　　MT4000—DC Motor Test System—Main Features

　　01 Functional modularity

　　All the benches are built using functional modularity, and are combined into one test system in the form of a combination of modules. Customers can add or remove test modules according to different test objects.

　　02 Advanced measurement methods

　　Adopting 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 characteristic value data, which is convenient for the software to test Comprehensive analysis of process data.

　　03 Complete test items

　　According to the test requirements specified in the national standard, test items can be added or removed 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 motor under test, which changes the traditional way of using a dynamometer as the load, improves the dynamic measurement range and accuracy of the torque and speed of the system, improves the loading performance (forward/reverse, reverse drag), and shortens the load The response time can realize the loading of any load curve and highly simulate the real-time operating conditions of the motor/drive.

　　05Humanized design

　　The professional motor test bench is adopted. The fixture has three-dimensional adjustment function, and it is convenient to install and unload and adjust the coaxiality. It can be adapted to the installation of the tested motor of any shape. The system operation adopts the piano table control mode, which can complete all test operations in a single position. layout.

　　06 Customized testing software

　　The motor test system test software developed by the Sichuan Chengbang Software R&D team, according to the national standard requirements test items, classifies the software interface and process, reduces repeated tests, and greatly improves the work efficiency of testers. And it has the functions of real-time curve drawing, transient value capture, trend curve drawing and analysis, multi-parameter combination display, qualified judgment, report export and so on.
