BT139 & MOC3063

Omid · 2006-09-10T12:09:51+00:00

I have desined a circuit with a Triac (BT139) to swith an AC Motor thatworks with 220 VAC.(Go to this link to see my Circuit )I have used a MOC3063 Optocoupler with Phase Detector capabilities. Iseems work fine. but after some times (maybe some hourse) after runningthe circuit fails and the motor will vibrate and will not rotate. thisproblem will be solve if i changethe MOC3063 with new one. but the same will happen with the second ic.my question is , should iselect another range of resistors with the MOC3063 ?
