This invention discloses a permanent synchronous generator rotor location sensing method and location sensing device, which uses rotary transformer and solving cell as sensor, and it has digit signal dealing cell, where the solving cells samples detection generator location angle in real time and fixing time interval, and it judges the change of the generator location angle after each sampling to determine whether to complement and correction. If the solving cell checks out that the extent of the rotary transformer's sensing signal of the output exceeds the allowing range, then it sends the demand to control the permanent synchronous generator to stop running to the digit signal dealing cell. This invention also discloses a permanent synchronous rotor location sensing device, which is compatible with bad magnetic environment of motor car or mixed motor car, and it can keep the generator running stably under the environment that the rotary transformer or solving cell has big error or invalidate. So this invention can be applied extensively in electric servo system of middle or small power including electric automobile and mixing motor car' driving part. |
