Need help for motor driving with triacs


Recommended Posts

Hello people;
I really need help friends
I am tring to drive a single phase (230V AC) motor 4A with BT137(8A), but triac gets hot like 35 celcius degree (even I am using cooler) and after some switching it is getting failed. So that later on I have changed the triac with BTA41(40A) and heatshink, but it is still hot around 30 degree, and in one week BTA41 also gets failing. I am tring to drve the triac with Moc3041, and I am tring to switching the triac when 5Vdc available on Moc3041.
I have tried to use snubber but it is not solving the problem
you can reach the view of my circuit on 

here I am triying drive the motor with 5V dc control to moc3041 so triac fries and the motor starts, and one more think I am also drving a 25uf 400 V capacitor (paralell with the motor) with that motor for compansating

if someone has an advice I will be really thankfull to him/her
Regards

I think the resistor is too small needs to be 330
