Resolver characteristic evaluation device "RI-1000"
Output errors in a state of stator and rotor eccentricity can be measured with high resolution of 0.01°.
The "RI-1000" is a device for evaluating the characteristics of resolvers, capable of measuring electrical characteristics such as impedance under eccentric conditions. Eccentricity corresponds to horizontal eccentricity relative to the stator and rotor, axial tilt, and thrust direction offset. Additionally, it can measure output angle error with a high resolution of 0.01° under conditions of stator and rotor eccentricity. 【Features】 ■ Capable of measuring output angle error with a high resolution of 0.01° ■ Can simultaneously conduct electrical characteristic tests and eccentricity characteristic tests ■ Capable of measuring angle error at speeds up to 12,000 rpm ■ Suitable for next-generation resolver evaluation *For more details, please refer to the PDF document or feel free to contact us.
