WebNo. of armature amp-turns/pole for compensating winding=0.7 p Z 2 =0.7 armature amp-turns/pole Commutation: the currents induced in armature conductors of a d.c. generator are alternating. These currents flow in one direction when armature conductors are under N-pole and in the opposite direction when they are under S-pole. WebSep 25, 2024 · a stationary armature may be cooled easily because the size of the armature can be increased to provide more cooling ducts. Since the rotating field is comparatively light, it can be constructed for high speed rotation. The forced cooling with gas or liquids can be easily provided in stationary armature type alternators.

WebMar 24, 2024 · Alternators Question 3: When excitation of 3-phase synchronous motor increases, then. (a) armature current increases and then decreases. (b) power factor … lighters collectableWebSep 2, 2015 · Answer: Its very simple, because there three phases in alrernator so we need a total of six terminals to get the ouput current that is why the winding coresponding to the three phases are individually opened to get the terminals. while in a dc machine there is only one phase so we need only ... lighters collectiblesWebThe frequency of an alternator is directly proportional to the rotational speed of the alternator. Number of poles. If we add poles to the alternator, we can change the frequency. In a two-pole alternator, Side A of the armature (seen in Figure 53) passes from north to south, and then south to north, to create one complete sine wave. peach in nepaliWebThe magnetic field is rotating inside the stator of an alternator. In the case of a generator, the magnetic field is stationary or fixed where the armature winding spins. 8: Armature Movement: The armature of an alternator is stationary. The armature of a generator is rotating. 9: Input Supply: The alternator takes input supply from the stator. peach in meaningWebWhen the load connected to the Alternator varies during the latter’s operation, the generated voltage also varies. This is because of the voltage drops in armature resistance R a, armature leakage reactance, X L and voltage drop due to armature reactance, X a. The armature reaction is due to the action of armature current flux and field flux. lighters collectionWebAlternator Quiz. 1. In air-crafts, alternators have operating frequency of. 2. Alternators, now-a-days, are designed to have poor regulation because. 3. Voltage regulation of an alternator is usually. 4.
