We will now analyze the values of emfs E1m and E2m at under-load operation, when the current of the stator winding is 0 defined as I1 ¼ Im + (ÀI2 ). 24). 31), it follows that x12kE ¼ x21kI ¼ x22k2 ¼ x11. , (ÀE1m) ¼ (ÀE11) ¼ 0 0 jx11Im ¼ jxmIm and E2m ¼ E12 ¼ E11. These conditions for the emfs of the stator and rotor windings are valid for both no-load conditions and under-load operation of an electric machine. This provision was demonstrated above on the basis of physical considerations. 33)   0 ðÀE1m Þ ¼ ðÀE11 Þ ¼ jx11 I m ¼ jxm I 1 þ I 2 ð2:34Þ where xm ¼ x11.

36) using the referred secondary values has a simpler structure. 26), introduction of leakage reactance value is based on the use of the provision that the leakage fields (fluxes) cover turns of only one or the other of the windings. However, this provision is not sufficient for quantitative determination of the leakage reactance values, as it does not reflect the real picture of the coverage of the stator and rotor windings by the leakage fields. 36) can be considered. We can assume that the load components of the currents flow in the stator and rotor windings.

31), we have I1 ¼ À I2 . 29) as (ÀE1m) ¼ (ÀE11) ¼ jx11Im ¼ jxmIm, where xm ¼ x11. 1 An Induction Machine with a Single-Winding Rotor: Voltage Equations. . 0 27 0 of the rotor winding emf is E2m ¼ E12 ¼ E11. We will now analyze the values of emfs E1m and E2m at under-load operation, when the current of the stator winding is 0 defined as I1 ¼ Im + (ÀI2 ). 24). 31), it follows that x12kE ¼ x21kI ¼ x22k2 ¼ x11. , (ÀE1m) ¼ (ÀE11) ¼ 0 0 jx11Im ¼ jxmIm and E2m ¼ E12 ¼ E11.
