The amount of linear motor output is mainly thrust, due to the linear motor theory, design, manufacture and load and interference and many other reasons, will cause the linear motor thrust fluctuations, it must be on the linear motor detection. The thrust detection of the linear motor can reflect whether the linear motor is running smoothly. Therefore, the thrust detection is the key parameter of the linear motor detection.
What is the linear motor thrust detection? How to operate?
Common thrust fluctuation test system is used by the ball screw and linear motor were dragged drag plate, coaxial on the drag to test the thrust fluctuations. This kind of rotating electric machine through the ball screw to connect the linear motor method, so that the mechanical connection mechanism of the interference is also inevitably entered the detection of fluctuations in the results, resulting in test results are often expected with the considerable deviation.
The new wave test solution is the same rail on the same type of linear motor with each other load, through the appropriate conditions of the thrust signal collected by the data processing, and ultimately get the linear motor thrust characteristics.
Using two linear motors that are loaded with each other, including the linear motor and the test linear motor, which have the same electrical and mechanical properties, which avoids the torque ripple introduced during the rotation of the rotating motor and is connected with a simple connection Device replacement ball screw, to a large extent to solve the mechanical connection part of the uncertainty and disturbance, to enhance the transmission efficiency. Through the use of appropriate control detection method, so that the two motor after the superposition of the fluctuations in the same phase, and then get the measured motor thrust fluctuations.
