Comprehensive test device for linear motor motion system

Abstract

The invention discloses a comprehensive test device for a linear motor motion system, which belongs to the field of motor test equipment. The comprehensive test device consists of a tested linear motor, a rotating servo motor, a torque motor, a sensor module and a transmission mechanism. Linear motion guide rails and a linear position sensor are fixed on a workbench; a linear motor primary section is arranged on the linear motion guide rails; the output of a controller is connected with each sensor through one communication interface; the sensors transmit position, acceleration, tensile forceand temperature measurement signals obtained in a test process through the communication interfaces; and the rotating servo motor, the torque motor and the linear motor realize coordinated motion with the controller through communication interfaces. The test device can finish the plurality of tests of dynamic stiffness tests, thrust coefficient determination, temperature rise tests, low-speed motion characteristic tests and the like on a linear motor-driven machine tool feeding system, and solve the problems of absence of a complete set of test device, low test accuracy and low repeatability of the linear motor-driven machine tool feeding system.

Description

technical field [0001] The invention belongs to the field of motor testing equipment, and in particular relates to a linear motor motion system comprehensive test device for realizing the stability test, thrust coefficient measurement, temperature rise test and low-speed motion characteristic test of the linear motor motion system.

Problems solved by technology

The weak point of this device is: the position of the primary 101 of the linear motor relative to the secondary 102 of the linear motor is calculated according to the pulse sent by the computer 131, and the calculation process will introduce deviation; The speed fluctuation will affect the measurement accuracy

[0004] The test device has the following problems: (1) The synchronous belt is used as the transmission medium, but it is not suitable for positioning and dynamic force tests due to its excessive deflection and creep and response delay; (2) It can only be used to complete One test (servo stiffness); (2) Interference factors cannot be effectively eliminated in the test device, the measurement accuracy is difficult to guarantee, and the repeatability is poor

[0005] There is no comprehensive test device for the multi-parameters and performance of the linear motor motion system (such as friction, viscosity coefficient and other parameters and system stability test)
