So I managed to get my motor spinning, but only up to 1600 rpm. When I ran it on BLDC settings with this controller, it would hit 5000 rpm. What setting should I be looking at to correct this? It also doesn't want to start from a standstill on its own. Gotta give it a bit of a push start.

So I just received my Flipsky 75100 and I'm trying to set it up to run my sensorless Heinzmann PMS080 middrive. I downloaded Vesc_Tool3.1 and connected via USB cable. It wanted a firmware update before it would do anything else so now it's running 5.3 and calling itself 75_300_R2. I configured...

So I ordered a Flipsky 75100 Sunday. PayPal processed payment but I have gotten no email from Flipsky themselves. No order number, no estimated shipping date, no nothing. Sent them an email requesting such information. No response. Is this normal for them?

Nice! I hadn't thought of that. Regen while under sail power. That makes sense

I dunno...a boat with regen might be cool. You could use it going over waterfalls. Lol Thanks for the response.

So all legalities aside, is the 75100 a good controller or not? I'm looking for a super efficient controller with regen to use with my sensorless 36v 1500w motor. It's going on a small kart.

I'm needing a controller with regen for a small kart with a 36v 1500w sensorless motor. I'm considering either the Flipsky 75100 or an L10 Baserunner. Which should I go with? Or am I way off base?

Anyone still sitting on some Heinzmann PMS non-liquid cooled motors? We should talk.

I mechanically weakened the magnetic field on my axial Flux motor by reshimming the stators further away from the rotor. It made way more power than I needed anyway. This has upped the rpm/volt and appears to have improved efficiency somewhat. Possibly due to running 36v on a 60v capable motor.

Turns out the controller was not liking my 36v pack. It would drop out whenever the voltage dropped below 36v. I was under the impression that this controller would work with a 36v pack but apparently not. It let's me set the low voltage limit down to 28v in the programming. Oh well. It's hard...

I tried switching phase wires around at someone's suggestion and also tried a different throttle. No improvement.

I'm trying to use a Powervelocity 12F controller to run a sensorless Ryobi 40v electric mower motor. It'll run up fine to 3600rpm unloaded, but when I put it under load, it starts glitching and jerking at about 2500 rpm and 500watts. Thoughts?

Too bad they have that splined shaft... I'll keep an eye on them anyway

If your pmac is more powerful than you need but running too low a speed, you should be able to increase the speed and lower the overall power of the motor by increasing the airgap between the stator and rotor. Not too hard on an axial flux motor, more difficult on a radial flux Not sure which...
