WebTo finish, in the particular case of BLDC machines, i.e. PMSMs with trapezoidal back- EMFs supplied with square-wave currents, most of studies focused on their acoustic noise reduction is achieved through reducing its torque ripple, mainly due to phase commutations (Salah et al., 2011), or by increasing the conduction time of the switches ... 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.

WebMar 6, 2024 · BLDC motors are generally less expensive than PMSM motors. This is because BLDC motors use electromagnets instead of permanent magnets, which are …
WebWhat are BLDC/PMSM and FOC? BLDC/PMSM is a brushless motor that uses the force generated by the inconsistent magnetic fields of the stator and rotor to drive the motor. The rotor of this motor is a permanent magnet, and the stator is composed of multiple electromagnetic coils. Figure 1. Consistent Magnetic Field Figure 2. Inconsistent … WebApr 25, 2024 · Due to low torque repulsion, PMSM got higher and smooth torque with higher efficiency and low noise compared to BLDCM. PMSM has a higher power density, which will help in reducing the size of the motor. …
WebJul 26, 2007 · Here’s how Dr. Aengus Murray of International Rectifier, explains the difference: “A PMSM is designed to have a sinusoidal back EMF, so the rotor is shaped …
