion to be latched in the locking hole for connecting the frame to the main housing.

Abstract: An elastic sheet structure includes an elastic body and a conductive body. The elastic body is capable of elastic deformation, and the conductive body includes a main body, a first elastic arm, and a second elastic arm. The main body is installed into the elastic body; the first elastic arm and the second elastic arm are connected at opposite sides of the main body and extend out from two opposite ends of the elastic body. The first elastic arm is capable of electrically connecting to ground to conduct away static electricity through the second elastic arm, the main body, and the first elastic arm. An electronic device employing the elastic sheet structure is also described.
