BLDC Motor Controller 6-72V 15A, Reversible 3-Phase Sensorless PWM Speed Control ESC for Fan Pump

High-performance DC three-phase brushless speed controller with wide input range and clear digital monitoring, designed for aeromodels, water pumps, fans, and other motor-driven devices. Key benefits - Wide input voltage range DC6-72V for compatibility with many battery and supply systems, making it suitable for a variety of power environments. - Supports up to 15A continuous current to handle high-load demands while providing overload protection at 15A. - Built-in digital display shows 0-100 percentage of rotational speed for quick, real-time monitoring and easier debugging. - Bidirectional forward and reverse control with brake and start/stop port for flexible motor direction and stopping options. - Three-phase brushless motor design yields low noise and high efficiency for smoother, quieter operation. Technical specifications - Input voltage: DC6-72V. - Maximum current: 15A continuous with overload protection at 15A. - Display content: 0-100 percentage. - Forward and reverse: bidirectional. - Support load: DC three-phase brushless motor. - With or without Hall: No Hall. - Display opening: L32mm*H21mm. - Wiring type: fence terminal. Control and interface - Speed control mode: potentiometer. - Support external PWM: frequency 1-10K Hz, amplitude 3.3-5V. - Forward and reverse brake start/stop port signal: low potential effective, direct weak signal into the MCU master control. - When using external PWM speed control, disconnect the potentiometer signal line first. - The digital display shows percentage of speed only and does not indicate actual RPM. Installation and safety notes - Connect input with correct polarity; input voltage must equal the rated voltage of the motor and remain within DC6-72V. For example, use 12V
