Question

In squirrel cage motors, skin effect occurs in ?​

Answer 1

Answer:

The nonuniform dispersion of the current density, which passes through these bars, induces skin effect phenomenon. The latter is manifested in high frequency and when the height of the slot is of the order of 20 mm at least [1]. It makes the current flow focus on the periphery of conductor, when the frequency is high

Answer 2

Answer: Squirrel cage is a type of induction motor. It generally occurs in Rotor winding of Squirrel cage motors.

Explanation:

• Induction motors, of which squirrel cage motors are a subtype, are devices that generate motion by exploiting the electromagnetic that exists in the environment.
• These motors are referred to as "squirrel cage" motors due to the fact that the inner component that is attached to the output shaft, known as the rotor, has the appearance of a cage.
• The term "skin effect" refers to the phenomena in which an alternating current flowing through a conductor tends to concentrate more in the areas that are closer to the surface.
• The more time passes, its frequency increases.
• The skin effect causes a rise in the effective resistance with increasing frequency, while simultaneously causing a drop in the effective inductance with increasing frequency.
