VGX Series Robot Joint Motor Test System

The VGX series adopts a high-precision dynamic dynamometer platform, compatible with various models such as robot joint servo motors and frameless torque motors. It covers a test torque range of 0.1–50 Nm, a power range of 100 W–15 kW, and a maximum speed of up to 15,000 rpm. The system delivers torque measurement accuracy better than ±0.1% FS and speed accuracy of ±0.1 rpm, with high dynamic response characteristics to truly simulate complex working conditions including start-stop, direction reversal and variable load of robots. Equipped with four-quadrant energy feedback technology, it achieves an energy recovery rate of ≥90%, enabling energy-efficient and long-term aging and durability tests. It supports synchronous acquisition of multiple parameters including torque, speed, efficiency, temperature rise, step response, torque ripple and encoder signals, with a sampling frequency of over 1 kHz. The system features comprehensive safety protection for overcurrent, overvoltage, overload, overspeed and over-temperature. With a modular structure and standardized communication interfaces compatible with mainstream industrial fieldbuses, it automatically stores, analyzes test data and generates professional reports, fully meeting high-precision testing requirements for R&D calibration, production line inspection and reliability verification.
