Permanent Magnet Synchronous And Brushless Dc M... -

The primary difference between a and a Brushless DC (BLDC) Motor is the shape of their Back Electromotive Force (Back EMF) waveform .

: Produces a trapezoidal Back EMF, which can result in more "torque ripple" or vibration during commutation. Key Feature Comparison What is the difference between BLDC and PMSM motors? Permanent Magnet Synchronous and Brushless DC M...

: Produces a sinusoidal Back EMF, leading to smoother torque and quieter operation. The primary difference between a and a Brushless
