Webthe case of synchronous generator operation, we can think of bar A (the rotor field) as pushing bar B (the armature field), as in Fig. 11a. In the case of synchronous motor … WebThe percent impedance is defined as the voltage drop across the reactor as a percentage of nominal voltage. ... So the formula for Percent Impedance would be as follows: %Z = L (in Henries) / [(V L-L / 1.732) / (I x 2π x F)] x 100% . Author: Rick Akey Date: 12/18/13 External
WebJan 9, 2024 · The phasor diagram with all the above details at normal excitation is shown below. When the value of back emf is equal to applied voltage E b = V then the synchronous motor is said to be at normal excitation. The angle θ is called an internal machine angle or impedance angle. It is constant for a motor. WebSep 12, 2024 · Figure 14.2. 1: Some of the magnetic field lines produced by the current in coil 1 pass through coil 2. The mutual inductance M 21 of coil 2 with respect to coil 1 is the ratio of the flux through the N 2 turns of coil 2 produced by the magnetic field of the current in coil 1, divided by that current, that is, (14.2.1) M 21 = N 2 Φ 21 I 1.
