3 Phase motor controller

3Phase motor controller PMSM
3 Phase motor controller for Permanent magnet Synchronous motors


Nominal Voltage 700Vdc

Current: 300 Arms

Max Efficiency 99%

The controller is using Si`C as power module making it with better efficiency than IGBT controllers.

Communication: CANbus

Safety: double independent hardware over-current protection. Monitors all phase currents, phase voltages, DC bus voltage, DC bus current, 2 stator temperature monitors, 2 base plate temperature monitors.

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 an unfinished 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. There is ONE opportunity for a first impression, so we will get this right. In short, we don’t know when it will be released or how much it will cost yet. When we know, we will let you know.

Motor parts arrived !

    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.

    i like the motor
    where can i buy it?

  3. i like it
    it is very good, thank you

    Please I need 1v-700v Senseless BLDC Controller 1A-5A capability, Frequency range upto 10Khz

    can you help.

    Thank You

    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
