Ω and the reactance is 20 Ω. Calculate the slip at this speed.
The synchronous speed (Ns) of a 6-pole motor operating at 50 Hz can be calculated using the formula:
Ns = (120 * f) / P
Where:
Ns = synchronous speed in RPM
f = frequency in Hz
P = number of poles
Plugging in the values, we get:
Ns = (120 * 50) / 6
Ns = 1000 RPM
The slip (S) can be calculated using the formula:
S = (Ns - N) / Ns
Where:
S = slip
N = actual speed in RPM
Plugging in the values, we get:
S = (1000 - 960) / 1000
S = 0.04 or 4%
Therefore, the slip at this speed is 4%.
