1. ELECTRONIC DIFFERENTIALWheelchair joystick controller relies on advanced driving algorithms and intelligent control, with flexible operation, strong controllability, 'Scurve' acceleration and deceleration, and instant soft start, allowing the electric wheelchair to drive comfortably and ly under any road conditions experience. 2. BRUSHLESS MOTORClosedloop control of speed of brushless motor without induction. When braking uphill, the electromagnetic brake when the motor speed is 0 can be detected, and it will not slide backwards, preventing the wheelchair from turning backwards. 3. FUNCTIONJoystick wheelchair has overcurrent, overvoltage, overload, overheat, undervoltage and other protection functions to ensure that the electric wheelchair is more reliable and r. 4. AUTOMATIC IDENTIFICATIONElectric wheelchair joystick controller replacement can automatically identify whether the motor connector and the electromagnetic brake connector are connected correctly, and can distinguish the reverse and wrong connection of the two.
