Window Lift Motor Durability Testing System The window lift motor durability testing system is for the durability of a window lift motor. The system contains control system, which can control the system and collect, save, and analyze the test data, and chamber which can control temperature and humidity. Totally, six specimens can be tested at the same time by created cycle profiles.

Fig 1 is the overview of the system and Fig 2 is the driving module which is a torque applying and measuring equipment. Specimens are placed inside the chamber and the driving module is placed outside the chamber for protecting effect. Therefore, there is a spindle Fig. 1 Window lift motor Test system Overview between specimen jig and driving module to transmit power. After the operating signal from the controller, the specimen (window motor) is started, then the torque is applied to the motor spindle by the powder clutch. For applying the impact pneumatic actuator holds the motor rotation. Fig....

Fig 3 is the schematic diagram for the window lift motor test system. The system is controlled by a server PC which can collect, save, and analyze the data. The multi-channel A/D board is software can control and monitor the test process. The controller is mounted at a control rack which contains monitor, PC, keyboard, and mouse. Data from each specimen are voltage, current, torque, angle, and chamber temperature. The test is processed by the user’s control profile. During the durability test, the damage and failure of the specimen is judged by maximum open/close hour, and then stop the test....

Fig. 5 Window lift motor Software (Pre-process) The post process software is to analyze the test operating factor. Each time period can be set by result such as sensor fluctuating value. In addition, maximum or minimum time. Furthermore, each the user can make a report by the purpose and measured data is saved as various file formats such save the report as a PDF file. The saved report with as RPC3 or ASCII. The software has a function that raw data can be loaded by the user and reanalyzed makes and save a graph of the analyzed data from for other purpose. Therefore, the data can be used measured...
