Description

technical field [0001] The invention relates to the technical field of angle measurement, in particular to a resolver inspection device and an inspection method thereof. Background technique [0002] At present, the most widely used angle measurement devices are photoelectric encoders and resolvers. However, photoelectric encoders should not be used in harsh conditions. In contrast, the resolver has a stator, rotor and winding inside, with a simple structure, no integrated electronic components, high reliability, good performance in anti-vibration and high and low temperature, not easily affected by the environment, and can be applied in various conditions Harsh occasions, such as widely used in the automotive field, aerospace field. [0003] Resolvers need to carry out type inspection and factory inspection respectively in the process of trial design and mass production. Type inspection is an inspection to verify whether the sampled product can meet all the requirements ...
