AT4000—Starter Motor Test System

Case Presentation

  AT4000—Starter Motor Test System—Product Background

  Overview:

  Starter motors are widely used in the automotive field. Product performance and product quality must be ensured during product development and factory inspection. Therefore, it is particularly important to conduct strict tests on the performance of the starter motor. According to the national standard GB/T 26674-2011 "Test Method for the Electrical Characteristics of Road Vehicle Starters" and with reference to other national standards and various motor test standards, the system conducts type verification tests on the motor test purpose, test procedures and test methods.

  AT4000—Starter 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

  Using asynchronous motor/servo motor as the load of the tested electric drive assembly, changing the traditional load method, improving the dynamic measurement range and accuracy of the torque and speed of the system, improving the loading performance (forward/reverse, reverse drag), and shortening the load The response time can realize the loading of any load curve and highly simulate the real-time operating conditions of the electric drive assembly.

  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. It can be adapted to the installation of the tested motor of any shape. The system operation adopts the piano table / cabinet + computer desk control mode, which can be completed Complete the layout of all test operations in a single location.

  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.
