The frequency of the current in a squirrel-cage rotor _____ as the rotor approaches synchronous speed.
A) increases
B) stays the same
C) decreases
D) is cut in half
Squirrel-Cage Rotor
A type of rotor in an induction motor, characterized by its cylindrical shape with conductive bars running the length of the cylinder and connected at both ends by conductive rings, creating a cage-like appearance.
Frequency
The number of cycles (of a repeating event) per unit time, measured in hertz (Hz) in the context of waves or electrical signals.
Synchronous Speed
The rotation speed at which the magnetic field in the stator rotates in synchronous machines, typically equal to the AC supply frequency divided by the number of pole pairs.
- Explain the principle of synchronous speed in three-phase motors.
