| Abstract: | Stability and reliability of the control system of magnetic bearings are the key to guarantee bearings to work normally and not to be destroyed accidentally, so test and diagnosis of control circuits are very important. Test and diagnosis technology are researched about combinational logic circuits of the control system of magnetic bearings to be used in hard disk drives. Test and diagnosis ways are presented for some common categories of faults including chip level faults, stuck at faults and misconnection faults etc. |
