Commutator (Six Step)


Category: Controllers

The Commutator (Six Step) block provides six step motor commutation logic signals from Hall sensor input.


Diagram name: Commutator Six Step

Location: Examples > eMotor > BLDC

In this example, Hall sensors measure shaft displacement. Hall sensor output is fed directly to the Commutator (Six Step) block. The output of the Commutator (Six Step) block is scaled to the drive voltage and fed to the motor phases. The voltage level can control speed; however, for large transients, current feedback together with PWM improves control performance.
