Key Components: Stator: The stationary outer part of the motor. Contains a series of electromagnets (coils) embedded in a metal core. When current flows through the coils, they generate a rotating magnetic field. Rotor: The rotating inner part of the motor. Can be various types: Squirrel-cage rotor: Most common, consists of aluminum or copper bars embedded in a cylindrical core. Wound rotor: Has coils wound on the rotor, allowing for more complex control. How it Works: Magnetic Field Generation: The stator's coils are energized with alternating current (AC). This creates a rotating magnetic field that sweeps around the stator. Rotor Rotation: In an induction motor: The rotating magnetic field induces currents in the rotor bars. These induced currents create their own magnetic field in the rotor. The interaction between the stator's magnetic field and the rotor's magnetic field causes the rotor to spin. In a synchronous motor: The ...

Neutral Shift in Electrical Systems Neutral shift, a phenomenon in electrical and power systems, refers to deviations in the neutral point voltage from its nominal value. This can manifest as voltage differences, neutral inversion, or neutral-point shifts. These deviations can lead to increased voltage stresses on equipment, incorrect operation of protective devices, and premature failures. The document delves into the causes, effects, and mitigation techniques for neutral shift, including the neutral-point shift method used to balance multilevel cascaded inverters. By understanding and addressing neutral shift, engineers can improve system reliability and efficiency.
