Question

Using the experimentally determined resonant frequency and measured value of the capacitor, find the value of the inductor. 4. does the resistance change the resonant frequency?

Answer 1

2.496 HZ is the resistance change the resonant frequency.

Given, Supply frequency, f = 60 12

number of poles, P = 4

Full load speed, Ne= 1725 rpm

Synchronous speed; No= 1201= 120X60 = 1800 rpm

P

4

We know the formula for Full load-speed

Ne = N's (1 - Sf)

where se = full load rotor ship

Ne = 1 - SP

SQ = 1- Ne = 1- 1725 = 0.0416 DY 4-16%

1800

SQ= 4. 16 % or 0.0416

Frequency of rotor, fy= Sgif = (0.0416) ( 60 ) = 2.496 Hz

fr = 2.496 HZ
