EOL4000 -- EDS drive Assembly on-line performance test system -- Topological structure
EOL4000 -- EDS electric drive assembly online performance testing system USES modular, integrated design, operation part conforms to ergonomic design, can complete manual/automatic mode control. It consists of three parts: mechanical system, system up-down flow control system, guarantee system, electrical system and upper computer software system.
Mechanical system: the whole mechanical platform, loading equipment, shafting connection part and other equipment composition.
L System up-down flow control system: The EDS assembly under test is composed of pre-installed tooling, EDS Assembly, transport roller way /AGV trolley in front of the roller way, positioning and clamping system, automatic completion of shafting, water, electricity, oil and other alignment systems.
L Guarantee system: temperature control system, filling system and other equipment composition.
L Electrical system: bidirectional DC power supply, load control, real-time data acquisition system of sensors (torque, speed, current, voltage, vibration and temperature), data acquisition, current sensor acquisition, electrical parameter measurement equipment, alarm system, NVH vibration, noise and other measuring equipment number scanning system and other equipment composition.
L Software system: Upper computer test software is divided into data acquisition and communication module, data acquisition and setting module, data real-time exchange and control module, and data processing module according to the system. The whole process control procedure is adopted to complete the product qualification evaluation through data acquisition, control and processing. The data link of the entire production system is complete through the connection between the EOL4000 production line workstation system and the production management system, so that the original data of the production inspection system can be traceable.

EOL4000 - EDS drive assembly on-line performance test system - Main features
01 Functional Modularization
The whole design of the platform is adopted, and the modular component combination is adopted inside, which is convenient for the platform combination and maintenance.
02 Advanced means of measurement
Advanced real-time measurement and control system is adopted, including input electrical parameters test, rotational speed torque test, etc. The sampling rate of torque and rotational speed is up to 1000Hz, which meets the requirements of high precision and rapid response of the test system. Moreover, transient data and eigenvalue data are provided to facilitate the comprehensive analysis of test process data by software in the later stage.
The test items are complete
According to the test requirements stipulated by the national standard, the test items can be added or subtracted according to the configuration module, which can meet all kinds of ex-factory test items
04 Motor load
Using asynchronous motor/permanent magnet motor as subjects load, change the traditional way of load and improve the system of dynamic measurement of torque and rotational speed range and precision, improve load (is/reverse, the drag), shorten the response time of load, which can realize arbitrary load curve of load, high simulation of the motor/drive real-time operation condition.
System up and down flow control system.
The EDS assembly is pre-installed through the lifting device to the pre-installed area, and the tested parts are transported to the test bench through the transport roller /AGV trolley mode, and to the test bench through the front roller table, and then the fixture is fixed through the positioning clamping system. The system automatically completes the alignment of shafting, water, electricity, oil, etc., thus completing the docking process of tested parts. After the test is completed, complete the offline process according to the on-line process inversion procedure.
