What is the purpose of a squirrel cage?

Squirrel cages are found in HVAC systems. Their purpose is to provide the system with a blower fan. For a person with a heating system that has forced air, the squirrel cage motor is what rotates the fan. This fan rotation will blow both the cool and warm air through the ventilation system.

This can be found in systems such as an air conditioner or a furnace. Squirrel cages can also be found in AC and it can also go by the name of squirrel cage rotors. The rotor will contain a steel cylinder and it will include a conductor that is made of aluminum or copper.

The purpose of a squirrel cage motor in a home HVAC system is that it provides a blower fan. Suppose you have a forced-air heating system, such as a furnace or air conditioning system. In that case, the squirrel cage motor is the part that rotates the fans that blow the warmed and cooled air through the ventilation system.

The squirrel cage can also relate to a type of AC (alternating current), induction, motor, as it is sometimes called a squirrel cage rotor. A squirrel-cage rotor is the rotating component of the common squirrel cage induction motor. It contains a cylinder of steel laminations, with an aluminum or copper conductor embedded in its surface. In operation, the non-rotating stator winding is attached to the alternating current in the stator produces a rotating magnetic field.
