What is the shaft of the motor?

The rotating shaft of the motor is the core part of the rotor part, which carries and supports the rotor core, and cooperates with the bearing and the end cover to control the axial position size of the rotor. The motor shaft is composed of the following five parts:-front shaft extension end-front bearing gear-iron core gear-rear bearing gear-fan gear. Strictly speaking, between the left and right sides of the iron core gear and the bearing gear, there is a part with an outer diameter slightly smaller than the iron core gear but larger than the bearing gear near the front bearing, which is used to guide the rotor iron core during press fitting; The outer diameter is slightly larger than the iron core gear at the rear bearing, of course, it is larger than the bearing gear and is used for axial positioning of the rotor core during press fitting.
