From the project
12 phase motor drive including inverter, microcontroller-mother-board, sensing, communication, DAC, etc.
ProjectEureka seeks to streamline the intricate design of robot systems, including communication, cable arrangements, and synchronization, by integrating several motor drivers (up to four) with a single microcontroller (DSP2837xD). This can also be utilized as a testing platform for bearingless motor or any other kind of AC motors. For access to example codes, please visit the following link: here for cpu01 code, and here for cpu02 code. Displayed below is an image representing the previous version.
