SQUIRREL CAGES Meaning and
Definition
-
Squirrel cages, in the context of mechanical systems, refer to a specific type of rotor design commonly found in electric motors or fans. A squirrel cage rotor consists of a cylindrical core made up of laminated steel laminations or bars. These bars are arranged parallel to the rotor's shaft and are shorted at the ends with conductive rings.
The name "squirrel cage" is derived from its resemblance to a spinning exercise wheel commonly used by pet rodents, as it shares a similar structure. This type of rotor design is highly effective at converting electrical energy into mechanical energy, making it widely used in induction motors.
The squirrel cage design encompasses several conducting bars, which act as "squirrel cages" for the rotor's motion. When an electrical current is supplied to the stator, the resulting magnetic field causes the rotor to rotate. As the rotor bars come into contact with the magnetic field, they induce a current that creates an opposing magnetic field, enabling the rotation.
Squirrel cages have numerous advantages, including simplicity, reliability, and low cost. Due to its robust construction, it can withstand substantial mechanical stress, making it suitable for industrial applications. The absence of slip rings, brushes, and external electrical connections ensures minimal maintenance requirements, reducing the risk of failure.
Overall, the squirrel cage design is widely recognized for its efficiency and effectiveness in converting electrical energy to mechanical motion. Its widespread use in motors and fans has made it an essential component in various industries, including manufacturing, transportation, and household appliances.

Etymology of SQUIRREL CAGES
The term "squirrel cage" originated from the resemblance of a particular type of cage wheel to a hamster or squirrel exercise wheel. This wheel is commonly found in squirrel cages, which are cylindrical enclosures used to confine squirrels or other small animals, typically at zoos or research facilities for studying purposes. The word "squirrel" comes from the Old English word "squirvel" or "squeorfa", which refers to a small animal resembling a squirrel. Meanwhile, "cage" traces back to the Old French word "cage" meaning "a cage or prison". Thus, "squirrel cages" describe the specific type of enclosure that resembles a hamster wheel and is used to house squirrels or similar small animals.
