60 volt vs 72 volt

[E-HP]

Looks like I'll either have fun or frustration getting this controller to work once it arrives. The seller sent me the manuals for the controller, bluetooth module and display. Not a whole lot of detail in the first two, and a lot to learn. I see the bluetooth app has settings for flux weakening, although the ebay description didn't mention it, and I don't know enough about FOC to determine whether there should be some parameters in either the app or display settings for that. I guess I have a few things to research before it's delivered.

Interestingly, this link was also included, and on the surface looks like it's for a Sabvoton clone, but the manual actually provides a lot more info on the bluetooth app, compared to the bluetooth manual. This also makes me a little concerned that the new controller could have some issues like the Sabvoton clones have had. We'll see....

Looks like my suspicions are confirmed...



EDIT: Unit arrived defective, so I sent it back. Back looking for more options.

Well since the mystery controller was a bust, I was back to square one researching controllers with the features and flexibility I'm looking for. It's been a challenge, so I decided I'd have to compromise a little and finally pulled the trigger today, picking this one up on ebay:

http://powervelocity.com/home/48-18f-ebike-sinewavesilent-controller-android-ios-bluetooth-programmable-8kw.html

It's more power than I need, but I got it at a good price and has all the features I'm looking for except one...it lacks PAS which is my preferred way of riding my ebike. It does have a Cycle Analyst connector, so PAS is an available option in the future. The IOS/Android app looks great, and I can use it as a display.

So, for the near term, I'll be playing with the new features and using a combination of throttle and cruise control to see how much I miss having PAS. Given this direction, I started researching decent throttles, like Domino and Magura, which are a decent investment in themselves, and the Domino isn't too far away from just purchasing the CA.

So, for folks that own a Powervelocity controller, or any other controller that lacks PAS, is there any other options for adding PAS besides adding a Cycle Analyst?

No FOC?

No FOC?

Yet to be confirmed. I read ElectricGod’s review on the PowerVelocity controller’s, and it appears to indicate they support FOC.

Link?

Is so, that sort of power, could be what I'm looking for, with variable regen. . .

Here you go. No variable regen though. Tuneable (0-200) but not variable, at least from what I see. The interface/app is attractive, with map/gps built in.

EDIT: correction, the settings include throttle braking, so looks like the variable option. EDIT2: looked more closely at the online documentation, and it doesn't look like it's variable. The throttle option seems to govern the controller's behavior at zero throttle, but not variable.

Anyway, this will provide some entertainment playing with the settings and the field weakening stuff, plus I guess now the variable regen, while I figure out which interim step I'll go with while playing with voltages (series packs). When I look at the settings, I don't see anything that would restrict me to the common voltages, so that flexibility is nice.

how has the controller worked for you? are the fets 4110s? when you give it throttle does it pull hard off the line? im looking for a controller like that if its a, power right now from throttle because a car is going to hit me, controller. for 17s

It’s not FOC. Powervelocity controllers are basically sabvoton clones, sometimes with quality FETs.

I say sometimes since my controller blew after some hours of riding. Got a refund so it was handled ok from powervelocity.

Powervelocity Controllers use Sinusoidal Commutation, not FOC (Field Oriented Control). The Sabvoton that I have is FOC as are the PhaseRunners. There's a world of difference in the way they generate sinewaves and in the feature sets they offer.
