FAQ
Q1:Does this BLDC motor controller PCBA support real-time speed monitoring for smart devices?
A: Yes. The board features an integrated FG speed feedback signal that outputs 3 pulses per revolution. This allows your device's main MCU to accurately monitor the motor speed in real-time, which is essential for maintaining consistent performance in professional percussion massage guns and high-end beauty tools.
Q2: How does the 20kHz PWM frequency benefit high-speed beauty instruments?
A: The 20kHz drive frequency is the core of our silent drive solution for beauty devices. By operating at an ultrasonic frequency, it eliminates the high-pitched electromagnetic "whine" typical of brushless motors. This ensures a premium, whisper-quiet user experience for high-speed brushless hair dryers and facial care tools.
Q3: Can the BL36 driver board handle motor stalls or overheating during intensive use?
A: Absolutely. Safety is built into our PCBA design. The board is equipped with 4.0A overload protection to prevent circuit failure during motor stalls and a 110°C thermal cutoff to protect both the brushless DC motor driver and the device housing from overheating, ensuring long-term reliability for handheld beauty equipment.
