36V Brushless controller on ebay

[allotmenteer]

Hello all

I've just bought one of these on ebay:

Item # 300166787182

It seems to be the same as my existing controller so it'll be great to have a backup. Only £20 as well!

There are other ebike parts available if anyone is interested.

Which Controller

They look great and at a good price, I have a Ezee sprint if I added 10 more cells to make a 48volts battery whould this Controller be the right one two go four
Rated Voltage: 48 Volts
　 Rated Power: 350 watts
Under Voltage Protection: 42 Volts
　 　 Maximum Current: 18 Amps
Usable Motor: 350 Watts 3 phase
brushless motor.

It may well work and for only £20 you can't go wrong. 48V might be a bit scary though. I get 24mph on the flat at 36V with gentle pedaling, at 48V I might get 32mph. The controller looks to have a speed control pot (blue wire) which you can turn to adjust the speed of the wheel. I think it's for setting the speed for various wheel sizes but if you are running at 48V you may want to set it to limit yourself to a sensible max speed.

I'll post more details of the controller when it arrives. Last thing I got from HK came in about 10 days.

Nice find allotmenteer, just bought one, I am sensible with the speed on bikes I also ride a vfr750 (Honda) that will go 143mph but I don’t go that fast all the time . I`m looking for more distance than speed 48volt*8amp=384wh If it dose have a pot I will be able to keep it legal.

We all have our problems in life

That does sound a good find, even for a newbie like me, I can see me pottering one day and upping the Voltage is the obvious way to get more.
However, what about the risk to ones licence should some over zealous cop take an interest one day? Is it worth the risk I ask myself.

Great, I hope it fits your needs. I didn't find it though, I saw it on endless sphere:

The controller from EBay tuned up today , having a few problems wiring it up , on the early ezee sprint there are three wires in a connecter White yellow and blue coming from the handle bars they connect to the ezee controller red black and yellow, are these for the throttle and battery LED? If so which one is from the LED, the other two wires coming from the same harness on the handle bars are red and green I take it these are for the brake? If any one knows can they help?
Thanks.

3 wires doesn't sound enough Andy, both my Sprint and Torq have 6 wires from the handlebars, I would guess their functions are :-

common ground, 5V for throttle sensor, throttle sensor return, battery voltage for meter, brake cutout, pedelec mode switch.

I don't know which colour does what though.

In addition there are the three motor phase wires and the 8 motor sensor wires.

Hello Andy

I'll have a look (and test) my one tonight. I've been busy over the last few days so I haven't put it on the bike yet. It looks exactly the same as my existing one so I don't expect any problems. I'll post the results later.

wires.

There are 5 wires in two blocks, my sprint is throttle only, no pedelec

In addition there are the three motor phase wires and the 8 motor sensor wires.

Yes I have those connected already. but only 5 sensor wires!

 

[flecc]

A sort of typo I think. Eight wires in all including the three phase wires.

Yes that’s what I thought, still cant work out which wire is which (white, red, yellow, green, blue) on the new controller red, green, yellow are throttle,
And black, red, yellow, brake.
I am fairly shore the green is the throttle and thought the red will be live,when I connect them up the wheel kicks when I apply the brake?

 

[flecc]

My guess is no better than yours here, the colour codes vary so often. If the motor hums continuously as well as kicks when the brake connection is applied, it could be the three phase wires aren't correctly connected, since if they aren't, that's what happens,

You could try the three phase wires in the possible configurations first in that case and see if the wheel runs when the brake connection is made. With that established, you could then then sort the brake/throttle connections.

Cheers I think I will give it a brake, I have been at this sense yesterday morning my heads spinning with all the possible color combinations , I will let allotmenteer have a go tonight with his controller maybe he will have better luck, thank god I have the Lafree to full back on . I am in no rush just inpatient .

Hello Andy

Unfortunately it's lashing outside so I'm not venturing out to the shed to get the bike but I've looked at my controller and the notes and pictures I've taken previously. I think they work as follows

First the ones you know about:

2 thick battery wires (red, black)
3 thick motor phase wires (yellow, green, blue)
5 hall effect sensor wires (thin ones wired to a block) (red, yellow, blue, green , black)

2 blue wires going to a potentiometer (this one controls the maximum wheel speed)

2 sets of yellow, black, red thin wires going to a connector. - I don't know what these are as I don't use them on my bike. As you say they are probably brake cutoffs.

1 set of green, yellow, red going to a connector. As you state this one is for the throttle. The yellow is -ve (goes to the -ve on the pcb inside the controller box), the red is +ve and the green is the speed one (on my existing controller this goes to a spot marked sp on the pcb.

1 single thin blue ending in a bullet connector. This is anybody's guess as I don't use it. The ebay page said speed controller so this could be the pedelec sensor?

I hope this helps.

When the rain stops I will get out to my bike to have a look. It may be the weekend before I get to fit the new controller as I've got very little free time to do it this week. If / when I find out more I'll post details.

[aaannndddyyy]

Cheers I put the ezee controller back on to make shore I had not done any damage to the rest of the electrics on the Sprint every thing still works ok .

It’s the five wires coming from the handle bars White yellow blue red and green

Where I think the problem is coming from unless as flecc saids

it could be the three phase wires aren't correctly connected
.

 

[allotmenteer]

Ah so it seems the problem is not so much with the new controller connections as with not knowing what the ezee ones are. Can you open up the ezee controller? It may be that you can see where the wires go to and there may be some markings on the pcb to identify the connections.

 

[aaannndddyyy]

Finally a brake though with my Ezee sprint and 48v EBay controller, after 8 weeks and many headaches , I have finally worked out a wiring combination that seems two work, for anybody interested it goes like this the 3 main hull wires are controller yellow to blue, blue to yellow, green to green. The five thin hull wires, yellow to blue, green to green and blue , yellow left blank, red to red black to black. With 43 nimh batteries fully charged on a quick test ride gives 27 mph on the flat derestricted .

Well done Andy, persistence paid off in the end. I'll keep a copy of a link to your post since this could crop up again.
