Phasing, harmonics, and controls are just a few of the design items that need to be considered early in the design process.

An in-depth look at induction motors with voltage/frequency-controlled VFDs, induction motors with vector-controlled VFDs, and electronically commutated motors.

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.
