Hi guys I have a Conhismotor ebike 48v 1000w (http://bit.ly/1UIkvjD) and bought a replacement controller (http://bit.ly/1UIoUTw) from same company when the carrier collapsed with 2 motor wires shorting.
Unfortunately the wheel now only judders or spins very briefly so fearing motor damage bought a tester as shown here on the site https://endless-sphere.com/forums/viewtopic.php?f=31&t=20413.
The sequence of motor hall sensors test correctly 100.110,010,011,001,101 when the green and blue hall wires are reversed as they were originally.
The winding of motor test shows the 3 led's flashing in sequence from right to left (?).
The controller output test shows adjacent lights revolving clockwise when the colours are paired as they were originally. The video on the tester page however shows opposing led's flashing and can make this by swapping phase wires but the motor will not run with any of the 6 possible connections.
I wrote to Conhismotor and received reply "From your description, this is 99% because of hall sensor, maybe be burned or angel is not very correct, so the best way is change hall sensor". I assumed an 'angel' might be a sensor askew so opened the hub and found one of the sensors was a tiny bit out and not glued down, effected a repair with epoxy resin.
Unfortunately no change, settings on LCD panel are correct, the insides of the old and new controller look the same. I don't know what else to try and hope a contributor can advise.
