A motor includes a rotor, the rotor includes a rotor iron core, a first end cover, and a second end cover, and the first end cover and the second end cover are respectively connected to two ends of the rotor iron core. The first end cover is provided with a liquid inlet channel, the rotor iron core is provided with a liquid flow channel, and the first end cover or the second end cover is provided with a liquid outlet channel. The liquid inlet channel connects the liquid flow channel and space outside the rotor, the liquid outlet channel connects the liquid flow channel and the space outside the rotor, and an outlet of the liquid outlet channel faces a stator winding. Solutions of the embodiments can reduce processing costs while ensuring heat dissipation reliability of the rotor of the motor.

Motor, motor cooling system, and electric vehicle

A motor rotor includes a wound rotor comprising a rotating shaft, a rotor core, and a plurality of rotor coils. The rotor core is fixedly sleeved on the rotating shaft, a plurality of winding holes surrounding the rotating shaft are provided at intervals on the rotor core, each winding hole penetrates through two ends that are of the rotor core and that are disposed in an axial direction, each rotor coil is wound on hole walls of two adjacent winding holes, and two adjacent rotor coils share one winding hole. A gap is formed between two adjacent rotor coils, a first shaft hole is formed on the rotating shaft, the gap is configured as a first heat dissipation channel connected to the first shaft hole, and the first heat dissipation channel is used for inflow of coolant in the rotating shaft.

The present application provides internet browsing especially a three dimensional webpage browsing methods and systems by using the movement of a computing device with a display. By moving the computing device, a user changes the location and the orientation of the computing device, and thus interacts with at least one information item in a first web page. The computing device measures the location difference and the orientation difference between the computing device and the information item, and determines whether each of the location difference and the orientation difference is within a threshold, respectively. If both the location and orientation differences are within the threshold for a predetermined time, the user is directed to a second web page.
