Description

technical field [0001] The invention relates to the technical field of hollow cup motor automatic manufacturing equipment, in particular to a hollow cup motor rotor polishing device. Background technique [0002] The coreless motor belongs to the DC permanent magnet, servo micro motor. The main difference from the ordinary motor is the ironless rotor, also called the coreless rotor. The stator is magnet steel inside. figure 1 The structure of the coreless motor in the prior art shown includes: a rear cover 1, a brush holder 2, a coreless rotor 3, a gasket 4, a NdFeB magnet 5, a stator 6, a bearing 7, and a retaining spring 8 . Coreless motors have very prominent energy-saving, control and drag characteristics, mainly including: 1. Energy-saving characteristics: energy conversion efficiency is very high, and its maximum efficiency is generally above 70%, and some products can reach above 90% (iron-core motors generally at 20-50%). 2. Control characteristics: fast starting...
