Speed Control Basics: VFD or Triac for AC Induction Motors?

When a voltage is applied to an AC induction motor, it runs at a certain speed.  Variable speed requirements for AC induction motors are typically fulfilled by a 3-phase motor and an inverter or VFD.  This blog post also introduces another option.
