PMSM et BLDC

PFC circuit & Components_edited.png

PFC Circuit & Components in Lumsyn 1500W series BLDC Motor Controller/driver

BLDC Driver without PFC:
  • Simpler design with fewer components.

  • Lower cost.

  • Drawbacks:

    • Lower power factor (draws more current than necessary).

    • Contributes to harmonic distortion on the power line (can potentially affect other devices).

    • May be less efficient overall.

Choosing Between Them:

  • Applications with strict regulations on power factor or harmonic distortion (e.g., industrial settings) will likely require PFC.

  • For cost-sensitive applications where power quality is less critical, a driver without PFC might be sufficient.

  • Consider the overall power consumption of the BLDC motor. For high-power applications, the efficiency gains from PFC can be significant.

Here's a table summarizing the key differences:

Comment fonctionnent les moteurs PMSM et BLDC ?

1. Moteur à courant continu sans balais

Un moteur à courant continu sans balais est une version améliorée d'un moteur à courant continu à balais. L'absence de balais donne aux moteurs BLDC la capacité de tourner à grande vitesse et avec une efficacité accrue.
