Zusammenfassung: | The invention provides an electromagnetic bearing test device for a main helium fan, and belongs to the technical field of electromagnetic bearing test devices for main helium fans. In the invention,a cantilever of a loader counterweight plate is installed at the extension end of a drive motor shaft of the main helium fan, the loader counterweight plate and the shaft adopt a cone interference fit, an electromagnetic force device is installed under the loader counterweight plate, a speed sensor is arranged on one side of the loader counterweight plate, the loader counterweight plate is matchedwith a loader bracket through the motor shaft and equipped with a counterweight plate end cover to realize axial orientation of the loader counterweight plate and the motor shaft, and the loader bracket is equipped with a force sensor. The electromagnetic bearing test device for the main helium fan solves the problem that the air gap between a loading plate and a loading part will change during the loading test, and can e |
