Good thinking. The sudden current draw could be causing a spike or dip in the throttle signal voltage triggering a fault. I'll try and adjust or disable the throttle fault detection. It seems weird that its only in square mode and not FOC. I wonder if FOC has a slower ramp on initial start up. There...

Repeated the auto setup with the new Pid settings. No change. I'm still having the same issue.

I also tried using square mode and reducing the amps/sec ramp and it still does the cut out fault at full throttle from a stop.

Any other ideas?

Dirt jumpers geometry suits well to build ebikes, but their nimble handling is not particularly suitable for high speed. You’d want it long, choosing a longer wheelbase or stretching it with custom, 3 or 4 inch extended dropout plates that would place the rear axle further behind the seat tube. The...

I can handle packaging the drive in a durable fashion. I also agree that a hub is out of the question for this. I only mentioned that the bike will be powered to drive home the point that pedaling geometry and ergonomics while seated are a non issue here. Seems to me that the majority of complaints ...

Would a dirt jump frame make a good mid drive bike at high speed on trails? Would a dirt jump bike be the perfect solution for a durable playful geometry but still do well on trails at high speed? Seems like the major drawback to Dirt Jump frames for trail use is the seat tube is usually very low so...

Bummer, the amps/sec is the fun part. Are you using FOC mode? Where are you currently set at regarding amp/sec and total phase amps?

Here is the problematic config file if anyone wants to take a look at it.

I had a similar issue with my LMX64 when I first got it after increasing the amps too much. Weirdly, since I did a firmware update I was able to set the amps high again and now it doesn't do it any more. So maybe do a firmware update? Cheers I believe I have the latest firmware. I'll double check. ...

If any of them would be willing to send me their calibration file that would be great.

Im using one of these newer style 46kv 30mm Lmx motors with a nucular 6fet. It runs pretty well in FOC but growls and sounds like its losing sync at full rpm unloaded. It also has a slight stutter when i gently apply throttle from a steady cruise. Do you have any tips or a config file you could shar...

Adam, Im using one of your new style 46kv 30mm motors with a nucular 6fet. It runs pretty well in FOC but growls and sounds like its losing sync at full rpm unloaded. It also has a slight stutter when i gently apply throttle from a steady cruise. Do you have any tips or a config file you could share...

I guess it depends on what you consider "wrong". It's well documented that this model of motor has trouble with sine wave controllers. It even says on the LMX website not to use it with sine wave controllers. So I don't think my personal motor is broken or defective. I'll reach out to the other user...

IDK. The motor is perfectly smooth in Square mode up to full rpm whether loaded or unloaded. It also works fine with square wave controllers. Its efficient and stays nice and cool even with me being really hard on it. I would just run it in square rather than FOC but square does this fault think whe...

It still does it with no FW

I made a small board with capacitors to clean up the hall signal on an rc motor. I'm going to run the auto setup calibration with that In line And see if maybe it helps.

Does FOC use halls at all?

I did not. I'll try that.

The good news is that it pretty much rides great and is very useable. I just dont want to burn up anything with amp spikes if it loses sync. Seems pretty innocent.

Tried the settings listed above. It got better at the low load transition stuff but still makes a little audible growl when I sneak up on the throttle from a roll in FOC. At full rpm unloaded it sounds terrible. Lots of growl and stutter like its loosing sync. In sensored square mode or combined mod...

Thanks. I'll try that config on mine and see how it runs. I'm not sure what you mean by nails. If it was a hall glitch would running in sensorless mode help? Right now it runs poorly in sensorless mode. I have to be very slow with the throttle To keep it from stuttering. In square mode it runs great...

I was just hoping to understand what it was since integral constant in PID loop doesn't mean anything to me at this point. I did try changing it to 100 it was at 200 as shipped from Vasiliy. The motor is still stuttering really bad at full unloaded RPM in FOC mode. I did notice there was an FOC Ki i...

Im having a similar stuttering issue with the small LMX motor which is similar to a cyclone. I'll check my DCi Ki setting. Can anyone explain what that is? When changing it from 500 to 100, is there some significance to the value of 100 or is decreasing incrementally until the stutter is gone a bett...

Thanks.

Did you get this resolved. Mine is doing the exact same thing. I'm using the 46kv 30mm LMX motor which is similar to your cyclone. Mine stutters really bad when I barely creep on the throttle from a roll. It also does it really bad when the wheel is at max speed when off the ground. So its definitel...

BMS is like a tiny balance charger that stays connected all the time. It offers the protection of LV alarms because it will cut the main power off if any one cell has problems. They offer high V protection At the individual cell level while charging as well They generally offer short circuit protect...

There is a frustrating lack of pre-charge in the electric motor controller world. I wish it was a built in feature across the board. If you are not clear on the precharge thing its basically a method for keeping the spark down at your connectors or the contacts of your main contactor. The cpntactor ...
