The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

1. Field-oriented control (FOC), also known as vector control, maintains a constant stator field in quadrature with the rotor field irrespective of any bandwidth limitations presented by the PI ...

This application note discusses the Field Oriented Control (FOC) of 3-phase AC induction motors. Field Oriented Control is also referred to as Space Vector Control. Vector control provides efficient ...

Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...

In a speed controller, the motor’s speed (or velocity) is being controlled. There is an element that detects speed, whether it be a tachometer or some sort of encoder. This monitoring element provides ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...
