Triac Driver

[Omid]

I want to control an Electrical Motor that works with 220 V AC.
have you any sample circuit that uses Triac,PhotoTriac and Zero Cross
Detector OptoCoupler for this purpose?

Have you checked out the data sheet sample circuits
that every phototriac, photomosfet devices have?.

Ever since Telstra sacked him form is hole digging job for incompetence .

Have you considered using an off-the-shelf solid state relay? Depends of

course on the size & type of motor, and what kind of control you need. More
information would be helpfull.

I have an Inductive Motor that is used for a Kitchen Hood. I want just
ON/Off the motor . i have designed a circuit with MOC3063(Opto Coupler
with Zero Cross Detector) & BT139 (Triac) . It works well with a Lamp.
but when i replace the lamp with this motor , it doesn't work
correctly, and when i stop triggering the triac(after 2-3 times) it
will continue working and will be hot! , i've read somewhere that i
should use SNUBBER network with R-C , but i dont know values for R & C
.. i have tested with 100 ohm for R and 0.1u for C. but the Capacitor is
burning up!

** You MUST use a mains rated cap like this:

What is X2 class? what's it's name known in the market?

These capacitors are self healing, flame retardant items for
connection directly between The Line (A) and Neutral (N) wires of the
mains supply.

They are generally described as EMI/RFI suppression capacitors. They
are usually rated in Vac (in your case 250Vac) and will be marked X2.

If we disregard the low impedance motor winding in series with the
Triac, the snubber capacitor is connected directly across the Triac in
series with a low value resistor. It will therefore be essentially
directly across the mains supply.

Heres one type available from RS Components

That link is not correct it seems. I should have checked it.

Anyway, here is the manf's data sheet for one type of X2 cap
http://www.evoxrifa.com/cap_catalog/emisuppr/pme271me.pdf

RS Components and other suppliers will have it or an equivalent.

Now learn to post properly - you fucking Google imbecile.

Click on "options" then "reply" !!!

Or else go drop dead.

Thank you All!!!

My Circuit finally worked with your help.

I used X2 Class Cap(0.01u 400V) and R (4W - 170 Ohms)
and it works correctly!
Thanks again.

** We think it 'mazing ......

Why 10nF (0.01uF) capacitor and not 100nF (0.1uF) and why 400V (I
assume it was 400Vac)? Much bigger (physically) than needed.

And where do you get a 4W, 170 ohm resistor pray tell? Standard value
would be 180ohm.

What type is the resistor, metal film/oxide, carbon film, wire-wound?
You only need a 1W carbon film.

BTW are you in Australia where we use 240Vac, 50Hz?

** Nah - the OP never used on of 'em buggers ....

** From a buggerd radio - of course.

** Old.

What is the Best values for my situation , because i want to make
numbers of this board, not just one. maybe it's price deffers!!!!
0.01nf for cap and 180ohm-1W resistor?!!!

BTW are you in Australia where we use 240Vac, 50Hz?
