Start Capacitors & Run Capacitors for Electric Motors - Differences Explained by TEMCo

Hi will a microwave capacitor 1.1uf 2100vac 50/60hz can be charged by 12 volt battery ? Can it be used to between the battery bank and inverter to not let the battery bank take the brunt of electric initial draw. Saving battery. ?

Very well done.
Thank you

have a single phase century 5 hp 1800 rpm motor, has a 330 volt 408 to 480 mfd cap that blew.
it runs with a 220v cap i have in stock, similar mfd range, is that ok to use in an emergency?

In simplest terms, if a motor is running slow, it could be because of bad run cap, not start cap, cause that won't running at all then right

Order capacitor located on a

Would you capacitor located on a

Do you have to change capacitors with exactly the same one or is similar or close capacity ok

Are common and run terminals on single run capacitor interchangeable since there are no markings?

I need a lil help.. I am trying to get a pool pump motor to run off of my dc to ac inverter and just hums and then the inverter shuts down. I think if I add a start run capacitor to the circuit it should work fine. I am hoping .. it’s a 120 volt 12 amp 60 hrtz motor. Which start/run capacitor do you recommend. I am thinking a CBB 65 will work. But don’t want to blow the motor.. any suggestions ?

How do I find what value start capacitor to use to replace an unmarked one? The motor is 230vac, 12A, 2hp, 1ph. I can not find any info for the 40 year old motor.

Is it a good idea to install a start capacitor if compressor run capacitor keeps blowing? Could this keep the unit working for a while until it can be replaced?

How do you know what size compasotor to replace the compasotors with if there's no label or writing on the old compasotors and there's 3 compasotors on this air compressor and how do I find out what one is the start and run on this compressor?

Get yourself a SnufferStick to discharge thise caps. Much safer. Or make one.

Run capacitors should have a 1.5 vac ratio... 😳.. If your using 220 ac power source... Then your capacitor vac rating should be 220x1.5 =330vac rating, at least to compensate for surges..😀👍

😍👍

mpp cap 350v 12uf size replace it with a 12uf 450v
Will that be ok

Well done

a run capacitor will not blow up in line while a start will explode? in line with compressor

Replacing a run cap on a bandsaw, the original is a 2 prong and the replacement has the same values but is a 4 pin. If they’re interchangeable does anyone know which pins do I connect to?

Sound not to a good level.

I can’t tell you how many capacitor videos I’ve watched. This video gave it to you in layman‘s terms it shows you a start capacitor had to run capacitor and how they work. Very good.

Who let the smoke out?

Thank you. Very informative video

can you use a microwave capacitor as a run capacitor on a treadmill motor?

Thank you! Great video!

I do understand the main differences between a run capacitor and a start capacitor and their purposes but what I don't understand is why did replacing the 5uF run capacitor on my spa circ pump motor fix its problem of not starting?

do you ship to Canada?

I wanted to know the power supply voltage you were using we understood it was AC but is that a 120 plug that you hooks to the capacitors directly I want to know it's capability can you put a wall outlet directly to one of those running capacitors?

I have issues with a 220 volt dual capacitor motor, when the motor is switched on, the motor turns but then the breaker cuts in. I changed the start up capacitor with a new one, same issue. I returned the motor to the supplier and waited 5 weeks for it to be returned. Once I received it I immediately plug it in and it started and the bare motor ran. Once I put the impeller on and secured all the parts into the housing, it doesn't start!!
Is the weight of the impeller cause a load for the motor not to start? I changed the start up capacitor again, still same result. I disconnect the breaker from the circuit, it finally started!! But then it died because the start up capacitor began leaking oil.....im lost!!
Can it be the breaker at fault?

Hey how come you guys don’t make capacitors that fit brushless generators. I am talking the half shaped moon ones. It would be nice to have a quality American made part available for Chinese clone generators. I love your other stuff as I use it exclusively in all my air compressors motors I fix.

A great tutorial easy to understand and concise. Thank you.

😮❗👍

They make a great filter capacitors on the cheap for tube amplifiers and last a long time

Thank u for the info sir, this is exactly what I need to know for testing a start capacitor.

What capacitors should I connect to the 400Watt generator, any suggestion please .
I am using capacitors 8 micro farad and as soon as I plug in the light. the power is gon generator is 650 watts

Thang you for that sharing sir.

Good day, Sir can Í asked the correct value of capacitor for 10hp motor 3 phase that can run single phase 220vac. Thank you Sir

Excellent demonstration. Good info on the differences.

Hi there,
I am looking for 6 microfarad x3 capacitor. Could you explain what type 9f capacitor it is? Thanks

Thanks for the information and demonstration. I have one question about start capacitors. I assume they are parallel to the load … ie., across the 240 vac power. What makes it “drop out” of the circuit once it does its work?

What's the different systems of a single phase motor when the start capacitor goes bad and run capacitor goes bad?

Well worth watching.

you may need a capacitor to smooth out your audio signal...:)

Thank you for that sharing sir.

Thank you, thank you, THANK YOU!!!!!!
Looks like I was about to burn my ass…
Thank goodness 😅
