Document Type and Number:
WIPO Patent Application WO/2022/095608
Kind Code:
A1
Abstract:
Provided by the present utility model is a stator module, comprising a winding core; also comprising a housing provided with two through-holes and an isolation sleeve having an outer diameter identical to the diameter of the through-holes; the two through-holes are coaxial; the side of the isolation sleeve is fixed to the inner wall of the through-hole, and the circumferential outer wall of the isolation sleeve and the inner wall of the housing are enclosed as a sealed chamber; the winding core is fixed in the sealed chamber, and the winding core is located in the circumferential direction of the isolation sleeve. In the stator module of the present utility model, the winding core is assembled with the sealed chamber formed by the housing, and the isolation sleeve is isolated from the external environment; no adhesive-filling and packaging is required, preventing local overheating of the winding core, and the assembly process is simple and time-consuming curing is unnecessary; the inner wall of the isolation sleeve serves as the mounting space for a rotor, the stator module may be sold as a single component product, and the rotor can mounted on the inner wall of the isolation sleeve by means of a corresponding matching bearing so as to be assembled into a simple electric motor, having a broad range of applications; thus the electric motor and pipeline pump are further extended by the stator module.
