Problems solved by technology

[0003] However, if the rotor 93 of the above-mentioned conventional internal rotor motor 9 has problems such as asymmetrical shape, manufacturing tolerance, deformation, or uneven material distribution, the rotor 93 is prone to problems such as rotational imbalance during rotation, which in turn will cause problems such as vibration , noise or motor function damage and other adverse effects
Therefore, after the rotor 93 is manufactured, the assembler must calibrate and test the balance state of the rotor 93 until the rotor 93 can reach rotational balance. Waste of assembly efficiency and poor calibration accuracy, so it is necessary to improve

Abstract

An inner-rotor motor is used for solving the non-balance of the former inner-rotor rotating and the difficulty of adjustment or test. The inner-rotor comprises a shell, a stator and a rotor. The shell has at least one pivot part. The stator disposes on the inside of the shell. The rotor has a shaft and a permanent magnet. The shaft rotatably combines with the pivot part of the shell. The permanent magnet combines with the shaft. An air gap forms between the permanent magnet and the stator. A plurality of balance pieces disposes at least one end of the permanent magnet.

Description

technical field [0001] The invention relates to an inner rotor motor, especially an inner rotor motor which can ensure the smooth rotation of the rotor. Background technique [0002] Please refer to figure 1 As shown, an existing inner rotor motor 9 is disclosed. The inner rotor motor 9 has a housing 91, and the housing 91 is internally provided with a stator 92 and a rotor 93. A rotating shaft 931 of 91, the outer peripheral surface of the rotating shaft 931 is provided with a permanent magnet 932, there is an air gap between the permanent magnet 932 and the stator 92, the stator 92 can drive the rotor 93 to rotate through the air gap. The detailed structural composition and action principle similar to the above-mentioned existing inner rotor motor 9 are disclosed in China Taiwan No. I371154 "inner rotor motor" invention patent. [0003] However, if the rotor 93 of the above-mentioned conventional internal rotor motor 9 has problems such as asymmetrical shape, manufacturi...
