The base plate 1 provides positioning support for the machine base 5, enabling the positioning fixture to position and support both the stator and the machine base, facilitating subsequent installation work, simplifying the positioning and installation device, and improving overall installation efficiency.

[0045] The bending part of the protective pad 31 away from the inner cylinder 3 is provided with a rounded corner structure.

[0046] Further, the number of protective pads 31 is multiple, and each protective pad 31 is uniformly distributed on the upper end of the inner cylinder 3. In this embodiment, four protective pads 31 are provided and symmetrically distributed on the upper end of the inner cylinder, which can effectively protect the stator inner hole.
