## Question:

Find the induced torque in the motor in Problem (A 220-V 1.5-hp 50-Hz six-pole capacitor-start induction motor has the following main-winding impedances:

${ R }_{ 1 }$ = 1.3 $\Omega$ ${ R }_{ 2 }$ = 1.73 $\Omega$

${ X }_{ M }$ = 105 $\Omega$ ${ X }_{ 1 }$ = 2.01 $\Omega$ ${ X }_{ 2 }$ = 2.01 $\Omega$

At a slip of 0.05, the motor’s rotational losses are 291 W. The rotational losses may be assumed constant over the normal operating range of the motor.) if it is operating at 5 percent slip and its terminal voltage is

(a) 190 V,

(b) 208 V,

(c) 230 V.
