MOTOR, CRADLE HEAD AND PHOTOGRAPHING DEVICE
FIG7 is a main view of an assembled structure shown in FIG6 
The positioning sensing assembly 115 is attached to the second shaft 1123 and is enclosed in the second housing space 112a of the second body 112. The pressing plate 116 is pressed on top of the position sensing assembly 115. The plurality of mounting posts 1162 penetrate through the corresponding plurality of through-holes 1151c to couple to the corresponding plurality of mounting holes 1125, such that the position sensing assembly 115 is fixed to the second shaft 112. The first position sensor 1152a is separated from an end of the second limiter 1124 adjacent to the first position sensor 1152a by a pre-determined angle a2 (referring to FIG7). In some embodiments, the angle a2 is about 40°. Of course, the angle a2 may increase or decrease according to actual requirements, and will not be described in detail. The coil winding 114 is securely mounted in the second housing space 112a of the second body 112.
