Motor simulator and its program

摘要

PROBLEM TO BE SOLVED: To obtain a motor simulator capable of easily verifying a processing unit for correcting the influence of fluctuation characteristics of a power supply voltage included in a control system of a motor control device. A motor simulator includes a simulated power supply unit 20 that outputs a bus voltage based on a DC voltage, and a simulated inverter unit that generates a voltage signal based on a switching signal and a bus voltage output from a motor control device. .. The simulated power supply unit 20 adds the voltage fluctuation component to the DC voltage based on the storage unit 21 that stores the voltage fluctuation information including the information of the voltage fluctuation component different for each power supply environment and the voltage fluctuation information read from the storage unit 21. A bus voltage calculation unit 22 that outputs a voltage signal to which a voltage fluctuation component is added as a bus voltage is provided. [Selection diagram] Fig. 3
