## Acoustics

Physics, Acoustic

Fundamental Attributes $$c = \lambda f$$ $$f = \frac{1}{T}$$ $$\omega = 2 \pi f$$ $$k = \frac{2 \pi}{ \lambda}$$ Where $$c$$ is the speed of sound in the medium, $$\lambda$$ is

## Induction Machines

Electronics, Physics

An induction motor consists of an external stator and an internal rotor. Windings embedded in the stator is excited by a 3-phase AC supply to produce a rotating magnetic field.
