A 3-phase induction motor with 4 poles is connected to a voltage source with an amplitude of 209 Vrms and a frequency of 120 Hz.

Ket [755]

Answer:

Explanation:

Calculating Nsync (Synchronous Speed):

$Nsync = 120f/P$

$Nsync = 120 x 120 / 4\\Nsync = 3600 rpm$

$Wsync = 3600 * 2\pi /180\\Wsync = 377 rad/s$

Calculating s (Slip):

$s = (Nsync - Nm) / Nsync \\[tex]s = (3600-2464)/3600\\s = 0.3156$

Calculating Vth (Thevenin Voltage):

$Vth = Vph (Xm / \sqrt{Rs^{2} + (Xs+Xm)^{2} })\\Vth = 209 (76 / \sqrt{(2.3)^{2} + (1.3 + 76)^{2} }\\Vth = 205.39 V$

Calculating Rth (Thevenin Resistance):

$Rth = Rs (Xm/Xs + Xm)^{2} \\Rth = 2.3 (76/1.3 + 76)^{2} \\Rth = 2.22 ohm$

Calculating Xth (Thevenin Reactance):

Xth = Xs = 1.3 ohm

Calculating Torque:

$T = (3Vth^{2}Rr/s) / (Wsync[(Rth+Rr/s)^{2} + (Xth + Xr)^{2}])\\T = (3*205.39*0.7/0.3156) / 377[(2.22+0.7/0.315)^{2} + (1.3+1.8)^{2}]$

T = 280699 / 377 [19.69 + 9.61]
