Size is smaller, can be mounted in the 3rd room 15.
It refer to shown in Fig. 6 and Fig. 7, the step 1 of the stator module can only have first room 12.Such as Fig. 6 institutes
Show, the maximum radial width W2 of first room 12 can be more than the maximum radial width W3 of the joint passage 21, and first appearance
Room 12 is fully located at outside the joint passage 21；Or as shown in fig. 7, it may also set up the maximum radial width of first room 12
W2 is less than the maximum radial width W3 of the joint passage 21, so that the part of the first room 12 is located in the joint passage 21.
By said structure, second end 212 is formed because the supporting part 34 of the top chock 3 is connected to the iron core 2
Side, therefore can firmly carry the second bearing 5 and ensure that the second bearing 5 will not produce movement relative to the iron core 2.This
Outside, because the step 1 and the top chock 3 separation are set, therefore it can regard demand adjustment during motor assembling and be somebody's turn to do
Rotor passes through the opportunity of the joint passage 21 of the iron core 2, to avoid the top chock 3 and the second bearing 5 from departing from default location
And influence the structural soundness of the stator module.
Fig. 8 is refer to, is the second embodiment of external-rotor motor stator module of the present invention.Compared to aforementioned first embodiment
External-rotor motor stator module, the first openend 13 of the step 1 of the present embodiment is formed radially one along the central siphon 11
131 and one outer top surface 132 of inner top surface, and the inner top surface 131 and the outer top surface 132 have height in the axial direction of the central siphon 11
Difference；In addition, the second openend 33 of the top chock 3 is also formed radially an inner ring surface 331 and an outer ring surface 332 along this, and should
Inner ring surface 331 and the outer ring surface 332 also have difference in height on the axial direction.Above-mentioned inner ring surface 331 towards the inner top surface 131,
The outer ring surface 332 is towards the outer top surface 132；Meanwhile the difference in height between the inner top surface 131 and the outer top surface 132, preferably at this
Radially the difference in height between the inner ring surface 331 and the outer ring surface 332 overlaps.In detail, on the axial direction, the outer ring surface
332 can be protruded from outside the inner ring surface 331, and the inner top surface 131 is protruded from outside the outer top surface 132, and being located at the inner top surface 131 should
