Test System of Drive Motor and Controller for MTS-IV-18488 Vehicle
Composition--
electric dynamometer
frequency conversion control system
Drive motor and controller test system
DC regulated power supply
Measured parameters--
Driver input voltage, current, power
Driver output voltage, current, power, power factor, frequency
Motor output torque, speed, power
Drive efficiency, motor efficiency, total motor efficiency
Function--
All data and charts are displayed on the computer, and all operations can be completed on the computer.
The system has the automatic test function of MAP chart: the test can be completed by one key of the software, and the test curve, report, efficiency MAP chart and efficiency interval distribution chart can be automatically generated;
The system has a manual test mode: the load is adjusted manually, and the data is recorded or collected manually;
The system has an automatic test mode: that is, the load is automatically loaded according to the setting, scans the characteristic curve of the motor from no-load to blocked rotation (or set value), and automatically calculates the efficiency platform and feature points;
