KT-LCD5 settings for use with an Ananda 20" 250w 36v front hub (unable to find motor specsheet)

Hello everyone,

I have replaced the controller and display on this e-bike because the original Ananda MC5-B0 controller fried itself very quickly. I went with an 15A controller and the LCD5. I have tried setting up the controller as best as I can but I have no clue what the torque ratio is or how many magnets the (20" front-wheel) hub has. The motor claims to be an M5 motor also from Ananda but I cannot find anything when searching with that parameter. (This setup has a HAL sensor, and should not throttle at any time but only do PAS)

The way I have it set up now I can hear the motor making sound when PAS is supposed to kick in but it doesn't actually seem to assist (just whirr pretty loudly) so I am unsure.

This is a dump-out of my current controller settings.


Can you guys tell me more perhaps?
 
You are going to have to get hold of the motor specs so you can fill some of these items out. Particularly P1.

P1 = Motor Gear Reduction Ratio × Number of Rotor Magnets
Rounding to a full number is necessary. The P1 setting ranges between 1 and 255.

Do you have a controller manual to explain what all these settings are? All KT controllers pretty much use all the same settings so any manual for any of the KT displays will do.

The manual I have used to set my P and C parameters is this one (which actually is for an KT-LCD8H but both the LCD5 and LCD8H use the parameter from the LCD3 ('LCD3-protocol').

Regarding the motor, there is litterally no information or even any other refferences to be found online so I'll need to manage without the spec-sheet. Is there any way that I can measure or calculate the values which normally would be found in the spec-sheet? Else I think I might be sh*t out of luck...

I personally use several of the LCD3, the LCD8H and a couple of LCD4's. Since they all interface with KT controllers, and those controllers all have common settings, one manual will work for all of the models.

But the quality of the translation is often horrible. Google the Dillenger KT-LCD3 manual and you will find one rewritten by a native English speaker. Maybe thats where your problem lies and you just can't figure out the meaning of the settings.

To calculate the P1 setting, you would have to have the motor specs to determine the gear reduction value. An alternative to this would be to open up the motor, count the gear teeth and google up how to manually calc the gear reduction values. Then you count the magnets and thats how you can manually arrive at the P1 setting.

I looked up my Bafang G060 and G020 settings for KT controllers, and both come out to P1=100.

If the Ananda motor is not compatible with a KT controller, then indeed you may be SOL.
 
So these are the only things where we could ID the motor with, and so far I'm striking out 100% of the time. I'm gonna write both Ananda NL and Ananda CN with a request for information (but doubt that I will get this),

So no spec sheet, tried opening the hub but the screws are so soft they strip even with the right size of torx, anybody got any ideas at all what I should do to figure out the magnet count and gear ratio? (if not I migfht just tweak the value untill it's what I would assume the right one.
 
Some motor manufacturers use red loc-tite to fix the screws in place. One time I had that and Phillips head screws. I had to use a heat gun and then an impact hammer to get them out. The manual impact hammer delivered force down as much as it did to the side which kept the heated screws from stripping, after I heated the bejesus out of the motor. Needless to say it helped a lot that the motor was not installed in a wheel, doing all this.
