hello again with a little absence
time to find a good multiplier
420tm multiplier output shaft + 30cm pulley
I think to put an asynchronous motor of 6 kw cos 0.84
220volt what capacity of the star capacitor
or in a triangle
I promise I will send you photos

I believe that to have an idea of ​​the value of the condenser, it is necessary to apply the formula of rectification of cos-phi.
Basically you calculate to get a cos-phi of 1
The value is naturally dependent on the voltage and therefore on the coupling of the condos.
I do not remember the formula (my lessons are far) but it should be easily found on the net.

Hello everyone
I just bought a 4kwa asynchronous motor
at 920 laps with the gear reduction it should rotate at 1200tm
or a little less due to the pressure drop
I have 3 10µ oil bath condenser
can you give me an idea on the regulator that i can put
or find one
or use a diode bridge and a mounting shema
by adding 3 meter
for voltage and voltage amperage
thanks again

Hi Fredo!

What do you want to get as a voltage output?

What do you want to power and is phase accuracy important?

For a precise and valid answer, the question must be clear and precise:
however, we cannot know if the motor is three-phase or single-phase ??
If the mains current is single-phase or three-phase ???
in doubt, impossible to give an answer.

Give the brand of the motor its precise characteristics, even its instructions, three-phase or not, assembled how for sale, the characteristics of the capacitors in voltage, current and power, the precise and clear objective etc.

Finally help yourself by being precise, clear and the sky will help you !!

Otherwise read the basics:

LOL!

Hey ben my dear Dede, it only lacks the use it wants to make of it, it is clear that it speaks of three phases by quoting 3 capacitors of 10mfd and the connection in triangle or in star! Either you misread or it doesn't fit in your strings!

The capacity of the condos depends on the load exerted on the output, if the load varies the use of a motor in gene becomes problematic!

[fredo24]

yes hola little forgetfulness on my part
the motor is three-phase used in 220 volts
to supply 3 or 4 electric heaters at first
and after if possible power the heat pump
thank you

Fredo


There are Chinese generators 6 kw for really cheap which you could recover the gene to produce your electricity without all the problem linked to the use of an engine which is not specially designed for the use in generator.

[dedeleco]

I hadn't guessed the goal!

An asynchronous generator motor needs an electrical starting excitation at the motor rotation frequency !!

Excitement is not at all essential. The remanent flow is generally enough to start the generator (I already had the experience once)

On the other hand, an asynchronous generator to supply a heat pump. You might as well forget it right away, it's going to be very difficult and of a reliability at the height of the daisies.
