Discover the Power of ABB Squirrel Cage Induction Motors

ABB, a global leader in power and automation, has been at the forefront of developing cutting-edge ABB squirrel cage induction motors for over a century. These motors offer superior performance, efficiency, and reliability, making them the ideal choice for a wide range of industrial applications.

Basic Concepts of ABB Squirrel Cage Induction Motors

ABB squirrel cage induction motors are AC motors that rely on electromagnetic induction to generate torque. The stator consists of a laminated core with slots containing copper windings, which create a rotating magnetic field when energized. The rotor is made of aluminum or copper bars inserted into axial slots and short-circuited by conducting end rings.

Component	Description
Stator	Creates a rotating magnetic field
Rotor	Converts magnetic energy into mechanical energy
End Rings	Short-circuit the rotor bars
Air Gap	Provides a path for magnetic flux
