Re: Sabvoton SVMC072150 controller review, variable regen *PICS*

Hi, guys what did you find about this 3-wire connector (red, brown, black) for the 0-5V brake ??? What do you mean what we find. This is connector for electric brake. Use it to stop your ebike. I also have the controller with a 3-wire connector (red, brown, black) for the 0-5V brake but when I conne...

How to solve undervoltage error 00000004?
Setup bough very recently. CAN version controller.
You seem to be in Park mode, locked controller. See earlier posts for fix.
I will look into it. Will read through posts.

Re: QS 3000w midmotor

different pitches, different lengths, see pic. more tooth does not mean less noise. Unless you install bigger front sprocket and motor rpm drops down, so yes, there will be less noise but mostly because lower rpm, but less mechanical advantage which is opposite what is aimed. Noise is created by cha...

Re: QS 3000w midmotor

72T and 12T will give 6 ratio. 72T and 10T will give 7.2 ratio. If it is too sluggish from start, change it to 10T later on. It all depends on rear wheel diameter and tire selection and amps supply. Or in between with 65T and 10T - 6.5 ratio, but with 72T more freedom to change gearing later on. The...

Re: QS 3000w midmotor

nucular 24fet (500A phase, 300A battery) is very enough, but up to 20s (90v). Maybe can be 21s, need to ask if is safe to go near top values on this controller, also it might depend if you use regen braking. Regarding splitting modules or not. If you can accommodate unsplitted modules into frame and...

Re: QS 3000w midmotor

Everybody will have different opinions about it. It will be a weak if you want to pull wheelies at 100km/h. It will be strong to spin wheel in low speeds if geared correctly. The lighter the bike the better performance. Also take into account that it is not just motor which gives you good performanc...

Re: QS MOTOR,0.5-14kW Electric Hub Motor Manufacture China

It's very good that you stated that cleary because I think I and probably others assumed that slower motor needed, less rpm are need, something like 4000rpm with field weakening when building bigger wheel ride. I totally believe with higher reduction you might win some more torque on rear axle. I th...

What rpm you aim for? What's wrong with current, max 6000rpm with field weakening.

They don't do customisation if not plannet to do so. And they did not plan to do custom winding for the motor.

Cant seem to make my controller run slower changing the DC currents and the phase currents, only works when changing the motor speed percentage but this makes the motor run hot, any input would be helpful I’m running a 96120 controller Run controller slower?

People are having controllers like Sabvoton or Kelly or some Infineon etc. Controller is very important factor in how much thrust you wi...

Re: QS 3000w midmotor

Current floods motor with more current when field weakening kicks; motor does not converts it to mechanical energy and more heat is happening. If temp is not monitored that something will burn. At least with cheap controllers it is. Just poor controller design.

Can use sabvoton even though qs does not recommend it for the motor. It will run but I don't know if field weakening will work as good as with votol.
Also I think sabvoton does not run sensroless.
