WebA Design D motor is a squirrel-cage motor designed to withstand full-voltage starting and to develop high locked-rotor torque as shown in MG 1-1.37 with locked-rotor current not greater than shown in MG 1-12.34 for 60 Hz and MG 1-12.35 for 50 Hz, and having a slip at rated load of 5% or more. WebIf the load increases, the speed of an induction motor decreases, and slip increases. As the slip increases, the term (sX20)2 becomes high compared to Rotor resistance R2. And in …
WebNov 16, 2024 · At High Values of Slip : When the slip of the motor increases beyond its maximum value, then the motor is said to be running at high values of slip. When slip is further increases beyond s = s m, then the resistance of the rotor R 22 is very small as compared to the reactance of the rotor (sX 2) 2 and it can be neglected.
