Re: Skillnad på motorkondensatorer och vanliga kondensatorer

Tack, bra att känna till!
En del kondensatorer kommer alltid att vara inkopplade medan resten skulle regleras via spänningsavkänning (avr) men till att börja med blir det nog manuellt.
Bäst är tydligen att använda en 3-fas motor som enfas generator - se nedan:

"Nominal voltages of the motor must be 220/380V (nowadays 230/400V) which is intended to connect as the star.
The bigger motors are often 380/660V (400/690V), which is intended to connect as the triangle.
This is not a good choice as you can find when reading the results. There is no central or neutral point so the monophase 220V load cannot be used."
"The most shocking finding with these results is that the threephase squirrel motor acts the most best as a generator when the electric load is monophase.
As you know usually it is aim to deliver the electric power as equal as possible to all the three phases.
But thinking so is not a good idea here."
