Just wanted to thank lyen for a great controller and communication on the above sensorless controller.
Got mine today about 10days after ordering from the US to the UK. No customs charge.
But the difference is you can ask lyen to spec your own custom controller before it hits you door. Making it all the more worthwhile.
Quality of the controller is very good and it really is mini.
It's mostly the depth that is surprising.
I wanted a controller to work at 12s lipo and 18s lipo on a sensorless bafang bpm.
This controller has given me that flexibility and maybe later on 24s if I feel like hiring out the motor, gears and clutch.
The connections are the same as my 9 fet sensorless controller so setting up was a doddle.
12s throttle is smooth and the sensorless works well. The controller is currently set at 30amp current peak. So about 7amp higher than my 9fet.
18s the thing is a different bike. Hideously quick and some slight delays on the throttle response. I've been on it this morning loving it and love the flexibility to choose range or speed. My legs can just about keep up with the bike on full pelt.
The bpm is wound for a 24inch wheel but I'm running a 700c wheel. It's a hard tail. So I can now see why so many of you opt for the full Sus wider tire bikes.
Still very fun, not sure how long the motor will last at that voltage or current (now pulling peaks of 2000w) and the motor actually becomes warm for once. At 12s 22amp it never got warm at all. Think because I'm using a hybrid bike in amfairly flat area it just doesn't push it.
Anyway great controller. Well worth the buy.

Thanks for your interest in the controllers. PM sent.

I emailed this to you on Sept 10, Aug 23, and PM'ed you on Oct 1st, but no luck. I hope all is well as you got back to me right away on previous occasions. I though I'd try you here as the next best spot.
I never did get this working. I tried all your previous suggestions re lowering the current as well as changing the hall space angle. At best I could get a stuttered take off which became better as the speed increased. On your sensorless motor I tried each 60 and 120 hall angle with the six phase combinations, and still no luck.
Maybe I could send you a Cute 100 motor so you could test the settings yourself?
Original problem from July 3rd, 2013:
I thought it might have something to do with the hall space angle degree but I didn't know what to try. I never thought about lowering the current. That might be it too because bmsbattery says that their more powerful controllers are not recommended for the cute 100 motor.
I will try both your suggestions and let you know if you need to update your motor database with anything.
From: Edward Lyen
Forgot to mention that other thing to try is to manually change the hall space angle to 60 degree or 120 degree in the program.
You could try to lower the current settings.
