Abstract

A rotor for an inner rotor motor is provided for solving the problem of easy loosening between a rotating shaft of a conventional motor and a permanent magnet. The rotor of the inner-rotor motor of the present invention comprises: a rotating shaft having at least one first positioning portion; a permanent magnet disposed on the rotating shaft, the first end of the permanent magnet having at leastone first joint portion, the at least one first joint portion is combined with the at least one first positioning portion, and the second end of the permanent magnet has a second joint portion; and ajoint member sleeved on the rotating shaft via a through hole, wherein the joint member has a third joint portion, and the third joint portion is combined with the second joint portion of the permanent magnet.

Description

technical field [0001] The present invention relates to a rotor, especially a rotor of an inner rotor motor, the rotating shaft of which is combined with permanent magnets. Background technique [0002] The existing motor rotor structure has a rotating shaft and a permanent magnet. The permanent magnet is in the shape of a cylinder and has a shaft hole in the center. The permanent magnet can be sleeved on the rotating shaft so that the permanent magnet is combined with the rotating shaft. and rotate synchronously. [0003] Wherein, the combination method between the rotating shaft and the permanent magnet is to apply an adhesive between the rotating shaft and the shaft hole of the permanent magnet, so that the permanent magnet can be adhered to the rotating shaft and rotate synchronously . However, the adhesive itself has a certain lifespan, and the rotor structure is in a high-temperature, high-speed rotating environment for a long time, so the adhesive is easy to deterio...
