Hey PV dude..
I saw a couple videos on youtube of your spinning up motors with the 24fet or another controller.
As many of us know, spinning up an RC motor is one thing.. getting it to work under load is another ;)

I'm wondering what the maximum eRPM limit is on these?
And what is the craziest high speed motor a customer is running.

I want to run an astro 3220 in sensorless. It is said to be 8 pole and will be spun at a max of 5500rpm ( low voltage setup )
Efficiency is everything :bolt:

My first major build: 1.6kW 8T MAC motor on a Trek 4500.
The new all-arounder: Leafmotor 1500w @ 4kW on a Turner O2 full suspension.
The monster scooter: 20" eZee on a Cannondale Semi Recumbent.
Whipper-snapper: ? on a lightweight BikeE Semi Recumbent

The controllers are rated up to 50K eRPM when running in sensored mode.
In sensorless, they seem to have no problems running higher eRPMs.
In your case, your top eRPMs are 44K, so that's well within the limit.

However, I am hoping to have a VESC based controller ready for production soon. That one would be rated up to 100K eRPM and should have better support for low inductance motors.

That would be a game changer, sir.
How many FETs would this VESC based controller have, and do you have any estimates on when it will be available?

I have heard that the VESC v6's upper limit is 150k eRPM, which is just enough to squeeze ~90% of the power out of a turnigy rotomax 150cc equivalent, IE 9000 watts out of a 5.5lbs motor.. :shock:
The old v4.x is said to have a limit of 60keRPM, which would make it a glorified ebike controller.

The first model is using 12 TO-247 mosfets and three shunt architecture (i.e. v6) which provides best possible control over torque and RPMs.

Hello,

I am Interested in buying one of these controllers, i am using now sabvoton, and i am not happy at all with it.

Its planned for a e-scooter 60V60AH battery, peak power about 5kw.

Also the GPS Function is very nice :-)

Where can i order?
