Homework Statement



Hi there, motor and generator gurus

Suppose a generator has the following specifications, and the rotor turns with frequency 10 Hz. Determine the maximum and minimum value of the voltage generated, using the formula: ε = Βlv

n = 1000 loops = 1000
B = 10 Tesla
I = 10 current of coil in Ampere (A)
A = (0.05 m x 0.1 m) area of coil in m2

τorque = 500 Nm


Homework Equations



ε = Βlv maximum voltage is E0 = NABω Since ω = 2pif


The Attempt at a Solution



My solution is maximum voltage 1000 x 10 x (0.005) x 2 x pi x 10 = 3141 V

Minimum voltage = E0 = 0 (min voltage must be zero)

Assistant needed as my voltage is excessive IMO.

Cheers and thanks

I think I have worked it out, can someone please confirm.

10 Hertz converted to radians is 62.83, therefore my volts would drop to 314 V

and minumum - if e = 0, then the minimum voltage should be 0.

Cheers

Hi there, and help!

I have been attempting to nut this out and could use some guidance.

I think that I have the equation right now E(max) = 2 x n (turns) x B(in tesla)x L x v sin (theta).

Based on the info already available (see previous post) the max voltage is 1000 V.

Can someone please confirm.

Cheers
 
Anyone? Please assist.
