Description

technical field [0001] The invention relates to a linear motor test device, in particular to a linear motor power performance test device for a numerically controlled direct feed axis. Background technique [0002] At present, high-speed processing technology in the world has become one of the main technologies that have developed rapidly in recent years. Linear motors began to appear in machining centers as high-speed feed systems. Since the direct drive feed system has advantages and potentials that cannot be compared with the traditional feed system, it has once again attracted the attention of various countries. As an electromechanical system, the linear motor simplifies the mechanical structure and complicates the electrical control, which is in line with the development trend of modern electromechanical technology. Domestic research on linear motors, especially the research on linear servo motors in machine tool feed systems is still in its infancy, and there is a bi...

Domestic research on linear motors, especially the research on linear servo motors in machine tool feed systems is still in its infancy, and there is a big gap with foreign countries

On the other hand, there is no complete inspection method and testing equipment for linear motors in China. Basically, some specific parameters are tested with existing equipment according to the type and occasion of the motor used. Moreover, it basically draws on the corresponding methods of rotating electrical machines and the formulation of relevant national standards.

These test methods cannot test some specific characteristics of linear motors, and the test results cannot fully and accurately reflect the working performance of linear motors. The development of experimental methods and experimental equipment for the performance of linear motors is very important.
