36V 48V 60V 64V 72V 35A 40A 1000W 1500W Square Wave Brushless Controller for Electric Bike E-Scooter

["This controller supports a wide voltage range of 36V to 84V, with a current limit of 40A and a rated power coverage of 1000W-1500W. It is widely adaptable and can be matched with different configurations without the need to replace the controller. High power output provides strong torque and acceleration performance during starting, climbing, and loading, meeting daily commuting needs.","Adopting a mature and reliable square wave (trapezoidal wave) control scheme, the control algorithm is simple and direct, and the hardware cost is more advantageous. At the same time, it can achieve higher motor speed and crisp power response. Compared to the much more expensive sine wave controller, this blue square wave controller provides a better choice for users who pursue pure power and ultimate cost-effectiveness.","Built in comprehensive protection system, supporting overvoltage protection, undervoltage protection, overcurrent protection, overheating protection, and locked rotor protection. Undervoltage protection can prevent excessive discharge of the battery and extend its lifespan; Overcurrent and overheating protection actively limit the current under extreme working conditions, avoiding damage to the MOS transistor and ensuring long-term stable operation of the controller and motor.","When the controller is working, the power MOSFET generates heat. This product adopts an aluminum alloy shell and optimized heat dissipation structure, which can quickly conduct and dissipate internal heat, effectively preventing high temperature from triggering thermal throttling and causing power decline. The sturdy aluminum alloy body provides excellent impact resistance and protection, without fear of bumps and vibrations during daily cycling.","The controller is equipped with universal standard interfaces and line sequence identification, supporting automatic recognition of 60 °/120 ° motor phase angle, providing rich extended functions such as low-level/high-level braking, cruise control, three speed transmission, reverse, Hall/phase instrument, anti-theft alarm signal, etc. When the Hall sensor fails, it can still continue to operate without Hall mode, ensuring uninterrupted riding to the maximum extent possible."]
