Answer:

The answer is "0.0045 Wb"

Explanation:

Using formula:

\to E_A= \sqrt{2} \pi N_c f \phi\\\\\to \phi = \frac{E_A}{\sqrt{2} \pi N_c f}\\\\                    .......(a)

Calculating the phase voltage of the machine:

V_\phi = \frac{V_L}{\sqrt{3}}

    = \frac{4.16 \times 10^3}{\sqrt{3}}\\\\=2401.7

Substitute the value from equation (a):

\phi= \frac{2401}{\sqrt{2} \times \pi \times  2000 \times 60}

   =4.503 \times 10^{-3}\\\\= 0.0045 \ wb

The rotor flux = 0.0045 Wb

How would you design a wheelchair for wheelchair-using basketball players? Would you make it more or less massive?
emmainna [20.7K]
Less, if it’s too big: hard to control and maneuverability for shooting wouldn’t be that good. a smaller wheelchair allows for faster movement and control, along with easier shooting and upper body movement

Briefly explain how a jet moves
sergejj [24]

Answer:

Jet engines move the airplane forward with a great force that is produced by a tremendous thrust and causes the plane to fly very fast. All jet engines, which are also called gas turbines, work on the same principle. The engine sucks air in at the front with a fan. ... Spinning the turbine causes the compressor to spin.
