I am building a scooter from scratch using this motor. I have no experience with brushless and I am hoping I might get some help here. I have no interest in changing the rotation, but I have been unable to find a wiring diagram so I can figure out what the heck to hook up. I work about 2.5 miles from work and I am hoping I can get this thing to take me to and from work. I weigh about 275 lbs and I am not worried about speed, so I will be gearing it deep so I can pull hills and such. I am no electrical engineer, so if the diagram is labeled in all sorts of mumbo jumbo, please translate. I know I need pot throttle, but I don't know how to hook it up. Any help would be great. What kind of batteries do you all recommend. I have a couple of optima yellow tops from my 4x4 winch setup I was planning to use. Will these work? Sorry for the ?'s and sounding so helpless, bu tI really want to get this up an running soon.

Deafscooter, I checked the thread you mentioned but I did not see the answer to my question. Could you clarify. What I really need is a diagram explicity spelling out what the various wires in this motor are for.
Meatball,
Does your motor have the built-in controller?
I can't find a diagram of that either, but for the internally controlled ones, there are two fat wires, one black (negative), one red(positive), that go to the battery. 24v only. Two Optimas would be fine.
There's a 3 pin connector that goes to the throttle, and a two pin connector that goes to an optional brake cutout switch. You don't have to connect the brake switch to make the motor run.
I don't remember the colors on the throttle connector. If you can see what colors the wires going to the 3 pin connector are, I can probably figure it out.
As I recall, it will only work with a resistor pot type throttle, not a hall effect throttle.
Those motors had a bad habbit of blowing the internal controller. To minimize the possiblility of this, I'd recommend gearing it for a fairly slow top speed. If the internal controller blows, it's possible to take it apart and bring the wires out to an external controller. The external controller cost more than the whole motor, so that sucks. The external controller does allow higher voltage and power.
This motor is the one with the built in controller_
ok, so the 3 wires going to the connector are red, dark blue, and white. There is also a smaller, 2-pin connector that has a green and a brown wire going to it. Should I just use a ready made throttle or can I fab one up myself. I am trying to do this as cheaply as possible. Does anyone know what kind of rpm's I can expect out of this motor at 24v. Also what kind of power? It would help me determine gearing. I am sure there is a calculation for the theoretical, but I haven't had any electronics class in a while
As I recall the motor runs around 3,000 rpm. Output is rated for 400w, but could be a bit higher for short bursts. Specs indicate 30 amp maximum draw @ 24v.
Ready made throttles like a Magura are pretty expensive, but well made. You might find a cheap chinese one at TNC scooters. You could fab one from a regular pot, a spring, and an old motorcycle throttle that pulls a cable.
With a pot throttle, there's not much risk in getting the wires mixed up other than the motor might run when you don't expect it to. Do initial testing with the wheel off the ground or the chain off. Just SWAGing: red= high side, dark blue= low side, white= signal. This is a total guess, but there are only six possible combinations, so you can swap wires around until it works.
The two pin connector can be left empty. If you short the two pins with your brake switch, the motor stops.
Thank you so much for your help! I should have this beast running by the weekend!.
Hi
Red Low white high, wiper blue, this is for a 300 watts motor, which very possibly should be the same as 400 watts.
