Looking for a perfect motor controller? gather here

Post by Kathy » Jul 04 2013 1:42am

Hi guys,
Have you ever DIY your electric motorcycle? What kind of controller do you use?
We are a manufacturer of sine-wave BLDC motor controller in China, I don't know how the sine-wave controllers are doing in your country, but it is very popular in our place, so please don't consider this post as an annoying advertisiment, I just need your ideas to help us develop. Have you used a sine-wave controller? What do you like about it?

Our controller has below remarkable features:
1. FOC sine-wave controller applied to brushless dc(BLDC) or PMSM ,it is applied to scooter motor and mini elctronic car
2. Minimizing the torque pulsation,achieving non-noise,non-vibration run with great comfort
3. Work efficiently,reducing the heat consumption and extending the mileage
4. Built-in protection: block protection, over-current protection, over-heat protection, over-voltage protection and so on, guaranteering the system and driver safety
5. Status and fault intelligence management provide the information including the run-mode, fault type and so on, LED also twinkle in different way to indicate the fault type, all these make the diagnosis and repair easily.
6. convenient external interface: reversing, cruise, ebs, anti-theft and so on
7. parameters and functions can be configurable by computer or mobile phone
8. CAN bus is optional for meter or BMS application
9. Hall Sensor

We are a new company in foreign trade buiness, and hope to make friends from all over the world. Our price will be very competitive considering the high performance of our product and our responsible customer service.
I am not aiming to sell our products here, but to make several friends who are fans for e-scoot/e-motorcycle/e-car. We can disscuss about how the controller should be? What kind of motor controller do you really need? If any questions concerning the controller, I will joyfully like to help.
Have a good day :)

I can't find any high power sine wave controllers, I'd buy one if I could find one

750watt is the highest I can find

I want 20kw

but would buy a 10kw one

I think a lot of people here would buy a 5 or 10kw one


big bonus if we can program it at home too, change max power/speed etc...

These look good on paper, but has anyone on this forum tested one yet? (the 6Kw/72V one is specc'd at up to 350 phase amps):

http://www.sabvoton.com/products/1.html

Also, they do list a programming guide available for download (the adjustable parameters seem fairly comprehensive): http://www.sabvoton.com/attachment/view/335215.doc

So looking at the product pictures it seems 'Sabvoton' is the manufacturer of the several 'brandless' 'Aliexpress discovered' sine-wave controllers.

Also, will Sabvoton sell direct to end-users in single quantities?

Actually,we sell our brand"Sabvoton" only.and we sell our controller to the end user too.The minimum order quantity is 1pcs,for the moment,we would like open the market,as we all know,sine wave is very potential,but a lot customer cann't see it for the moment,I think with more and more users,people can see the performance themselves.
About several weeks ago ,we obtained a order of 5 units(72V,150A) from Czech friends,it seems he received already,we will get their feedback afterwards.Or maybe he is on the forum too,hope he can see the post. :D

Yes ,in China,20KW sine wave controller cann't not be found,but I think,in your country,there is many though they are very very expensive.we can make 11KW one as the maximum.How about that?
As for the parameters,you can set it at home or else with a computer.
What controller do you use now for your escooter?

I would be interested in 400A 144V or similar controllers.

You say your controller has FOC algorithm and is compatible with BLDC and PMSM. So, if motor's BEMF is not exactly ideally sinusoidal (maybe something between trapezoid and sinewave), what shape of waveform your controller will feed the motor? Do you have any documentation and graphs on this?

Forgive me, I am technically-oriented. I have some questions:

Presently I am looking at the 60V 2kW BL MC because that is the closest match to my current highly-modified 63V 12FET controller.

When I look at the specs and the images I am reminded of a Kelly Controller, especially the physical dimensions – which are gigantic in proportion to common ebike controllers. Also the weight is given at 2.2kg/4.85 lbs. That’s pretty dang heavy for a controller and it’s more than my charger assembly. The dimensions and weight appear to be the same for your 96V 6kW unit as well (and actually – they’re all the same)*.

