I did not try this one but this is big heavy tire - 100/90-19 compared to say 3.0x17

Nice. Good news. Your halls are fine. I also find 120 specified everywhere next to Sabvoton. I don't know about determining hall angle in a motor. I would be interested to find out how to determine it. I mostly used qs hubs and sabvotons controllers therefore and never had a need to figure it out. U...

What's hall test outcome when resistor added? That explains why results are different when measured with controller connected and making test with external power source.

I have a custom build project I'm working on. The question I have is then is it possible to put a 110/80 -19 M/C 59S TT on a 20 inch bicycle rim instead of the. 19x2.5 motorcycle rim it says. I'm building a chopper bicycle with a electric wheel hub on front tire and this is the tire going on the re...

It can be that old controller is sensorless.

Halls can be cooked by static charges or when (if) it connected to phase wires accidently.

Yes, seems broken halls.
The strange thing is that all three are broken instead only one.

BTW I searched your old controller in internet to find out if its sensored or sensorless or both but can't find it. Not long ago I had some motor with faulty hall(s). When connecting it to Sabvoton I would get "hall error" without needed to touch/spin hub motor. I did this controller conne...

I watched your video several times trying to figure out where is the catch, why there is no any output signal from any three halls ie yellow,blue,green signal wires. One thing pop up into my mind. Why to supply black/ground ("-") to controllers halls connector. You can supply "-"...

I've tried high amps, for 50A for test and it worked for me the same as 15A. So I think yes, you can trie high amps.

Maybe your old controller can work in sensorless mode and halls are faulty indeed. Or maybe halls partially broken and your old controller can work with it and Sabvoton can not. I'm saying because I know you tried various phase and hall combinations. I hope your tried correct ones. Even with correct...

This is for my new motor which has no temp sensor installed yet.

Well, I found out that I can't use a any temp display. Someone had experience mounting external temp display with some kty inside a motor? Also sabvoton is tied to KTY83/122. Installing different kty sensor temp will be off. Resistance at 25C should be 1010ohms typical. Assuming can't source the sen...

I did not plan it but few hours ago some guy arrived for advice with few motors and one of these looks like 273. I gave him new 205 and got this one, swapped. Both hall pairs are faulty. Peeked inside, looks clean, like new. Unfortunately don't have pics of inside. Tire looks unused at all. I wonder...

You don't need to oplogize nor am I offended. I might now remember how to spell pull vs pool and use it in proper way.

If you have no idea than context makes no sense to you. Pronounce the word and find if sound assimilates to something meaningful to you. Appearantly word is: pulls. It can be substituted with other words like thrust but even with correct spelling it might be complicated. I am trying to also help yo...

Exactly how it is. Fast wounded hubs needs lots of amps to achieve similar thrust, also small diameter light wheel helps too. Mostly folks have Kelly's Sabvotons or some similar cheaper controllers in 80-150 amps range. Also batteries in frames mostly are 18650 in 100 - 300pcs which have certain lim...

Meaning accelerate I guess, but wrong statement. Slow windings of the same motor don’t have any more torque starting from a standstill. They just require less power to achieve their optimal acceleration, but fast windings can be fed more power, for a longer period. So, acceleration is more economic...

Please find a better English word than "pools" for that meaning, no idea what you're trying to convey there If you have no idea than context makes no sense to you. Pronounce the word and find if sound assimilates to something meaningful to you. Appearantly word is: pulls. It can be substi...

If you can get 273hub easier go for it. Both have its own good and bad sides, nevertheless I did not hear unhappy 273 owners. 205 are happy too. It's just good powerful motors. Yes it is heavy. You can't jump high with it. On obstacles rear wheels goes in the air, it bounces little bit, but good sus...

Out of interest. What was your Flux weakening setting ?? will check later @overclocker: where did you buy from? qs-motor or SIA/Ecosys qsmotor (www.cnqsmotor.com)? whichever it was, seems their delivery is worse than i've experienced aren't those 2 the same company? here in philippines importations...

If person does not reply for so long it means he is not well, might be on sick leave. Try his colleague.

Hi,
I want to see temp on A display from KTY83/122 sensor in hub.
What display (thermometer digital lcd display) is compatible with this hub?
Or I can get any CN cheap display and adjust readings through resistor.

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...

Nop.
