he power part of the traditional elevator is mainly composed of traction machine, frequency converter, car, wire rope and pair. By rolling the wire rope, the traction machine adjusts the balance between the cage and the weight to control the height of the cage, that is, up and down the elevator. The product research and development and factory inspection of traction machine must ensure the product performance and product quality, so it is particularly important to carry out strict test and analysis on the performance of traction machine. According to the national standard GB/T 24478-2009 "Elevator Tractor" and referring to the requirements of other national standards and various elevator tractor test standards, this system carries out type verification test on the tractor test purpose, test procedure and test method.

NT4000 -- Tractor test system adopts modular and integrated design, the operation part conforms to ergonomic design, and can complete manual/automatic mode control. The bench is divided into single tractor test bench and double tractor towing test bench, which is mainly composed of mechanical system, electrical system and upper computer software system.
Mechanical system: mechanical platform, loading equipment (electric dynamometer/traction machine), clamping system, shafting connection part and other equipment.
L Electrical system: drive controller, load control, real-time data acquisition system for sensors (torque, speed, current, voltage, vibration, temperature), data acquisition, current sensor acquisition, electrical parameter measurement equipment, alarm system and other equipment.
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. By the upper computer according to the test project to complete the test control, data analysis and display, data record and export and other functions.

Experimental items:
Test parameters: input current, voltage, power factor, electric power, output torque, speed, power, efficiency, temperature rise, vibration noise, etc.
The tractor test system is suitable for the whole performance test in the process of positive start → upline → braking → reverse start → downlink → braking when simulating the actual operating conditions of the tractor. This system mainly completes the test torque, speed and other tests. And complete the data collection, storage, report form, curve drawing and printing functions. It is to complete the factory test and development performance test of the tractor.
In the main test process, the tractor is running forward as a motor, while it is running backward as a generator when it is running downward. In order to simulate the actual operating conditions of the traction machine, such as the up-going electric traction machine and the down-going electric traction machine, the load must be able to drive/load (generator/motor, forward-turning/inverting) in four quadrantals. During the whole operation, the speed is between 0 and steady speed, but the test load is required to be constant.
NT4000 - Tractor 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 various type verification test items
04 Motor load
The induction motor/permanent magnet motor/traction machine is adopted as the load of the tested motor to change the traditional load mode, improve the dynamic measurement range and accuracy of the torque and speed of the system, improve the loading performance (positive/reverse, backdrag), and shorten the loading response time.
05 Humanized design
Adopt professional bench design, fixture has quick docking function, and convenient loading and unloading can be adapted to different specimen installation.
Customized test software
The tractor test system test software developed by Sichuan Chengbang software research and development team designs the software according to the test process, categorizes the software interface and control process, reduces the repetition of tests, and greatly improves the work efficiency of test personnel. It also has the functions of real-time curve drawing, transient value capture, trend curve drawing and analysis, multi-parameter combination display, qualification determination, report export and so on.
