2.1 Optimizing acoustics with sensorless field-oriented control motor driver (MCF8316A)

Acoustics performance with MCF8316A can be optimized by configuring PWM modulation schemes and enabling dead time compensation. In this application note, we used an air purifier motor to optimize acoustics performance with MCF8316A.
