Ive never timed it but it started my combo machines and they are a bigger shaft with a saw and mortiser other end. If it doesn't work, I'd consider a static phase converter next, or a single phase motor, as better options than a giant RPC.ġ0 HP roto blips to 165 amps for a split second no issues idles at around 17 no load, is quiet not noisey and and would start that jointer full speed in less than 2 seconds.

Lots of folks have had success with it on at least 3 HP motors. A planer is a different animal but if yours is only 15 - 18' wide 2/3's of 5HP would be more than adequate unless you wanted to take huge cuts with it. We jointed a couple of 12' wide boards on it and could not discern any appreciable loss in rpm compared to our other jointers. Wiring it was simple and it operates just like any other motor, but at only 2/3's the rated HP. It didn't cost much on the order of $100. The standard 3- 5HP unit took 5 - 6 seconds to bring the cutterhead up to full speed the upgraded unit does it in 3 seconds. By upgraded I mean the guy who built it, WNY Phase Converters who I talked about earlier, used much larger and higher voltage rated capacitors than in a standard unit. Food for thought, I just finished installing an upgraded static phase converter on my friends 3 ph, 5 HP, 16' Zefam jointer today.