Also, I’m not entirely comfortable with the expression “and so on” when used as “Product Details”. I’m only vague if I’m trying to hide something. Lastly - the Product Details are exactly the same for every unit*.

Though I appreciate you reaching out to the community directly, as an engineer and integrator I require accurate specifications and precise details. When you get your information sorted, please let us know – and post your pricing structure too.

Best of luck, KF

no prefects allowed. just regular people.

@KF: you can see prices over on alibaba and kathy is the contact there: http://sabvoton.en.alibaba.com/

i think xadmx is the only guy who has bot one of these that i know of. i see they include the programming cable and baby CD with software.

The products below has been our best seller ,we sold many to a lot inland trade company,the technology is fully mature.
Model NO. Voltage limiting limiting
DC current Phase current Over-voltage
SVMC048060 48V 60A 150A 70V
SVMC048080 48V 80A 200A 70V

And our reserch DPT are now working on the 84V,and 96V ,it will come out very soon.

I think 60V,72V is very common in ur country?right? :mrgreen: :mrgreen: :mrgreen: :mrgreen:

So can we buy these controllers immediately or is there a need to wait a few weeks to manufacture?

The motor will be driven by sinewave.Strictly speaking,No BEMF of the motor in the marker was the ideally sinusoidal.I don't have the documents at hand now,but if you want,next Monday,when I back to the office,I will offer you some .
The highest voltage we can make perfectly is 72V,350A for the moment.

Thanks for your valuable suggestions.kingfish :mrgreen: When I back to office,I will work on that.
:oops: actually we have difference in Product Detail,the current limiting ,the overvoltage.but besides that all the functions are the same for our products.customer just need to sort out which voltage and DC max current.
Later I will post our price for SVMC060080(according to your requirement,this one is suitable),with the details u need.
For the dimension,I understood the users' concerns,for 48V,60V, we have 2 kinds of dimension,one is 249*146*64mm,the other is smaller and less heavy ,196*146*64mm.But for 72V,96V,we only got 249*146*64mm.
Thanks again for your truth.

Hi Nanoha,
Yes U can,the manufacturing time is very short,if the technology is mature enough,Normally,after a order is confirmed ,we can delivery it within 5 days.Then it will take 3~6 days to get to the destination by air. :D

I'm sorry I don't get the words "no prefects allowed. just regular people"pls help by a little explanation.
Last time ,our customer bought 5unit of controller,we send them 2 programming cable for free and CDs.For one unit ,the programmable cable will be charged,as these things a little expensive,gerenally speaking,we will charge USD9 for one cable. :D

In need of a controller to run my rewound Turnigy CA120 rc motor, these sine wave controller seem appealing and alot cheaper than the Kelly e-bike controller with same power ratings however, i need to know what eRPM they are good to please...If they are suitable, ill be a guinea pig for us non hub motor fan bois as i have had my vike stading still for toooooo long...shall hold off pulling the pin on a 6kw Kelly until i hear back from Kathy..Price is excellent BTW

I'd be interested in one of these controllers.

I'm currently running 2 bikes at 100.8 volts. Would your 96 volt controllers handle the extra voltage.

Hello Rodney,
I'm afraid it cann't ,as I said before,our technology of the products (48V,60V,72V)is mature already ,they are stable ,of high performance,are able to handle some extra voltage.But for the 96V,we are still working on it,the only problem is we can handle 96V as the highest ,no extra voltage protection.
By the October of this year ,we will figure it out,let's look forward to it,haha :lol: :lol:

Also do they come with software and programming harness?

2.2kg is for the larger one,the small one weighs around 1.8KG,but I am not sure,next Monday,I will weigh it by myself and let u know the number.Yes,they come with software and programming harness,but the programming cable will charge extra USD9 for one unit.as the programming cable is a little expensive .for 3 units ,we can gift one cable for free. :lol:
