KT kunteng Controller Electric Bicycle Hub Motor ebike Controller 36V/48V 250W 36V/48V 500W 1000W Brushless DC Sine Wave sensor Controller
Note:
This is sensor controller, so controller has three big cable and five sensor wires and one speed sensor wire. you motor must have 8pcs wires(None speed signal) or 9pcs wires, If you motor just three big cable,please buy sensorless controller
KT controller can work with geared or gearless motors,aslo work with Brake Rear Light.
XF07, XF08, XF08C motors, KUNTENG BRAND controller set P1=88, one speed measurement signal. Number of magnets=20, gear ratio=1:4.4
P1 = Number of magnets * Reduction ratio 20 * 4.4 = 88
XF15F, XF15R, XF15C motors, KUNTENG BRAND controller set P1=100, one speed measurement signal. Number of magnets=20, gear ratio=1:5
P1 = Number of magnets * Reduction ratio 20 * 5 = 100
