Feature: 1. Wide Applications: Brushless motor speed controller is suitable for electric motorcycle electric scooter brushless dc driver. 2. Effective Control: Brushless motor controller can effectively control the motor, after replacing it with our controller, it can obviously enhance the speed of the motor and effectively increase the power of the motor. 3. Stable Performance: Sine wave controller with stable effect is not easy to fluctuate, and can be well matched with QS hub motor or QS mid drive motor. 4. Heat Resistant: Brushless DC motor controller protects the battery and extends the battery life, and also increases the driving distance. It is high temperature resistant and can be used stably for a long time. 5. Transparent Case: Brushless DC motor controller is designed with a transparent case to make your vehicle look cooler and stand out from the crowd. Specification: Item Type: Brushless DC Motor Controller Material: ABS Model: ND72280 Voltage: 72v Phase Wire Current: 280A Busbar Current: 80A Waterproof Grade: IP67 Number of Tubes: 12Sensor Type: For Hall sensor Applicable Motor Power: Equal to or less than 2000W (this value is the normal matching value, if you do not pursue the torsion and extreme speed, you can float up a power band)Fitment:For electric motorcycle electric scooter brushless dc driver. Package List: 1 x Controller 2 x Wire Speeds 7 x Screws Note: The controller is a sine wave type controller, which is a brushless DC controller with self learning function. Generally, it matches well with QS motors, if you want to match with new brand motors, some parameters need to be tested by yourself.
