Compatible E-Bike Controller with: S-LCD3 ?

Hello,

I've looked at BMSBATTERY.com for a Controller for the Q85 Rollerbrake Motor.
I have this motor: https://bmsbattery.com/ebike-kit/437-q85-36v250w-roller-brake-front-driving-hub-motor-ebike-kit.html?search_query=Q85&results=13#/rpm-328

I'm looking for a controller that is suitable for the following display:
https://bmsbattery.com/ebike-kit/670-s-lcd3-lcd-meter-for-s-series-controlers-ebike-kit.html#/color-black

And that I can maximize the Q85 motor (40 - 45KMH)
(25 TO 28 MPH) Q85 WITH 328 RPM. (More is better)

I've seen the following controllers, but do not know which is right for me and meets my requirements.

1. KU93 450W 9Mosfets High Speed Controller (LED 810)
https://bmsbattery.com/ebike-kit/363-ku93-450w-9mosfets-high-speed-controller-ebike-kit.html#/led-810

2. S09P 500W Torque Simulation Square Wave Controller

3. S12S 500W Torque Simulation Sine Wave Controller
https://bmsbattery.com/ebike-kit/552-s12s-500w-torque-simulation-sine-wave-controller-ebike-kit.html

4. S12SH 800W 35A Torque Simulation Sine Wave Controller
https://bmsbattery.com/ebike-kit/667-s12sh-800w-35a-torque-simulation-sine-wave-controller-ebike-kit.html

Can you tell me which controllers are suitable for this high speed and work on this type of display?

What type(s) controller are compatible ? (1,2,3 or 4) ?

And what are the differents off: Sine Wave, or Square Wave controllers ??
What type is better ?

Thank you.

Sincerely,

Kevin.

As a point of reference, I use the S12S with the LCD3, and a MAC10T motor. It delivers a maximum of 27 AMPs at 50V, with is enough to go about 32mph on level ground.

My advice would be to use the S12SH, which can provide higher current.

You might get 32 km/h from that little motor. If you want more speed than that, you need a different one. If you had a very light, streamlined road bike, you could get to 45 km/h from it, but you would need to provide all the power below 22km/h to avoid overheating. Fot that, you'd need the 48v version of the S06S.

1. It will work with the KU93, but at 22 amps, it won't survive the first journey. The KU93 doesn't work with the S-LCD3

2. Q-series motors don't work very well sensorless, so you can forget the S09P

3. With the S12S at maybe 28 amps, I don't think you'll get to the end of your street before melt-down..

4. With the S12SH at 35 amps, the gears will strip as soon as you open the throttle.

S12S (12 as in 12 mosfets) controller is too powerfull for small Q85 motor. Even S09S (=9 fets) is too much.

S06S (6 fets) is better choice at 14A peak, 7A cont.
You have to match the controller to the motor, Q85 is about 13A peak.

Edit: d8veh was faster this time

Thankyou,

1. S06SC Sine Wave Controller for Central Motor

2. S06S 250W Torque Simulation Sine Wave Controller
https://bmsbattery.com/ebike-kit/546-s06s-250w-torque-simulation-sine-wave-controller-ebike-kit.html

Which is more appropriate?
Type 1 or Type 2?

I do not know what the differences are between these two?

Someone who can tell me which of these two is the best for my situation?

Thanks.

S06SC (C as in Central motor) is NOT suitable for a hub motor. S06S is the correct controller for Q85 and Q100H motors. If you want speed, better option is to purchuse 48V version of S06S controller sold on aliexpress: http://www.aliexpress.com/item/Regeneration-Electric-Bicycle-Brush-less-Controller-48V-6-MOSFET/1749495210.html

BMSbattery sells only 24V/36V version, and it will turn into smoke machine at 48V system voltage. 328rpm motor is suitable for 24" wheels or smaller. If you have 26" wheel, chance is that your motor will overheat at hills. 201rpm Q100H motor used at 48V system voltage is a better option. Q100H top speed is 25Km/h at 36V and 32km/h at 48V. For faster than that, click on the link "triebfluegel" in my signature.

I have a 28 '' inch wheel (700c)
Is there an overheating protection provided by the controller?
Or has chosen me display the ability to read the temperature of the engine?

What is an acceptable temperature for the engine?

Thank You.

Answered via PM, as I saw it there first.

There's no temperature sensor in the motor, though you could install one yourself and use the white speed sensor wire for the signal.

What is the maximum speed which you can set the S-LCD3 Display?
I read that this standard 25KM / H is adjusted.

What is the maximum speed for this type of display?
Someone who can tell me this?

Thankyou.

On LCD2 it is almost like having a warp speed limit on a car. Not sure if it is 79km/h or 99 km/h, or something like that. Most of us will probably never reach it.

On mine, the upper limit is 72kph.

I think it's 72km/h too. The display can only show a maximum speed too, regardless of whether you go faster.

Yes, it is probably 72km/h.

I have a special case that I am using the Q85 @ 24V hub motor for. Do you know if any of these controllers can do reverse?

The Q85 can't do reverse. Why do you want controller for it that reverses?

Why exactly will this controller now work with a hub motor? Is driving the central motor any different to driving a geared hub motor?
