Abstract

The invention discloses an alternating current servo loading test system, which comprises a servo twin trawling platform, a loading alternating current servo, a tested alternating current servo and aloading control platform, the servo twin trawling platform is used for fixing a tested alternating current servo and the loading alternating current servo; the tested alternating current servo is coaxially connected with the loading alternating current servo; the loading alternating current servo is connected to the power supply input end of the tested alternating current servo by leading out a direct current bus of the loading alternating current servo; and the loading control platform is used for controlling the tested alternating current servo and the loading alternating current servo. According to the invention, an energy feedback unit commonly used in the prior art is removed.The direct current bus loaded with the alternating current servo is led out and directly connected to the input end of the alternating current power supply of the tested alternating current servo, so that harmonic pollution caused by connection with an external network through the energy feedback unit is successfully avoided, the energy loss is reduced, and the installation cost of the test system is effectively reduced while the energy feedback efficiency is improved.

Description

technical field [0001] The invention relates to the field of servo testing, in particular to an AC servo loading testing system. Background technique [0002] The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator, and has the characteristics of small electromechanical time constant, high linearity, and small starting current. The signal is converted into an angular displacement or an angular velocity output on the motor shaft, which makes it increasingly occupy an important place in the development of high-precision technology. [0003] In the field of industrial automation, AC servo motor drive applications are also very common. In the research and development stage, the AC servo driver needs to carry out the loadi...
