hi. we have a refrigerator that has inverter compressor. but the sound is so loudly according to old one. like 57 dB while working normal speed. if gear up then getting much more like 60 -65 dB. this is normal for inverter ones?
So what is your conclusion, below 60hz the lubrication is inadequate? Another question, im looking for hacking my own refrigerator to control its original compressor with an inverter module, i have a good technical knowledge, but never worked practically with refrigeration compressors, in your opinion its feasible?
inverter type AC like LG uses 3Phase motor and and a controller(frequency), and most of old AC has single phase motor therefore it is not possibles to connect the motor to the inverter module.

111 elektro111, Hi1, i have compressor but don't know if 1 or 3 phase. And VFD (1ph to 3ph) terminals; which are U-V-W, to connect in my compressor wiring Red-Black-Brown. My question is Which wire is which wire? Thnk for the feedback
Inverter compressor are thre phses AC motors but in home are only one phase, so it rectify Ac and convert to DC that is applied to a PWM (Pulse Width Modulator) that not only are in 3 phases but can vay frequency from 53 Hz when motor has 1200 rpm to 130 Hz when goes to 3200 rpm.
thanks for reply, what about voltage? Do you think that any or most of home (one phase) fridge compressors can be powered from variable frequency drives?
witam, po naszemu będzie prościej. Co do napięcia do dokładnie nie pamiętam ale raczej było obniżone na falowniku bo to był IG5 na 400V. Raczej nie ma problemu z zasilaniem z falownika ale w rozsądnych granicach aby nie było problemu ze smarowaniem. Oczywiście mówimy o sprężarkach tradycyjnych a nie o iverterach. pozdr.
a jakiego rodzaju tam jest silnik? bo widywałem przy lodówkach różne patenty do rozruchu, silnik ewidentnie bezszczotkowy, a w takich przy jednej fazie są zawsze kłopoty ze startem. Pytam między innymi dlatego że miałem dobrać UPS do lodówki i przez prąd startu trzeba było znacznie większej mocy ups'a. Próbowałem ją puścić przez regulator na triaku, ale nie miała siły wystartować i ten motyw z falownikiem mnie zaciekawił, a znów nigdy nie trenowałem innych silników z falownikiem niż pracujące w trójkącie z szeregowym kondensatorem, czyli asynchronicznych trójfazowych.
silnik jest bezszczotkowy, układy rozruchowe raczej robią to samo , jest tam kondensator rozruchowy i zabezpieczenie sprężarki. tu na falowniku ładnie rusza prawie od 0 Hz ale sprężarka jest nieobciążona. Jak pracuje w normalnych warunkach to rozruch jest znacznie cięższy. Często przed wyrównaniem ciśnień wcale nie ruszy. Co do startu z przetwornic i zasilaczy z doświadczenia wiem że chinole się palą albo nie są wstanie ruszyć maleńkiej sprężareczki i trzeba sporo przewymiarować zasilacz
The thumbnail tho, seems creepy. It kind of reminds me of those Fembots, from the '70s TV series "Bionic Woman / Fembots in Las Vegas" episode(s), without their faces attached. The eyes were so freaky... and without the face covering, they never turn when it started to attack you. Dead eyes they were. Soulless automatons, but ahead of their time.
Antonio, como puedes ver las dos fases se rectifican a CD y se aplican a un PWM ( Modulador de Amplitud de Pulsos donde se convierte a trifasica y le permite variar la frecuencia desde los 53 Hz cuando el motor gira a 1200 rpm pero cuando el control del sensor de temperatura se ajusta para que genere mas frio el PWM puede variar hasta los 130 Hz con lo que sube la velocidad hasta 3200 rpm creando mas frio. Como puedes ver el motor nunca se detiene solo cambia su velocidad.

in Pakistan technicians are making old split ac units into DC inverter .. to control speed of compressor.. is it possible? and does it have any effect on compressor life>>
its posible, but espencibe, complicated and not reliable. the compresor desing have a tolerance of 30% of speed, beyond that has apear a lubricity and fatigue problems.
This video showind us, that compressor will have lubrication problems if frequency below 30Hz. As it not optimized to run at frequency less than 50\60 Hz.
Hello my Ac compressor is running but why starting 5 minutes after then is compressor sound coming and not cool only hit coming but compressor is also running and hit coming why
The a/c is working with few pcb. And everything is being controlled by them. After u run the system all sensors are sending signals to control board and then compressor will starts and if it’s inverter will start from low speed, depend on demand will speed up
witch is better samsong smart inverter compressor or lg linear inverter compressor

Nice!!! Looking forward to seeing what projects you have in mind for this!
Is it a single phase motor?
Is it three phase compressor?

Search for a "single phase variable frequency drive"
so the compressor speed is working based on input frequency not voltage is that correct?
Absolutely your right
Realmente debe actuar sobre las dos variables, voltaje y frecuencia, pues ambas interactúan de una manera compleja en estos motores. Hay mucha teoría y matemáticas detrás de los variadores de frecuencia.
In all frequecy drivers, when@low frequency the voltage is also low.

How can I get a device like dat... I'm a HVAC tech
you can run a compressor like that with an arduino... im working to figure that out too... Im appliance technician and a hobbiest
This is an induction motor based compressor. Do you have any video of permanent magnet based compressors?
Yes. They won't work on VFD drives. 3ph Brushless driver is needed like for the latest hobby motors.
why they wouldn't work on vfd? the synchronous motors
because brushless are dc motors.
Yes, there are. But they still use commutation to fire the needed coils for right time. (Hall effect sensor)
Thats not true. The controllerr for compresor is dc. Te current in the motor is just 3 phase ac
How have you connected the vfd with compressor can you please share connection diagrams
