squirrel cage induction
The squirrel cage induction motor stands as one of the most widely used electric motors in industrial applications, characterized by its robust and straightforward design. At its core, the motor consists of a stationary outer stator and a rotating inner rotor that resembles a squirrel cage, hence its name. The stator contains wound coils that create a rotating magnetic field when energized with alternating current. The rotor features conducting bars, typically made of aluminum or copper, connected by end rings, forming a structure similar to a hamster wheel. When the stator's rotating magnetic field interacts with the rotor, it induces electrical currents in the conducting bars, creating magnetic fields that cause the rotor to follow the stator's rotating field, thus producing mechanical rotation. This motor type excels in various applications due to its self-starting capability, minimal maintenance requirements, and ability to operate under varying load conditions. The absence of brushes or commutators significantly reduces wear and tear, making it particularly suitable for continuous operation in industrial settings, from conveyor systems to pumps and fans.
