It is a constant-speed motor, meaning its RPM remains relatively stable across this range.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I control the speed of this brushless motor?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The motor supports PWM (Pulse Width Modulation) signal input for speed control. By adjusting the duty cycle of the PWM signal, you can reduce the motor speed down to approximately 1000 RPM while still maintaining strong torque output.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does the BL3525O motor come with a driver board?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, this motor includes its own integrated driver board. It can run directly from a single DC power supply without requiring an external motor driver, making it convenient for DIY and prototyping applications.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What happens if I connect the motor wires in reverse?\u003c\/h4\u003e\n\u003cp\u003eA: Reversing the polarity (connecting red to negative and black to positive) is strictly prohibited and may permanently damage the driver board. Always connect the red wire to the positive pole and the black wire to the negative pole.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
