Abstract Brushless DC motors are known for their versatility and efficiency. Unfortunately the cheap and common method of using trapezoidal current control is not suitable for all applications because of the distracting acoustic noise made during commutation, known as 'ticking'. This paper outlines some methods of controlling the brushless motor to produce much less acoustic noise, including using a DSP for producing commutation period current wave-shaping and a sinusoidal Voltage/Frequency amplitude control.
