Function: 1. The drive motor starts more smoothly and makes driving more comfortable. 2. Strong climbing power, low motor noise, eliminate tire noise. 3. Can drive sine wave motor, square motor, not for Hall motor. 4. Suitable for electric bike, electric scooter. 5. Professional production, stable performance and high reliability. Item Type: Brushless Motor Controller Material: metal Size: Approx. 17.7 x 8.4 x 4.3 cm / 7 x 3.3 x 1.7 inch Weight: Approx. 560g Voltage: 48V 60V 64V 72V (the above voltage can be applied at the same time) Power: 1000W-1500W Current limit: 26A-32A 12-pipe conventional controller (dual mode rectangular), function: positive feed, negative feed, electric lock, motor phase line, for Hall line, throttle line, three speed shift line, low level brake line, high level brake line, ordinary instrument line , anti-theft alarm power line, anti-theft alarm signal line, reverse line, intelligent identification self-learning line. 1. The thickness of the shell is increased and the heat dissipation is better. 2. Solution of the PCB and replacement of the main program. 3. Replace the feed tube. 4. Replace the capacitor. 5. The copper rod is thickened and the accuracy of the inductance is higher. The driver torque uphill, the power is strengthened, the speed can be faster, the drive motor running smoother, and the driver life is longer. Can support universal 48V-60V-64V-72V. Package List: 1 x motor controller
