COMPARISON OF BLDC AND PMSM MOTORS

WebBoth BLDC and PMSM motors have permanent magnets on the rotor but differ in the flux distributions and back-emf profiles. To get the best performance out of the synchronous motor, it is important to identify the type of motor in order to apply the most appropriate type of control as described in the next chapters. Comparison of BLDC and PMSM motors WebPMSM are purposedly wound so the bEMF is sinusoïdal, but I came across BLDC that were sinusoïdal too. As for the drive, you can drive all these motors with trapezoidal drive (6-step) or sinus drive (field oriented control), but you get slightly better efficiency when driving a PMSM with a sine wave (FOC), and a BLDC with 6-step. cracked elbow tipWebMar 6, 2024 · BLDC motors are generally less expensive than PMSM motors.
