Eddy current sensors are widely used in the measurement of rotor bearings and flywheels in industrial production. With the increase of the speed and the reduction of the volume of the high-speed rotating body, the accuracy of the sensor will be improved, so that the test accuracy and structural design of the eddy current sensor test equipment have higher requirements.

    The motor rotor position (eddy current) sensor test equipment launched by Pan China Measurement and Control has solved the user's pain points and difficulties in many aspects from design to manufacturing, and a number of technical indicators are advanced in the industry. According to the different needs of R&D/production users, Panhua provides different appearance design and customized index parameters for the equipment in the laboratory and production line two scenarios, and supports the tooling change and compatible with a variety of eddy current sensors, such as: transmission gear, seat position, steering wheel torque, motor Angle position sensor, etc. Laboratory equipment supports motor speed up to 24000RPM, equipped with high-precision encoder and Panhua's own algorithm, resolution up to 0.02°; Integrated motor spindle design greatly reduces vibration and prolongs motor service life. When used in production line production, the production beat is <60s, and can be automatically programmed.

    Motor rotor position (eddy current) sensor test equipment in the performance test, according to the collected voltage signal, The result values of various parameters of the sensor signal (diffsin offset, diffsin pk2pk, diffcos offset, diffcos pk2pk, electrical Angle error, mechanical error, average electrical Angle error, average mechanical error, phase) are calculated, and the Angle signal of the motor is collected synchronically and saved. At the same time, it also has the function of repeated test and step test. The software system has the functions of system self-test, manual mode, automatic mode, tooling calibration, programming burning, system monitoring, data management, system configuration, etc., which can meet the development/production testing needs of most eddy current position sensor users in the market.

    Motor rotor position (eddy current) sensor test equipment is composed of two parts: test cabinet and sensor table. The split type design is suitable for the connection of different sensor workbenches and test cabinets, saving equipment space and improving test efficiency. At present, PanChina has reached cooperation with a number of automotive electronic parts head manufacturers and vehicle manufacturers on this equipment.
