Q: How to reduce BLDC motor noise?
A: To reduce noise in a BLDC motor, it's important to optimize the motor control strategy and address the root causes of acoustic emissions. Using Field-Oriented Control (FOC) and smooth PWM control, such as sinusoidal or space vector modulation, helps minimize torque ripple and ensures smoother motor operation, thereby reducing noise. Additionally, lowering the switching frequency of the inverter can reduce high-frequency noise, although this may affect performance in some cases. Implementing proper motor design, including selecting high-quality bearings and minimizing mechanical vibrations, also plays a crucial role in minimizing noise. Lastly, ensuring that the motor runs within its optimal operating range can reduce unnecessary stress and prevent excessive noise generation.
