3 Phase 250kW motor controller

Very lightweight design, water-cooling.

Specifications:

  • 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.

    Looking fwd to a release. We need at least 450 volts, 100 amps continuous. We like using Hall sensors but could change to encoder. Our motor has an almost sine wave back end.
    Great work…congrats on using siC seems to the future.

    Salut Iulian,
    Ma poti ajuta si pe mine cu o idee pentru un contoller de AC? Am o masinuta Aixam Mega City Electric cu un controller SEVCON Gen4 pe care nu il pot programa.Am vazut controllerul tau si ma intrebam daca s-ar potrivi pentru modelul meu de masina.Originalul avea 48V la 450A si un encoder A B care din cate am citit ar avea 61 pulsuri/rotatie.Sau daca ai o schema testata pentru un model de controller AC? Multumesc mult
