A 3-phase, 16-pole synchronous machine is driven by a prime mover at a speed of 600-rpm with the stator open circuited. The rotor flux per pole is 0.025-Wb. Determine
(a) the frequency and rms value of the induced voltage in the stator per phase having 450 effective turns;
(b) line voltage for the Y-connected machine.
Solution:
(a) The frequency of the stator voltage is from (1.1): f = pn/60 = 8.600/60 = 80-Hz.
The voltage generated per phase is using (1.4):
Eφ = 4.44 .80.450.0.025 = 3996 - V ≈ 4 - kV.
(b) The voltage across the stator terminals (line-to-line) is VLL = √3. 3996 = 6921.3 -V.
Q. Explain Current and Magnetic Force? The rate ofmovement of net positive charge per unit of time through a cross section of a conductor is known as current, i(t) = dq / dt
Q. What is meant by amplification? The basic amplifying elements are, namely valves (vacuum tubes), bipolar transistors and FETs. The term "amplify" basically means to make str
