What is a Squirrel Cage Motor and How Does it Work?

Some of the most common types of squirrel cage motor use three phases, meaning the input current is three identical AC frequencies, split by 120 degrees of phase. Three-phase motors are self-starting, meaning the only necessary input is a starting voltage, and makes these motors essentially plug-and-play.
