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.

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
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...
