Intelligent brushless sine wave controller for electric bike/electric scooter/brushless motor if motor not have hall wire, not connect hall wires also can work voltage: 36V/42V/48V/52V/60V/72V/84V universal current: 20A-25A Phase angle: 60 /120 all can be used rated power: 350W-500W-600W all can work 1.PAS(pedal assist) 2.intelligent recognition?self-learnig line ) 3.low level brake 4.reverse gear 5.cruise 6.speed controller handle?throttle) 7.multiple data meter 8.hall meter 9.hall wires 10.three speed gear 11.phase meter 12.electric door lock 13.anti-theft alarm signal 14.anti-theft alarm power 15.high level brake 16.special for differential motor 17.phase line 18.battery how to connect ? 1.connect the motor line (color to color) 2. connect the battery line(red wire :battery + , black:battery-) 3. connect the controller throttle line?color to color) , connect electric door lock ?if your throttle not have electric door lock, controller electric door lock can be shorted) 4. connect the hall line(if motor without hall line, don't need connect) 5.docking the two self-learning lines, the wheel will forward or reverse. (1.if wheel forward ,Separate the self-learning line. 2.if wheel reverse, Separate the self-learning line. Docking the self-learning line again, if wheel forward ,Separate the self-learning line.) 6.other functions can be connected as needed.
