Abstract

The invention relates to a permanent magnet synchronous motor control performance automation test system, which comprises a communication subsystem, a host computer subsystem, a permanent magnet synchronous motor control subsystem, and a direct-current machine control subsystem; wherein a control circuit in the permanent magnet synchronous motor control subsystem is connected with a RS232 switching bridge device in the communication subsystem; a Siemens 6 RA 7025 direct current speed governor in the direct-current machine control subsystem is connected with a communication card CBP2 of the direct current speed governor in the communication subsystem; the communication card CBP2 of the direct current speed governor in the communication subsystem and the RS232 switching bridge device are connected with a programmable controller (PLC) in the host computer subsystem; the communication is realized between the permanent magnet synchronous motor control subsystem and the host computer subsystem by the programming. The permanent magnet synchronous motor control performance automation test system has the advantages of increasing the reliability and capacity of resisting disturbance of the system, realizing the networking control of the whole system, increasing the real time of the system, being capable of simulating any load and saving the energy.

Description

technical field [0001] The invention belongs to the technical field of power electronics and electric transmission, and in particular relates to an automatic test system for the control performance of a permanent magnet synchronous motor. Background technique [0002] In recent years, with the rapid development of my country's industry, the demand for permanent magnet synchronous motors in metallurgy, energy, chemical industry, manufacturing, transportation and other industries has been increasing, so higher and higher performance and quality indicators have been put forward for them. It is of great significance to test the relevant performance (including speed, torque, power, efficiency, etc.) of the permanent magnet synchronous motor and its electric drive control system, and to seek the corresponding test system to complete the test of its mechanical and electrical performance. Therefore, it is imperative to develop a motor automatic test system using advanced industrial ...
