static converter woes

Postby wallace » 20 Nov 2018, 10:47

I run all of my machines via a transwave 5.5kw static converter. It runs everything fine even the 30" bandsaw and 18"planer, I do have to have another motor idling to improve the electrickery for the big stuff. I recently noticed an issue when using my lathe which is only 1.5hp. I have found it bogging down quite easily and can here the boost coming on the static. I've had the static for over 6 years and know what settings it likes for each machine. Could the capacitors for the setting used for the lathe be on their way out?

Highly likely. The run capacitors in those converters are worked very hard. Not an easy job to test without specialist knowledge/equipment. I think transwave will refurbish them for you but no idea of the cost.

Thanks as always Bob, The weird thing is it doesn't seem to affect it when I use it on its highest setting with the big bandsaw. I was cutting some 10"logs up for fire wood and it was fine. It did loose some magic smoke a couple of years ago when a capacitor went all sparky.
Maybe its a bit tired because its about 28 year old

I'm not surprised that you get differing performance on different settings. That is to be expected.

I thought you meant it was 6 years old! At 28 years you are lucky it is working as well as it does.

Failing capacitors will not necessarily release magic smoke although one that does must be replaced.
