Alternator Single Phase Generator Winding Diagram
The winding can either be single layer or double layer.
Alternator single phase generator winding diagram. There are a few single phase alternators out there that claim to do a better job but they are really just a manufacturing cost savings. 1 hp x kva they also provide good performances under a single phase connection. The winding can thus be controlled by controlling the amount of current passing through the conductor causing the magnetic field. It has three completely separate windings in which current is produced but a single rotating magnetic field.
Winding is so arranged in different armature slots that it must produce sinusoidal emf. 240v connections shown in blue 120v connections shown in red double delta connections always provide 240 120v single phase t3. The windings can be classified as. Besides a high pickup capacity motors startup.
The three phase generator is basically three separate generators in one casing. Single phase outputs on some stamford alternators it is possible to reconnect a winding designed with 12 leads for a 3 phase output into a double delta configuration for a single phase output. Refer to the alternator s published technical data for the output kva rating at a single phase voltage. Types of armature winding of alternator.
Single phase generator also known as single phase alternator is an alternating current electrical generator that produces a single continuously alternating voltage. Three phase alternators brush compound regulation 10kva 37kva 50hz 12kva 44 4kva 60hz. The generators of this 4 pole alternator series are three phase with brushes and they are characterised by a compound type regulation on the 3 phases. There are different types of armature winding used in alternator.
The use of this technique is usually restricted to single phase generators with a rated output less than 10 kw. Single phase generators can be used to generate power in single phase electric power systems. 12 slot single phase generator rewinding diagram. Before going to the explanation part you should know about stator rotor field windings and armature.
Voltage developed in the generator windings is a. The coils of wire used to produce a magnetic field are called the field winding and the coils that the power are called the armature winding. The stationary part of an alternator is called the stator and the rotating part is called the rotor. 10 lead generators are not reconnectable as double delta generators connected as zig zag should be reconnected as double delta generators should be derated by 1 3 of their original capacity.
A separate excitation winding in the stator has a capacitor connected directly across its output as shown in fig.
