QSMOTOR,0.5-12kW Electric Hub Motor & Mid Drive Motor Manufacture China

[BCTECH]

Vito,

Would you be able to sell a kit with sine wave controller and motor with 135-140mm dropout to reach 70km/h on either 48v or 72v?

I need decent speed but also very good torque as I have some hills to climb.

Thank you

Vito: We could provide motor with sine wave controller (e.g. Sabvoton Controller SVMC072100).
Here is the link of controller for reference.
http://www.sabvoton.com/product/72v-4kw-brushless-motor-controller.html#.VWuufiOQvSw

For dropout of motor, we could only make it above 150mm (include 150mm) for 70KPH, and we could to make it 72V.

Best Regardfs

I think the Adaptto mini-e should work? around 1kg and give your the speed

As a vendor this level of detail can be used to clearly demonstrate the difference between the older model 273mm stator motors, and the ones I've heard rumors about that have significantly fewer poles in the same size stator. It may not be understood by the vast majority of customers, but that is changing here on ES.

Hi John. Could you pls explain that part once again, I am struggling to understand. Will the new version have fewer poles?
And how does that affect the efficiency of the motor?

Yes it would work... but at 546usd just the controller it's out of my budget. My bike will be parked outdoor overnight everyday.

I will suffer from vandalism and need something that isn't too costly to repair and replace.

I heard from member here needing to pay 200 usd to get the controller repaired. I can't afford that

i am also interested in this info.

here is a quote from a pm reply to a question i had re. tooth count effect on performance..from a member we all know well-

"What i think for the stator tooth count is that higher tooth count help at very low speed for taking off as the cogging is less important, but for higher speed the lower tooth count might be better, but that is only my opinion ......
maybe asking to Luke or SAFE or John in CR would be the best answer about the lower tooth count on that V3."

 

[John in CR]

Guys this isn't my thread. I simply prodded Vito to talk about their latest, and provided the tools in the form of simple motor measurements that clearly show differences between motors.

BTW, no, a high poll and or slot count has nothing to do with better startup performance.

I've been enjoying my QS 205 motor for a little while now! Just for some speed data points:

205 4T motor with 19in JRH rim with Shinko 241. Adaptto Max-E on 25Ahr Turnigy 20s lipo, only running auto-detect 3 times (no manual tuning). Vector bike frame. I ended up at 50mph with no OVS timing. I hit 55mph with OVS at 3 and stopped, it may have been at the fastest, but I was pushing my luck and shut'r down. Lots of fun torque (<40mph), definitely not insane, but enough to have fun.

Thanks Vito!

EDITED: 65mph no OVS on 20s Max-E with further tuning manually.

[QSMOTOR]

Thanks for your answer. I know Sabvoton controller but they feel a bit big. I need a controller of 1 kg max and motor of 10kg max. Top speed around 60-70km/h.

Any way I could have that?

Thank you

Vito: Sorry, I think not. As we don't have such motor and controller yet.

 

[cwah]

what is the weight of your V3 motor with 50mm magnet height and 2000W? thanks

 

[QSMOTOR]

what is the weight of your V3 motor with 50mm magnet height and 2000W? thanks

Vito: Net Weight of QS 205 V3 50H 3kW Hub Motor is about 12.8kg.
I don't have weight of QS 205 V3 45H 2kW Hub Motor, it might be 1kg less.
If any news, I will post in thread.

Best Regards

Here attached one test report for your reference. (the test have not finished)

16inch 8000w motor 1200rpm, with 96600 controller test.

Max. input current 180A
max. Eff.: 90.6%
max. power out: 15380w

 

[atomek1000]

I would be interested in cheaper alternative to sabvoton. I need only 80A of current and 48-84V will be fine.

Do you have something to meet theese requirements Vito?

 

[Doctorbass]

That is a really interesting controller Vito.

Can you let us know what FETS are used inside for the output section?

IS there any SIN/COS version instead of Hall sensor?

[litespeed]

Looks good but really wide for an ebike specially the way the phase wires come out the side.

Like the sound of the price and power.

