WebMay 7, 2024 · Figure 10: Induction Machine Torque-Speed Curves Figure 11: Idealized Circuit: Ignore Armature Resistance and then torque is Te = 3 I2 2R2 s = 3p ω V 2R2 s (X1 + X2)2 + (R2 s)2 Now, if we note that what counts is the absolute slip of the rotor, we might define a slip with respect to base frequency: s = ωr ω = ωr ωBωB ω = sBωB ω WebFeb 23, 2024 · P is the number of poles. The induction motor rotates at a speed (N r) close to but less than the synchronous speed. Slip of an induction motor is given by, s = N s − N r N s. ⇒ N r = (1 – s) N s. Where N s is the synchronous speed. And N r is the rotor speed. The frequency of rotor current = sf. talent show mc
