1500W มอเตอร์ควบคุมความเร็วจักรยานไฟฟ้า Brushless Dc

Motor Type:Stepper Motor Voltage:48-72V Wattage:1500W Throttle :1.1-4.2V Undervoltage protection :41.5 Positive and negative 0.5V motor phase.Powerful start, climbing power large and small motor noise. When the battery voltage become lower, the current will also become lower to keep normal running.It not only protect the battery and extend the battery life, but also increase the running distance. Automatically recognize the motor phase angle and motor right spin direction.It can be conducted by the Self-Study wires. Start silently, balanced and constant power out-put, Mature Production technical of Controller and authentic quality. Over-heat protection, the controller will cut the power when the temperature is overtop, and restart if the temperature is normal. Intelligent management of battery system, the controller will reasonable control the battery discharge, low-voltage protection function to extend the battery life. When overload of the bike to make the motor stall more than 2 seconds, the controller will cut off the current out-put to protect the motor and battery. Double-e, controller can check the motor hall sensor condition automatically. If the motor sensors are broken, controller will operate to None-Hall e. When the motor phase is failure, controller will protect it, avoid motor burned, and protect the battery at the same time. colour:Sier Material:metal Size:24 * 8.5cm Package Contents: 1* electric bicycle controllerOnly the above package content, other products are not included.
