whereas I have few teeth.
It's not that I didn't brush/floss. I wore out the enamel on my teeth before 50y, but I was also born well before fluoride was added to water supplies. My sister (born after fluoride) still has her teeth and my younger brother had his but my older brother suffered the same fate as I, except he can use dentures while mememe, having 3 sets made and rejected, can't.
Maybe I'm suggesting flouride treatment is [marthe s.]"a good thing"[/martha s.] or maybe not.
*************************************************************************************
I ordered a LCD3 panel some time ago, but shipping by slow boat means it will arrive sometime during December (est. 2 to 22 Dec).
The motor is far more aggressive using a 22A square wave controller over the KT36 26A sine wave thingy, so I'm guessing the KT36's various settings are needing different settings from what they currently is. Still, the mini geared hub motor had more pull on grades.
Average power use for going shopping shows 20W, a wash, and the DD motor gives 20MPH with a 12S battery.
3MPH faster than the mini, whew!
However, the DD struggles up any grade...

Most of mine have damage; probably lost a third completely (except the shards of edges still in the gums for the molars) (and another one going now; at least the heavy garlic/vitaminC over a couple weeks stopped the infection). I drank the flouride-water and it didn't seem to help me, but my family has generally bad teeth anyway.

Sounds like the DD needs more current...or it's just not a wide-enough stator/magnets inside to give the torque needed at the current it's already got.

(and phase current is different from battery current, though usually more battery current also gives more phase current).

I do think it's interesting that the DD motor reacted a bit stronger while being controlled by the 22A square wave controller over the 26A sine wave one.
The anticipated LCD3 should tell me why once it arrives, since I currently have no other way to check the sine wave controller's settings and really, because the rainy season has started here and I find myself less tolerant of working outside (even if it's inside the workshop) while it's raining.

...and since I donut has to do anything if I uncomfortable, I don't.... advantages of retirement.

Got the LCD3!
Connected it up and powered up the system and ended up having to mount the panel and the switches.
After doing so, the fog lowered and The Big Chill prevented me from accomplishing anything else (which I suspected might happen and why I mounted the panel in loo of unplugging it after I finished with the setup)

Next opportunity will be on Friday (maybe)

yep... these KT controllers use a BIG (and quite empty) box. About twice the size of the infinitron 6 fet thingies.
The only thing good about the box is it has a lid, making disassembly and reassembly a piece of cake (with extra frosting) compared to the various 22A and 30A controllers I have, now sitting on a shelf.
******************************************************************************************************************

I managed to be warm enough to work on the trike and even made a shopping trip. As I suspected, the controller really needs the LCD panel. The motor now reacts how I thought it should, given the 26A rating.
Haven't figured out how to set regen or the fact I use 12S (44V) battery packs. The display shows the battery being half-empty (or half-full, your choice, mine is usually along the lines of "how much?")

Display indicated 50kph, but then I remembered I haven't set the wheel size, where the packaging indicated it was preset to a 26" wheel... and I has a 16 incher. Wheel, that is...

So, to set the regen on the new controller I had to cruise Utube... which was hilarious, as the usual spokes person would say "refer to your manual" whereas MY manual mentions nothing about parameter settings.
Finally someone mentioned "C13" being the regen/ebrake parameter, qualifying with "refer to the manual" for settings. Hilarious. :(

Same with motor current and other, important settings that my manual doesn't even mention.
But hack I will and now the motor no longer bogs down on any grade, the regen is set to its' strongest setting and I can read my battery voltage from the panel (as I can just look down at the battery to read its' voltage and Watts consumed, this last panel reading is redundant to my needs)
Since I AM lazy I will use the panel in loo of having to mount an on/off switch for the controller.

I think you want this manual.

thanks! Here has a picture of gulls, which was funny as a loon kept calling out but the only birds I saw was these gulls, cruising around the harbor. Too be added after I figure out the problems


yep, could have looked for the manual, but I currently lack a computer in the workshop so having a file with no printer is kinda... discouraging... and hacking around things is what I likes to do :lol: .
If I sound like I'm complaining about something,well, I'm a cranky old man who's only enjoyment is complaining about ever lil' thing
*************************************************************************************
notes about the controller (KT36):
- Although I turned off the cruise control it keeps turning back on upon power up, and I HATE how it works!
- The strongest setting for regen is actually a bit too strong, taking this heavy trike to a (almost) complete stop down a 25% grade. I reset it from "5" to "4".
- Also reported by other users, the motor makes a weird grumbling sound as it accelerates from a stop... almost like the sound of the grumbling cranky old man operator!

Every time I hit regen initially there's a "clunk" from the front. Investigating the issue shows nothing external could be causing the sound, so Imma just gonna assume it's the motor itself, going "clunk"... a clunky issue indeed!
less see if the image issue is fixed:

Is your motor mounted on the front? If so, I wonder if the axle is secure in the dropouts and torque arms. You could be hearing the motor shift as regen is applied. I'd say that that would be "not good." If there is no motor in the front, then I have no clue about the noise.

Yeah, it's in the front fork:
Image


The clamp looks good, but it doesn't take much movement (rocking) to make a thunk.

It's also possible but unlikely that the axle on one side is cracked thru and so it's rocking on that side--this would probably result in other problems you'd notice, like rim brake alignment issues, etc. (but it can happen; it did to my X5304's axle though that's after unknown years of use (or abuse) before I got it, plus my own abuse of it on the trike).

Or perhaps the fork's steerer is not tightly seated between the bearings in the headset? That would make the front "thunk" (it does that for me on my bike and trike when the headset problem occurs).

It could also be the windings on the stator core itself: If they are not tightly wound, they could "slam" around from the sudden change in magnetic force directions and amounts. This isn't very likely, but it is possible. I don't know what sound that would make, but I'd expect a grinding rather than a single thunk.

Having ridden and fixed issues on bikes, trikes, scooters and motorcycles for about 60 years, let's just say I've experienced every front fork issue imagined. I investigated these possibilities several times now, and the telling argument is that there is -0- vibration felt in the handlebars when the sound is made. (more of a "thunk" than a "clunk")

Come to thunk of it (yep, j/k)
I've heard this sound once before in my life some 40 years ago, coming from the windings of snubber transformers used in a particular manufacturer's 1000W dimmers... also with no vibration felt!

but the bigger issue is why the forum software rejects some image files for, what I can see as having no issues whatsoever, beings they came from the same camera, manipulated (resized) by the same software,and emanating from the same file folder.

It's difficult to get zero shift, esp. with regen. I have a rear wheel setup with a big torque bar, but no matter how much I tighten the axle nuts there's a little "clink" when I go from regen to power as the axle shifts a fraction of a degree (before the torque bar keeps it from shifting further.)

That's why i suggested it, cuz I've seen (heard) it happen on various wirewound magnetic stuffs. :)


but the bigger issue is why the forum software rejects some image files for, what I can see as having no issues whatsoever, beings they came from the same camera, manipulated (resized) by the same software,and emanating from the same file folder.
If they're all the same dimensions, and below the image file size limits, I don't know why they'd be rejected either. I haven't uploaded much since the forum downgrade "upgrade" but if I see the issue I'll poke around with it till I find out why.

Or if you wanna email me the files that don't work along with a few that do work I can poke at them to find any differences. Just PM me for email address. :)
