What is better to feed a 500W asynchronous motor?

AI Thread Summary
Feeding a 500W asynchronous motor can be done with either an asynchronous or synchronous aerogenerator, but the choice depends on specific needs. An asynchronous generator is simpler but relies on grid support for voltage and frequency control, making it less suitable for off-grid applications. In contrast, a synchronous generator can operate independently of the grid, providing a more reliable power source in remote settings. The definition of "better" hinges on the application context, such as whether grid connectivity is available. Ultimately, the choice should align with the operational requirements and environment of the motor.

TL;DR Summary
Since some days ago, I were looking the anawer for this question for a project I'm working on but I don't find something accurate on any part.
What is better to feed a 500w asynchronous motor, an asynchronous or synchronous aerogenerator of 1kw? Why is a asynchronous/synchronous aereogenerator better in this case? Thanks you

A question well stated is half answered. This one is neither.

Always define your terms.By aerogenerator i assume you mean windmill as opposed to an aircraft generator.
Definition of aerogenerator

: a wind-driven electric generator designed for utilization of wind power on a commercial scale
What do you mean by "better" ?
A garden variety motor won't know the difference between generators so long as voltage and frequency are reasonably controlled.
An asynchronous generator has control over neither of those parameters , so is simpler in concept but requires some sort of grid for excitation and frequency control.
But a synchronous generator can provide power in absence of the grid so would be logical for off the grid application.

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
