Which model are you using circuit. Nice to see the scaled up versions of the model 15 diameter motors. Assuming the variants are 30 mm wide stator /rotor, or 40 and 50 mm versions. Looks to be a very nice size for e-bike as the 40 is still narrow enough to fit in between a standard crank setup.

You could try Unitek or MGM Compro industrial controllers.
forget RC controllers. they are not designed for ebike usage and they have no hall sensor support.
i would give adaptto, sabvoton, or kelly a try but first check out the ERPM needed for the desired RPM.
its a shame plettenberg wants so much money for theire stuff and than have no torque throttle controller..

They are no RC toy controllers.

Do the Plettenberg motors use samarium cobalt or Nd?

Ehh... I would talk to folks who've used them before you draw conclusions they can do more than spin a prop. They don't survive any glitches better than any RC toy controller in practice.

Is the IGBT HBC HV series that bad?
I only can talk about the HBC 50063. It pulled several times 9kw with the colossus at the dyno (WOT from zero). But it went very fast very hot, with watercooling attached, due to high switching frequency. When lowered the switching frequency, the temps went down to a level you could use it longer than 10s WOT, but later the low inductance killed it, much below its 500A rating. Anyway I have to say, it was the best RC model derivat controller I tested - no question, also the most expensive..

Under a minute of way less than rated specs before converting your $$$ into plasma is kinda the best case for most of the toy-based controllers. I don't personally have any experience with the IGBT type.
i was afraid to hear such things.. RC toy controllers are NOT suitable for EV vehicles except a few of them when properly used /tuned (Matts Phoenix and Astro Motors).
for EV there is much better and faster phase current sensing necessary and other throttle control.
imagine following situation:
a RC heli or RC plane with its prop on the motor instantly from zero to 100% throttle
the current for spin up or accelerating the prop / rotor is not much higher compared to current under load because of to very low inertia.
an e-bike or e-vehicle needs about 10 x the time for acceleration therefore much higher longer lasting phase currents which needs to be tamed.

I asked for a quote on some of their products... and asked about the magnets..
They use Nd magnets... a little scary for such expensive motors.
But I guess they are needed for the high power density they provide.
Their controller is supposed to be good about cutting out before the magnets can take any damage. But their controller is also big bucks.

I think the Max-E could be a decent match for the Nova 15. Cheaper then the MST controller.
