I have an 18V brushless DC motor for which I ordered a ZS-X11H motor controller. The motor is reclaimed from a robot lawn mower, and I do not know what the 8-wire pinout is. The mower PCB ICs have been black-topped and sealed in clear resin, so no clues there.
Careful examination of the cables reveals that three of the eight wires are 20AWG, with the remaining five being 22AWG. I am assuming that the red and black wires are +5V and ground, leaving three 20AWG wires for the motor phases and the rest for the Hall sensors. Yes, it is a big assumption, but that is all I have right now.
Given this wafer-thin (suspect) information, how would you suggest I ascertain the correct phase and Hall sensor order please?
Many thanks for trying to help, but my wire colours are different, so I think I may have to remove the motor casing to see if there is a PCB with an ident layer. Just for the record, and in the faint hope that someone recognises this, here is what I have:
Husqvarna Motor
5996208-01A
1998-1E70010-18VDC
310512J1000632
Black - 22 AWG
Blue - 20 AWG
White - 20 AWG
Yellow - 20 AWG
Red - 22 AWG
Green - 22 AWG
Purple - 22 AWG
Grey - 22 AWG
I'm reluctant to remove the motor casing to avoid accidental damage to the motor. But having found this YouTube video on connecting an unknown BLDC motor, I think I shall attempt this route. However, unlike the video creator, I shall halve the rated voltage and limit the current via my bench PSU to eliminate any 'magic smoke'.
I am using the ZS-X11H Version 2 Brushless DC motor driver, which supports Hall-effect feedback. Not modified in any way. The wiring colours are as follows:
Black -> Ground
White - A Phase
Blue -> B Phase
Yellow -> C Phase
Red -> +5 Voltsd
Green -> Hall A Phase
Purple -> Hall B Phase
Grey -> Hall C Phase
The motors have the markings:
5996208-01A
1998-1E70010-18VDC
310512J 1000632
For the cutter motor, swap White and Blue. Hope that helps.
