Kamanda Steel Plant Interview Questions, Process, and Tips

Motors convert electrical energy into mechanical energy, while transformers transfer electrical energy between circuits at different voltages.

• Electric motors operate on the principle of electromagnetism, converting electrical energy into rotational motion.

• Transformers consist of two coils of wire (primary and secondary) wrapped around a magnetic core, enabling voltage transformation.

• An example of a motor is an electric...read more

Star-delta connections reduce starting current and torque in three-phase motors, improving efficiency during startup.

• Star Connection: All three phases are connected to a common point, reducing voltage across each phase.

• Delta Connection: Each phase is connected end-to-end, allowing full line voltage across each phase.

• Starting Current: Star connection reduces starting current to about 1/3 of delta connection, minimizing ...read more
