Usage Tips:1.motor starts more smoothly and makes riding more comfortable. 2.Strong climbing power, low motor running noise, eliminating tire noise. 3.Can drive sinusoid motor, rectangula motor, no for Hall motor. 4.Suitable for electric, electric scooter. 5.Professional manufacturing, stable performance and high reliability. Condition: Item type: Motor Brushless Controller Voltage: 48V 60V 64V 72V (the above voltage can be applied at the same time) Power: 1000W-1500W Current limit: 26A-32A 12-tube convention (dual-mode rectangula) controller, function: positive power supply, negative power supply, electric door lock, motor phase line, for Hall line, accelerator throttle grip line, three-speed line, low-level brake line, high Level brake line, ordinary instrument line, anti-theft alarm power line, anti-theft alarm signal line, reversing line, intelligent identification self-learning line. 1.The thickness of the shell is increased, and the heat dissipation is better. 2.Circuit board solution and main program replacement. 3.Replace the power tube. 4.Replace the capacitor. 5.The copper bar is thickened and the inductance accuracy is higher. The uphill torques of the controller is increased, the power is strengthened, the speed can be faster, the smoothness of motor is better, and the life of the controller is longer. Can support 48V-60V-64V-72V universal. Colour:silver Material:aluminum alloy Package Contents: 1x brushless motor speed controller Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.The measurement allowed error is +/- 1-3cm.
