Scope

This document specifies the testing requirements and methods for the geometric and electrical parameters of active magnetic suspension bearings stators, describes the measurement steps and data processing methods for the dimensions and tolerances (such as inner diameter, outer diameter, coaxiality, cylindricity, etc.) of radial and axial active magnetic suspension bearings stators, and presents the measurement principles and operating guidelines for electrical parameters (including insulation resistance, inter-turn insulation, winding inductance/resistance, magnetic induction intensity, etc.).
This document is applicable to the testing of active magnetic suspension bearing stators. Hybrid magnetic suspension bearing stators can be referenced for implementation.
This document is not applicable to the testing of the dynamic performance indicators of active magnetic suspension bearing stators.
