CUI's VP of Motion Control, Jeff Smoot, discusses brushless dc motors and how capacitive commutation can speed up the time consuming assembly process. The article was published on Motion Control Tips, a Design World resource.
The article begins, "Capacitive commutation can speed up the assembly of brushless dc motors and be more accurate than conventional Hall sensors...BLDC motors replace brush commutators with sensors and switching electronics that perform the same function. Therein lies a potential problem: It can be time consuming to set up and align the sensors necessary for commutation."
Jeff Smoot then goes into the basics of commutation and concludes with a comparison of sensor-based commutation setups.
