Over on brushless.zone, we’ve come throughout an fascinating write-up that particulars the development of a dam management system. That is really the second half, within the first, we study that some buddies bought an outdated dysfunctional 80 kW dam with the intention of restoring it. One good friend was answerable for the enterprise paperwork, one good friend the mechanical facet of issues, and the opposite was answerable for the electronics — you possibly can in all probability guess which of them we’re curious about.
The location controller is constructed round a Nucleo-H753 that includes the STM32H753ZI microcontroller, which was chosen on account of it being the most important single-core model of the dev board out there. This web site controller board contains a dozen output mild switches, sixteen front-panel button inputs, twin 24 V PSU inputs, a number of non-isolated analog inputs, atmospheric stress and temperature sensors, a number of analog multiplexers, a pair of SSD1309 OLED screens, and an ESP32 for web connectivity. There’s additionally fiber optic TX and RX for speaking to the valve controller, a trio of remoted hall-effect present sensors for measuring the generator part present, by means of present transformers, 4 contactor outputs (a contactor is a high-current relay), a line voltage ADC, and the cherry on prime — an digital buzzer.
The valve controller has: 48 V enter from both the PSU or battery, motor part output, motor subject drive output, 8 kV rated isolation relay, restrict swap enter, the opposite facet of the optical fiber TX and RX for speaking to the location controller board, and connectors for numerous functions.
