Abstract

The invention discloses a shafting structure for a motor, and an assembling method. The shafting structure comprises a front-segment shaft (62), a rear-segment shaft (63), annular magnetic steel (61) and an alloy sheath (60), wherein the rear-segment shaft (63) successively comprises a first shaft joint (631) and a second shaft joint (633) from front to back, and the diameter of the first shaft joint (631) is smaller than that of the second shaft joint (633); the annular magnetic steel (61) sleeves the first shaft joint (631) of the rear-segment shaft (63); the external diameter of the rear end of the front-segment shaft (62) is the same as the external diameter of the annular magnetic steel (61); and the alloy sheath (60) sleeves the front-segment shaft (62) and the annular magnetic steel (61). According to the scheme provided by the invention, the shafting structure and the assembling method overcome the defects of complex structure, large assembling difficulty, poor safety and the like in the prior art and also have the advantages of simple structure, small assembling difficulty and good safety.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to a shafting structure and an assembly method for an electric motor, in particular to a shafting structure and an assembly method for an ultra-high-speed electric motor. Background technique [0002] The motor is composed of two parts, the rotor and the stator, and is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor rotor is the rotating part in the motor. [0003] Generally, a rotor whose speed is above 1000 rpm or exceeds the first-order critical speed of the rotor can be regarded as a high-speed rotor. In the patent document with the patent application number "98802132.3", a rotor for a high-speed machine, a manufacturing method thereof, and a motor having the rotor are disclosed. Among them, such as figure 1 , figure 2 As shown, in a high-speed machine rotor and it...
