What would happen to the output of an AC generator if one of the stator windings has an open?
There would be a significant decrease in the output of the generator. Depending on the type of generator, it could stop working altogether.
How do you test a stator on a skidoo?
To test a stator on a Ski-Doo, first, disconnect the electrical connectors and use a multimeter to measure the resistance between the stator's windings. Check for continuity between the windings and ensure there's no short to ground by measuring resistance from the windings to the stator case. Additionally, you can test the output voltage by starting the engine and measuring the AC voltage at the stator's output wires, comparing it to the manufacturer’s specifications. If the readings are outside the specified range, the stator may need replacement.
How can a 24 v battery start a 80 kw emergency generator?
The 24v battery is used to provide the initial field current. This couples to the stator windings, and as the generator spins induces a voltage on the stator windings, which causes back EMF onto the field windings (when load is present), which slows the generator's spin until the governor kicks in to bring it back up to speed. The important thing to note is the output power of the generator is not a factor of the 24v field voltage, it is directly dependent upon the fuel being used to get the generator spinning. The 24 volts just "jump starts" the field voltage. Think of it as synonymous with the 12 volt battery that starts your car.
Is slip ring a part attached to each end of the wire loop in an ac generator?
In a very simple, laboratory-type, a.c. generator -yes. In practical generators, the output (armature) windings are part of the stator, so do not rotate and, so, don't require slip rings.
What are field windings and armature windings in a dc motor and generator?
generators have two types of winding , * at armature also called armature winding( winding around shaft , we can say), which is the moving part. note that armature also consists of magnets along with windings. hence produces field arount it. * and at stator also called field winding, because when armature rotates its flux(field) is cutted by the stator windings and produces mutually induced e.m.f in it( in stator windings off course) causing current to flow. this current also produces some electric field around it which is in return cutted by the armature windings hince a little amount of e.m.f ( also called back e.m.f) produced in armature due to stator winding current. know this current in armature (due to back e.m.f produced by stator winding) produces additional field , hence causing more current in stator winding. this is the reason that why stator windings are called field winding( as they cause electric field of armature stronger and cause more current in output). note that out put is taken from the stator windings in generators.

Does armature rotates?
Typically the armature windings are in the stator of a generator, which does not rotate. Typically the field windings are on the rotor, which rotates.

What are the causes of failure of d.c shunt generator to excite?
no residual magnetism in the stator. this can happen with an overload which will occasionally even reverse the output polarity

How does a generator make energy?
A generator doesn't store energy it just transforms it typically from burning a fuel (like gasoline) to mechanical energy (like an internal combustion engine) then from mechanical energy to electrical current.
What is needed to generate AC electricity?
An AC generator (Alternator). A rotor is turned into a magnet by what is known as 'excitation' current. The rotor then induces AC current in the stator windings as it is rotated within it. This is AC, due to the fact that the rotor has a north and south pole, which alternately induces current in the stator windings. The exitation current is provided to the rotor via slip rings. Controlling this excitation current will also control the output power by suitable control circuitry. This is the same principle, whether it is a small domestic generator, a power station, a wind turbine, or a car alternator.
What affect does a changing magnetic field strength have on an ac generator power output?
By increasing the field current (current flowing through the rotor windings), the magnetic field generated by these windings will increase. This increased magnetic field will result in a larger current flow in the stator windings (the output of the generator). This in turn causes a larger pull against the rotation of the rotor, causing it to slow down. The governor will then kick in, allowing more steam/ power to the prime mover to keep speed steady. Assuming all is working correctly, the output power will increase as the magnetic field is increased (to a limit).
Can be excitor stator pole and main stataor poles are equal?
In a synchronous machine, the excitation stator poles and the main stator poles are not equal; they serve different functions. The excitation stator poles typically produce a magnetic field generated by the rotor windings (or field windings), while the main stator poles are part of the stator winding that produces the output voltage and current. The interaction between these poles is essential for the machine's operation, but their characteristics and functions differ.
