Thrust detection of linear motors

¡¡¡¡A linear motor is a transmission that converts electrical energy directly into linear motion mechanical energy without the need for any intermediate switching mechanism. The amount of linear motor output is mainly thrust, due to the theory of the linear motor, design, manufacture and load and interference and many other reasons, will cause the linear motor thrust fluctuations, so we must test the linear motor.
¡¡¡¡The thrust detection of the linear motor can reflect the smooth running of the linear motor. Therefore, the thrust detection is the key parameter of the linear motor detection. The following describes the thrust fluctuation test of the straight motor.
¡¡¡¡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 connects the linear motor through the ball screw, so that the interference of the mechanical connection mechanism is inevitably entered into the detection result of the fluctuation, which leads to the test result and the expected deviation.
¡¡¡¡We use the new¡¡wave of test solutions, the same rail with two models of the same type of linear motor load each other, through the appropriate conditions of the thrust signal collected by the data processing, and ultimately get the linear motor thrust characteristics The
¡¡¡¡We use 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 performance, which avoids the torque ripple introduced during the rotation of the rotating motor and is simple Of the connection device to replace the ball screw, to a large extent to solve the mechanical connection part of the uncertainty and disturbance, improve 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.
¡¡¡¡Kunshan Tongmao ten years to focus on linear motor, voice coil motor R & D and production, to provide customers with a complete set of solutions, including multi-axis control system, precision transmission parts and installation and commissioning. We factory for each of the straight line motor test run to ensure that the factory of each linear motor is good. Linear motor all the production processes are completed in the factory, each process has a rigorous testing, 100% to ensure product stability.
¡¡¡¡Welcome friends a lot of attention with Tongmao straight
