[0022] Example
[0023] The rotor of a four-pole permanent magnet synchronous motor of the present invention, such as figure 1 , 2 As shown, it includes a rotating shaft 11, a key 10, a core 9, a magnetic steel 2, a non-magnetic material insulating baffle 1, a collar 6, a copper sheet 8, a slot wedge 5 and a hoop 7;
[0024] Such as Figure 5 As shown, the middle section of the rotating shaft 11 is machined with an annular groove, and four axially slotted and circumferentially distributed key grooves are machined on the annular groove. The side walls of the rotating shaft 11 at both ends of the annular groove are machined with two rows of eight circumferentially evenly distributed offset threaded holes. ;
[0025] Such as image 3 , 4 As shown, the center of the iron core 9 is a circular cylinder with an inner diameter and a length matching the annular groove of the rotating shaft 11 and cut into four segments with the same structure and a sector-shaped section. The outer wall of eac...
