　　MT4000-Permanent Magnet Synchronous 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

　　Using asynchronous motor/permanent magnet motor as the test motor load, changing the traditional load mode, improving the system's dynamic measurement range and accuracy of torque and speed, improving the loading performance (forward/reverse, reverse drag), and shortening the load response Time, can realize the loading of any load curve, highly simulating the real-time operating conditions of the motor/drive.

　　05Humanized design

　　Using a professional motor test bench, the fixture has a quick centering function, and is convenient for loading and unloading and adjustment of coaxiality, which 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 tests in a single position Operational layout.
