Abstract

The invention discloses a function test system for an angle detection circuit of a rotary transformer. A test device and a decoding integrated chip of the angle detection circuit of the rotary transformer to be tested are in communication through a microprocessor, and configuration and information capture of the decoding integrated chip in the test process are achieved. The function test system is used for detecting whether angle analysis of the decoding integrated chip of the angle detection circuit of the rotary transformer to be tested is accurate, whether the reset function is normal, whether a return input module of the angle detection circuit of the rotary transformer to be tested has faults and whether an excitation output module of the angle detection circuit of the rotary transformer to be tested has faults. The function test system for the angle detection circuit of the rotary transformer is low in test cost and short in test time.

Description

technical field [0001] The invention relates to automatic test technology, in particular to a function test system for a rotary transformer angle detection circuit. Background technique [0002] A resolver (resolver / transformer) is an electromagnetic sensor, also known as a synchronous resolver. It is a small AC motor for measuring angles, used to measure the angular displacement and angular velocity of the rotating object, and consists of a stator and a rotor. Among them, the stator winding is used as the primary side of the transformer to receive the excitation voltage, and the rotor winding is used as the secondary side of the transformer to obtain the induced voltage through electromagnetic coupling. [0003] The working principle of the resolver is basically similar to that of the ordinary transformer, the difference is that the primary and secondary windings of the ordinary transformer are relatively fixed, so the ratio of the output voltage to the input voltage is co...
