A magnetic field will not generate an EMF if there is no motion, so the primary factor causing a permanent magnet generator to not generate EMF is if it is not turning.

Which factors affect performance of magneto?

A magneto is an electric generator that is powered by magnets. Some factors that will affect its performance include their power source as well as the reliability.


What determinesthe amount of current produced in the armature of a generator?

The amount of current produced in the armature of a generator is primarily determined by the voltage induced in the armature winding, the resistance of the circuit, and the load connected to the generator. According to Ohm's Law, current (I) is equal to voltage (V) divided by resistance (R) (I = V/R). Additionally, factors such as the speed of rotation of the generator, the strength of the magnetic field, and the number of turns in the coil also influence the induced voltage and, consequently, the current generated.


What is the RPM for ac generator to get 240 volt?

'Speed' is only one of the factors that determine the output voltage of an a.c. generator, so your question cannot be answered. In practise, speed is more important establishing frequency rather than voltage.


How is the induced voltage of separately excited dc generator affected if the exciting current is reduced?

In a separately excited DC generator, the induced voltage is directly related to the magnetic field strength produced by the field winding, which is influenced by the exciting current. If the exciting current is reduced, the magnetic field strength decreases, leading to a reduction in the induced voltage. Consequently, the output voltage of the generator will decrease as the field strength diminishes, assuming all other factors remain constant.


How much fuel does a eighty kva diesel generator consume per hour for no load?

An 80 kVA diesel generator typically consumes around 1 to 2 liters of fuel per hour when running under no load. This consumption can vary based on factors such as the generator's efficiency, maintenance condition, and specific model. However, it's important to note that fuel consumption is generally higher under load conditions. Always refer to the manufacturer's specifications for more accurate figures.

How much electricity is produced by 350 RPM?

That's a much more complicated question than you would first think. A generator that operates at 350 RPM would be very rare. To better answer the question, a short overview of how generators work is needed. To generate electricity, wires are moved through a magnetic field. The stronger the magnetic field, or the faster the wires are moved, the tougher it would be to move those wires, and the more electricity is generated. A typical generator (especially what you would find in a power plant), uses electromagnets to generate the magnetic field. Due to many different engineering concerns, the speed of the turbine remains constant (3600 RPM is a common speed, though lower speeds are not uncommon). If more electricity is needed, the electromagnet's power is increased, which generates a stronger magnetic field. Then, it is up to whatever is turning the generator (usually some sort of a turbine) to provide more power to the generator to keep the RPM the same. There will be some sort of a limit on the generator, where applying more power could overload the electromagnets, or damage the generator shaft. The important thing to notice is that whether that generator is providing 2 megawatts or 55 megawatts, it is turning exactly the same RPM. So, this whole answer boils down to this: it varies. It will depend on the generator, on what's turning the generator, and what load is on the generator. Those three factors often have to be balanced against each other. If the generator has permanent magnets, then you can predict how much electricity it will generate at 350 RPM. That will depend on the strength of the magnets, and how many coils of wire are used. However, if the load on the generator doesn't match generation, the RPMs at the generator will increase.


How do you convert a fan motor to produce energy?

Converting a fan motor to produce energy typically involves mechanically connecting the motor to a generator or alternator. As the fan motor spins, it can generate electricity through the generator/alternator. However, the amount of energy produced may be limited by factors such as the motor's power output and efficiency. Consulting with an expert is recommended when attempting this conversion.

What thing can we do to increase the size of the current the generator produces?

To increase the size of the current the generator produces, you can increase the strength of the magnetic field, increase the speed of rotation of the generator, or increase the number of turns in the generator coil. These factors all contribute to the overall output of the generator.
