EXERCI SE 1

A tliiec-phase induction motor, at standstill, has a rotoi voltage of 100 V between the slip-rings

\vlien they are opeli-circuited. The rotor winding is star-connected and has a leakage reactalice of I fl/Jilaase at standstill a url a i esistance of 0.2 O/phase.
i . I Calcnlate the rotor ciii rent at a slip of 4% anal rotor cil-cuit closed,
1.2 Calciilatc the s lip and i otor ciiii eiii when the rotoi’ is tlevcloping uiax i mmm torqiie. Assiiinc the fiiix to be constant. (I 1.33 A ; 0.2 ; 40.8 A)

A lluee-pliase, 50-Hz, slip-ring, star-connected, inductioli iiiotor gives 500 volt between slip-

rings at standstill. The resistance per rlias e of the rotor is 0.2 £I/pli and the indnctance is 0.04 I I/pli.

Calculate the rotor cunent and power-factor at standstill when the rotor winding is connected to an cxtci nal irrqictlancc of 10 D anal 0.04 H.
Calcnlate the i ofor cruz ent and power-factor with the rings sliorterl and the slip being 5% XXXXXXXXXXA; 0.376; XXXXXXXXXXA; 0.303)
