Electric Brushless DC Motor for Razor Upgrade Kits 48V 2000W BLDC Motor with Bracket Rated Power: 2000W Rated Current: 42A Rated Speed: 4300RPM Toque: 6.9N.M Phase Shift Angle: 90-110(You can set it to 100) 72V 3000W Brushless DC Motor with Bracket Rated Power: 3000W Rated Current: 45A Rated Speed: 4900RPM Toque: 5.4N.M 45A Fardriver Controller Motor Direction: By change the number(0 or 1), the motor can rotate CW or CWW Throttle Acc Step: Speed fast, 8~224, the larger the number,the faster the throttle. For electric motorcycle,many users preferto respond quickly, so the set at 64,128. Throttle Low: Setting the low throttle threshold is generally 0.2-0.3V higher than the idle voltage, to ensure that the motor works in the idlestate when stopping. Sine Wave Controller FarDriver controller is sine wave type controller, which is brushless DC controller with self-learning function The 48V 2000W Brushless controller is equipped with a buzzer. when an alarm is triggered, the buzzer will emit corresponding alert sounds, Different buzzer counts represent different error codes. How to Get the Instructions Throttle High: Keep the set value below full voltage, but not too low. To automatically detect whether the throttle is damaged, we setan alarm limit 0.6V above the high throttle threshold. if the rotor is damaged, the controller cuts power output to preventaccidents. Size of the Fardrive Controller Small size, high efficiency, low temperature rise, small running current With self-learning function, excellent commonality, with flux weakening function.(The product does not contain magnetism) It suit for electric Motorcycle Motor and other type Motors. Wide Application The 2000W E-Motor is Good for Electric Scooter, Mini Motorcycle, Dirt bike, Electric Go karts, Razor, Quad car，Other DIY project and more. Why does the motor not work and have no response? Please check whether the electric lock wire connection is correct and the voltage is normal. Since both the controller and the motor are high power, so the requirements for discharge are also high, please make sure your 48V is fully charged. Why does the motor not work and have no response?
