3 Phase 250kW motor controller

Posted: 10th May 2020 by iulian207 in Projects


  • Continuous power: 250kW
  • Nominal Voltage: 650Vdc
  • Peak Current: 420Arms
  • Continuous output current: 385Arms
  • Max Efficiency >98%
  • Weight ~ 11kg
  • SD card black box for controller data analysis, via CAN dongle
  • Wi-fi telemetry via CAN dongle.
  • All settings can be user customized. Hardware and software can be also customized according to the client needs.

The controller is using high end Infineon power module making it one of the best efficiency on the market.

Communication: CANbus, serial, SPI, usb for proggraming, open source software based on VESC

Safety: double independent hardware over-current protection. Monitors all phase currents, DC bus voltage, 3 base IGBT temperature monitors. Short circuit protection with gate driver level DESAT protection implemented.

Generates maximum torque per amp across the full range of current and temperature by modifying the proportional and integral gains every cycle to match the direct and quadrature inductances as well as stator resistance in real time.

We are in the beta testing phase of our controller design. It is performing well and we can’t wait to release it. But we won’t release a fully tested product, so we ask for your patience. This isn’t the first high powered controller we have made, but it is the first with a Joule Motors badge on it.
