Once the control method of choice only in high-performance industrial ac-servo drives, FOC (field-oriented control) is finding its way into lower end industrial and many appliance applications with ...

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 ...

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 ...
