Understanding Net Field, Rotor Field and Stator Field — Lesson 6

This lesson covers the fundamental concepts of electrical machine operations, focusing on the stator and rotor parts of the machine. It explains how these parts carry current and produce their respective fields, resulting in a resultant field. The lesson further elaborates on how to calculate the induced voltage in the coils by considering the resultant voltage. It also discusses the operation of induction motors and the polarity of the induced voltage in the stator and rotor conductors. The lesson concludes with an explanation of the motor and generator modes of operation and how the direction of the fields can be properly drawn in any machine.

Key Takeaways

- In any electrical machine, there are stator and rotor parts that carry current and produce their respective fields.
- The induced voltage in the coils can be calculated by considering the resultant voltage instead of calculating the voltage induced in the stator coil.
- In induction motors, the polarity of the induced voltage in the stator and rotor conductors can be determined.
- Electrical machines can operate in motor and generator modes, and the direction of the fields can be properly drawn in any machine.
