It manufactures, D and M and the flange mounting hole of tested motor are manufactured, and D size should be slightly bigger than the flange face maximum gauge of tested motor, are turned
Changing set internal via shape can also be extended to other shapes, such as triangle, pentagon, hexagon, other different forms.
When 300 shape of tested motor stator is non-bowlder, realized using conversion sleeve 400 and gland 500.Conversion sleeve 400
Hole size and shape and the shape and shape of the stator 300 of tested motor mutually manufacture, the height H size of conversion sleeve 400 is answered
0.2-0.3mm smaller than the stator 300 iron core height of tested motor, the hole size D1 of gland 500 should be than tested motor stator 300
The line end outer diameter big 2-3mm of D, the outer diameter of conversion sleeve 400 can arrange lower screw hole；Tested motor when work
Stator 300 be inserted in 400 inner hole of conversion sleeve, both ends with gland 500 compress, the stator 300 of such tested motor just with conversion
Set 400 is integrally formed；400 internal via shape of conversion sleeve can also be extended to other shapes.As triangle, pentagon, hexagon,
Other different forms etc..
Since two side plates 67, holder 51 are connected together by dovetail slide block 55 and dovetail guide 670, two side plates 67 are also
It connects together with guide rail mounting plate 61, when moving side plate 67 in this way, the clamp structure 50 and height adjusting structure 60 on the right
It can move integrally, since the installation bolt through-hole of side plate 67 uses kidney-shaped oblong aperture, the centers of two circles are away from being 30mm, bottom plate 10
On also have row's centre bore away from the threaded hole for 30mm, such side plate 67 can be moved axially along positioning strip 12 or so, this
Sample can as needed test the test block of random length.
