VESC controller for high power systems

This is the hardware repository of a 3 phase inverter brain, UNTESTED but designed with the following specs in mind:

  • Compatible with VESC firmware and software tools
  • Embedded security features (overcurrent protection, pwm overlap elimination, etc)

Microcontroller

The core of the system is a 32 bit ARM Cortex M4 MCU (STM32F405)

Communication interfaces

  • CAN bus for control, configuration and monitoring
  • USB for light usage, firmware upload/upgrade and configuration.
  • UART, I2C and ADCs and GPIOs available

Motor inputs

  • Bus Voltage (differential)
  • Phase current (differential)
  • Phase voltage (differential)
  • Gate driver fault
  • Power_good from gate driver
  • Motor temperature
  • Hall/encoder
  • Resolver

Gate driver outputs

  • PWM high/low
  • dynamic gate drive current (pwm)
  • 24v power
