DJCS4000-three-phase asynchronous motor test system-main features

  01 Functional Modular
  Function modularization is adopted for all the platform construction, and the combination of modules is concentrated in a test system. Customers can add or subtract test modules according to the different test objects.
  02 Advanced measurement methods
Adopt advanced real-time measurement and control system, including input electrical parameter test, speed and torque test, etc. The torque and speed sampling rate is up to 1000Hz, which meets the high precision and fast response requirements of the test system, and provides transient data and eigenvalue data to facilitate the later test of the software Comprehensive analysis of process data.
  03 Complete test items
  According to the test requirements of the national standard, the test items can be increased or decreased according to the configuration module, which can meet the test items for various types of tests
  04 Motor load
The servo motor is used as the load of the tested motor, which changes the traditional way of using the dynamometer as the load, improves the dynamic measurement range and accuracy of the system's torque and speed, improves the loading performance (forward/reverse, reverse drag), and shortens the loading The response time can realize the loading of any load curve and highly simulate the real-time operating conditions of the motor/driver.
  05 Humanized design
A professional motor test bench is used. The fixture has three-dimensional adjustment function, and it is convenient for loading and unloading and coaxiality adjustment. It can adapt to the installation of the tested motor of any shape. The system operation adopts the piano desktop control mode, which can complete all test operations in a single position. layout.
  06 Customized test software
  The motor test system test software developed by Sichuan Chengbang Software R&D team classifies the software interface and process according to the test items required by the national standard to reduce repetitive tests and greatly improve the work efficiency of test personnel. And with real-time curve drawing, transient value capture, trend curve drawing and analysis, multi-parameter combination display, qualified judgment, report export and other functions.