[Hyena]

Very interesting, I'm keen to try one. I've been hunting around looking for a controller to adequately power one of your new 273 8kw motors for my upcoming e-moto project and this looks like just the ticket!

Can you confirm if it has variable regen braking ? I would assume a controller of this calibre does but it doesn't expressly mention it and while the pin outs for the throttle show a variable voltage range I can't see one for the brakes.

Looks good but really wide for an ebike specially the way the phase wires come out the side.

Trying to put this on anything resembling a bicycle would be stupid. You're talking about nearly 30kg of motor and controller alone then another 20kg atleast for the batteries. This along with peak power around 30kw is proper motorcycle territory.
That said, the design could have been a little better. It's not even so much that the phase wires exit from the side but that 3 of the 4 sides will have fat bunches of wires coming out from them. It makes trying to integrate this into a bike not so aesthetically pleasing...

Hey Hyena, pay attention to your words! Luke installed about 50kW on his famous death Bike and we all have respect for what performance he acheived with that :wink:

The Adaptto Max E can do 160A batt and 400A phase easy and we all love it for bicycle

This new 200A batt 600A phase controller is like a Sevcon size 6 but in a cheaper way... .well 4 time.. but not the same quality but still very interesting!

The continuous power of about 5.5kW and burst of 16kW ratio is strange.

I agree with doc.. i was looking at some sabvoton controllers the other day..

one was rated at 6kw continious.. 10.4kw peak .. and there higher voltage version at 7kw continious.. and 14.4kw peak..

i'd be willing to try one of these out to see how they preform, i've sent a pm to the seller..

Luke is the exception to the rule
You and I are among the few here who have gotten to play with his toys and we both know what the famous death bike is and isn't :wink:
I was more referring to the trend these days for noobs who come along and want the most crazy power possible strapped on their cheap walmart bikes. It's all too easy now to get a cromotor and max e and jam it onto anything that it vaguely fits but obviously if not done properly it's not going to end well.

The Adaptto Max E can do 160A batt and 400A phase easy and we all love it for bicycle

Yeah they're great, for sure, but this controller is double the power again. I'm all for pushing the boundaries of what you can technically slap pedals on and call a bicycle but bolting on this sort of power and the necessary battery capacity to make it useful for getting around and trying to pass it off as a bicycle is a bit cheeky

The continuous power of about 5.5kW and burst of 16kW ratio is strange.

Where did you get those figures from ? With 275A rated burst current and ~100v under load that's more like 25-30kw peak and from the graphs and construction it looks like it could do 10kw+ all day long.

Like many of these controllers I think they rate them like that for heavy duty e-moto or e-car use. As above the adaptto max e can spit out some big numbers but only in short durations - which is fine for ebike use. If you try and drive a motorcycle with one at speed where they're pulling 160A continuously they're not going to cut it.

Vito, any chance of a look inside the case ?
And +1 for Docs previous question about what fets are used.

Hi, this is Cherry, Vito's colleague. We use the same one account to publish our products.

For this brand controller, the current from 40A to 200A. We sales the 200A now, for small current controller, due to the big controller size, we are on improvement.
The final type will coming out in the August...


Btw, we have competitive price for Sabvoton controller, maybe you can consider about it.

 

[Hyena]

Welcome to Endless Sphere.....we over volt and over power everything. :lol: you are obviously a new guy!

Thanks, yes I just signed up. I'm looking to build a bike that does 100km/hr with a 50km range for $1000. I have an old walmart bike that I will use. It only has V brakes but it's still a good bike. Also does it recharge when I pedal ?
I get emails like this every few weeks It was the likes of them my comment was directed at. But ES is to blame :lol:

Oh...by the way I've been here for almost 5 years!

Time flies huh ? I just looked at my own profile thinking I'd be about the same but I'm coming up for 7, and Doc and Steveo are around 8!
Damn... who needs drugs

Hello Doc,
This is Cherry, Vito's colleague. We use the same account to publish our products.

For 96v controller, we used MOSFET IR4115, 36 mosfets
I'm not sure your meaning on "sin/cos version", the controller I listed is Hall sensor, sine wave controller type.
