The function of ABB AC motors is to convert electrical energy into mechanical energy. Specifically, it utilizes the principle of electromagnetic induction to apply the torque generated by the electromagnetic field to the rotor, causing it to rotate, thereby achieving the conversion of electrical energy to mechanical energy. ABB AC motors consist of two parts: stator and rotor. The stator consists of a base, iron core, winding, and casing. After the winding is energized, a rotating magnetic field is generated. The rotor is composed of an iron core, winding, and bearings. The induction in the rotor winding generates current, which interacts with the rotating magnetic field to generate electromagnetic torque, driving the rotor to rotate. ABB AC motors have a wide range of applications, including: Fan and pump: ABB AC motors are used to drive fans and pumps, conveying gases and liquids. Conveyors and drum
