1. The motor starts softer and makes riding more comfortable. 2. Strong climbing power, low motor noise, eliminates tire noise. 3. Can drive sine wave motor, rectangular motor, no for Hall motor. 4. Suitable for electric bicycle, electric scooter. 5. Professional manufacturing, stable performance and high reliability. Condition: 100% new Item Type: Brushless Motor 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 conventional (dual-mode rectangular) controller, function: positive power supply, negative power supply, electric door lock, motor phase line, for Hall line, throttle, three-speed line, low-level brake line, high-level brake line, common instrument line, anti-theft alarm line, anti-theft alarm signal line, reverse line, intelligent identification self-learning line. 1. The shell thickness is increased and heat dissipation is better. 2. Circuit board solution and main program modification. 3. Replace the power transistor. 4. Replace the capacitor. 5. The copper bar is thickened and the inductance accuracy is higher. The controller's uphill speed is increased, the power is enhanced, the speed can be faster, the motor's smoothness is better, and the controller's lifespan is longer. Can support 48V-60V-64V-72V universal. Color: 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 +/- 1-3 cm.
