Power supply - used to power the system and the motor under test.
For the user, the dynamometer solves the most troublesome problems - loading and data collection, but the processing of the test results still needs to be done manually.
In fact, based on the dynamometer motor test, the speed is still very slow, so there is a next-generation product - the motor test system.
Self-cultivation of a motor test system
An ideal motor test system, when performing each test project, the tester only needs to pay attention to the input quantity (set the test environment parameters), and the output (test result and report) can be obtained. So the dynamometer made a gorgeous upgrade, and through the introduction of PLC and industrial computer, the automation of control, loading and measurement was realized:
At this point, the basic framework of the motor test system has matured. This type of motor testing system is the most popular in the current application, but due to the user's usage habits, many names continue to be called "dynamometers". Such systems have been able to meet the needs of routine test projects for most common motors.
Industrialization and professional future
The basic framework of the current motor test system has matured, so where is the next direction of development? Let's go back and analyze the test object of the motor. The family of motors is very large. As mentioned earlier in the article, different types of motors have different characteristics, and the performance points that need attention are not the same. Like servo motors pay attention to the linearity and control speed of their control, home appliances and motors pay attention to their efficiency, electric motor motors pay attention to their power density and high efficiency zone... In the future, motor test systems should also be supplemented by test functions in different motor industry applications. perfect.
It is well known that a motor is a fusion of electrical and mechanical crystallization. To evaluate the performance of a motor, it is often necessary to combine the results of many test projects to evaluate. Generally, a motor needs to undergo two stages of type test (development, pilot test, quality inspection) and production test (factory) from research and development to production. According to the type of motor and the application industry, there are more than ten kinds of products. Even dozens of pilot projects.
Since there are so many test items for the motor, it also requires a lot of test instruments or equipment to complete the test of each project. For the collection of voltage, current and power, the electric parameter tester is needed; the speed and torque are collected by the corresponding sensors; in order to let the motor run under different working conditions, the mechanical load must be added; after the test is completed It also needs to manually process the data and draw the curve... All this is quite complicated and troublesome for the testers. Is there a once-and-for-all test solution?
