Rotor cover body structure and motor

The utility model relates to a rotor cover body structure and a motor. The rotor cover body structure comprises a rotor support, a rotor shell and a magnet, one end of the rotor support is embedded in the rotor shell, a plurality of installation columns are arranged on the rotor support at intervals, and the installation columns and the inner wall of the rotor shell form a containing cavity used for containing the magnet. The rotor support is matched with the rotor shell, then the magnet is placed in the containing cavity, the complex process that a traditional brushless motor outer rotor cover body structure is formed through stretching or plate rolling is omitted, the rotating shaft is installed at the center position of the rotor support, assembling is easy and convenient, concentricity is good, and outer circumference jumping is small during rotation. And the rotor shell is formed by laminating and riveting a plurality of silicon steel sheets, so that the requirements of large cogging torque, high heat di
