Abstract

The invention relates to a motor driving testing device with a microsecond-grade real-time control data monitoring function. The device comprises a data processor, a controller, a driver, double PWM topological units and a control center, wherein the data processor, the controller, the driver and the double PWM topological units are sequentially connected in series, and the controller is further connected with the control center; the data processor and the two PWM topological units are connected with a motor to be tested; the data processor comprises a sampling module and a first operation amplification module; the sampling module is connected with the first operation amplification module; the controller comprises a second operation amplification module, a A\D conversion module, a DSP module; and the second operation amplification module, the A\D conversion module and the DSP module are sequentially connected in series. According to the device, the transmission of the control data of the microsecond-grade speed can be realized, and the control center can collect and monitor the control data in real time at the speed of the microsecond-grade.

Description

technical field [0001] The invention relates to the technical field of motor drive control, in particular to a motor drive test device with microsecond-level real-time control data monitoring. Background technique [0002] The motor controller controls the motor to work according to the set direction, speed, angle and response time through active work. Stator current, voltage, speed and other parameters are the standards to measure whether the motor is running normally or not. Motor drive control mostly adopts DSP to control now, but this can not realize the real-time acquisition of data, the real-time update of control data, existing motor drive test device, as CN108173466A [a kind of motor drive control method and its system], CN106842024A [ A new type of motor control performance test system] simply connects the motor with the driver and controller, and does not upload the data to the server or PC, but the controller cannot store, collect and monitor the data in real tim...
