AI Technical Summary

Problems solved by technology

Once the parameters of the control system are not well designed, instability will easily occur during on-site debugging, which may not only damage the extremely expensive mechanical equipment, but also cause great psychological pressure and panic to the on-site debugging technicians
Magnetic suspension bearings have gradually been widely used in industrial occasions at home and abroad, but there is no system for on-site debugging of magnetic suspension bearings.

Description

1. Technical field [0001] The invention relates to a magnetic suspension bearing debugging system, in particular to a magnetic suspension bearing simulation field debugging system. 2. Background technology [0002] Magnetic suspension bearings are generally used in high-speed or ultra-high-speed occasions that cannot be met by mechanical bearings in industry. The performance of the control system directly determines the performance of magnetic suspension bearings. Once the parameters of the control system are not well designed, instability will easily occur during on-site debugging, which may not only damage the extremely expensive mechanical equipment, but also cause great psychological pressure and panic to the on-site debugging technicians. Magnetic suspension bearings have been gradually and widely used in industrial occasions at home and abroad, but there is no system for on-site debugging of magnetic suspension bearings. 3. Contents of the invention [0003] 1. Purp...
