    Paired motor?

    i remember reading that some controllers need a paired motor to work, this is only for sinewave controllers, but i wasnt too sure what they meant by that, i thought maybe it was the winding pattern? but im really not sure since there was no more information beyond it being "paired" to the...

    Paired motor?

    so i remember reading that, i believe it was sinewave controllers, needs a paired motor to work correctly, my question is: what does paired motor mean? or rather, HOW is it paired? for context, i was rewinding a burnt out geared hub motor with 18 slots and 20 poles, the calculator gave me...

    Hub motor AXLE Cutting and modification

    well no, theres no problem right now as it is, it runs and works just fine, its a joy to ride, more so than i could possibly admit, but in this field when we get that itch to do more or upgrade, it hits hard, so upgrading to atv style independent suspension would naturally push the rear higher...

    XLD Brainpower motor controller XunLiDa

    which ground did you use? i used the ground under k2 and k1, but i haven't noticed any difference in any speed be it low or high, i also try flipping the switch during throttling to see if i would get a slow down or a speed up i also didn't notice anything at all... maybe it needs to be grounded...

    XLD Brainpower motor controller XunLiDa

    so... does anyone know what that 4 pin that connects SD, 5V, GND, and SH does? im reluctant to think its a speed controller/throttle type of thing, but the 5v and sd seems similar to 4.3v and sd, or am i completely wrong about that :shock:

    XLD Brainpower motor controller XunLiDa

    can you clarify just so im not mistaken, you said short all 3 together for low speed? as in connect k1, k2, and ground and for medium speed just leave the pins alone and do nothing, and for high speed, i connect k1 and k2, is that what you meant? cuz reading this thread i understood is vey very...

    XLD Brainpower motor controller XunLiDa

There are 2 extra connectors on my very generic control unit that...
