Embodiment

[0032] A teaching experiment system for advanced drive control algorithms of AC motors, such as figure 1 As shown, including power conversion module, central control module, power drive module, control parameter setting module, control algorithm selection module, parameter measurement and display module, motor loading module, host computer module, serial port, data acquisition card, Hall sensor , photoelectric encoder and motor.

[0033] The functions of the above-mentioned components and the connection relationship among them are as follows:

[0034] Among them, the power conversion module is responsible for providing power to other modules, displaying the corresponding voltage and current values ​​and having an over-current protection function. When the current is higher than 5A, it will automatically cut off the power. Specifically, in this embodiment, AC-DC isolated power supplies NET-50C and S-350-48 of MEAN WELL can be used.

[0035]The central control module is used t...
