battery to run ac motor without inverter

can i connect 20 pc of 12v battery series to run a ac motor ? what is the electronic component needed ? tq

 

Welcome to the forum.

No you can't.

"what is the electronic component needed ?"
It's called an inverter... but something tells me you already knew that.

 

Depends thought. If its a "universal" motor that has an internal rectifier, a motor notionally an AC 110/120 v will happily run on DC as long as the voltage is clean and the amps are there.

@alexandershudai you should probably ask your question on an electronics forum to get the specific detail you are asking for.

 

does not appear to require an internal rectifier,

Up until this moment I would have agreed with Bluebell saying that they are not compatible.

 

" universal motors are usually relatively inefficient: around 30% for smaller motors and up to 70–75% for larger ones."

"the commutator has brushes that wear, so they are much less often used for equipment that is in continuous use. In addition, partly because of the commutator, universal motors are typically very noisy, both acoustically and electromagnetically."
