V/Hz Control for Motor Drives (Full Lecture)

In this lesson we'll take a brief look at V/Hz control for motor drives. We'll define base and maximum frequency. We'll learn motor drives not only vary excitation frequency but also applied voltage for excitation frequencies below the base frequency. Additionally, we'll examine simple linear V/Hz profiles and more advanced quadratic V/Hz profiles, dual slope V/Hz profiles, and special purpose V/Hz profiles for reduced or increased torque applications. Finally, we'll preview how the V/Hz profile must be used in combination with frequency as function of time plot during acceleration and deceleration events. (Full Lecture) NOTE: Alternative V/Hz profiles include "constant boost" which is similar to a linear profile, however, includes a initial starting bias at low frequencies it is then linear to the base frequency. Additionally, a "start boost" profile includes a constant boost at low frequencies then it flat lines until it meets the normal V/Hz profile. Other application specific profiles exist. ___________________ If you wish to support this project please visit the Patreon page at:   / bigbadtech   ___________________ Copyright information: Use this lecture.
