Design and Implementation of Full Automaticity Parameter Tester for Resolver

Introduced a kind of full automatic resolver parameters tester used in the production line in this paper.The instrument used calibration Angle manner,can quickly test form measurement for resolver zero potential point,poles,rotation-angle and calibration-error.The tester was programmed by LabVIEW and the testing functions be accomplished by one key,all of the testing process was accomplished in 5 phases.The best precision of measurement can be achieved by use of calibration manner and max error is less than 0.17578125°by use a decoder whit 10-bit precision.The increase of the pole of resolver will decrease the testing error in multiply.
