Abstract

The invention discloses a motor and a rotor thereof. A central opening is formed in central portions of a plurality of first laminations on one end in an axial direction of a rotor core body. A rotorshaft passes through the central opening without contacting the first laminations. At least part of the bearing of the motor rotor is positioned in the central opening of the first lamination. The rotor has a space capable of containing the bearing. Products using the motor and the rotor thereof are light and miniaturized.

Description

technical field [0001] The present application relates to a motor and its rotor, and in particular to the technology of forming the core body of the rotor by stacking a plurality of laminations. Background technique [0002] Motors are widely used in electrical appliances or various machinery as a power source. The motor includes components such as a shell, a stator, and a rotor. The stator is fixed to the shell, and a plurality of ferromagnetic laminations are stacked to form the core of the rotor. The rotor is supported on the shell by bearings. However, due to performance requirements such as the required driving torque, the size of components such as bearings and rotors must be large enough, so it is difficult to reduce the overall size of the motor and meet the requirements of miniaturization of the motor. [0003] Therefore, it is necessary to improve to overcome the technical problems existing in the prior art. Contents of the invention [0004] This application m...
