ABB's squirrel cage induction motors have revolutionized the industrial landscape, delivering unparalleled efficiency, reliability, and versatility. These motors serve as the workhorses of modern industries, powering a wide range of applications from manufacturing and mining to power generation and water treatment.
ABB squirrel cage induction motors are asynchronous motors that rely on electromagnetic induction to generate torque. The simplicity of their design and rugged construction make them ideal for demanding industrial environments. They feature a stator with a series of coils that create a rotating magnetic field and a rotor with conductive bars embedded in slots. The interaction between the magnetic fields produces an electromotive force (EMF) in the rotor, resulting in current flow and torque generation.
