Re: dust collection question
Brian,
Can you tell from the tag if the motors in my CF731 are S1 or S6?
The tag on the CF731 says 3kw but the motors say 2kw.

In actuality Felder should be supplying S7 motors and not S6, as they allow for more frequent starts and stops.

Re: dust collection question
as a concept, i have no issues with duty classification of motors. it allows manufacturer to provide a cost effective solution for each application.
i just have a problem with derating a motor in an application where the load can exceed the derated HP. i hope that in such cases there are appropriate thermal limits or other protective measures to protect the motor because as a user i have no clue what level of load i am presenting to the motor.

Re: dust collection question
The whole European S ratings are a gimmick for marketing, but they can sell a motor that’s S6 on the saw because saws are very rarely running at full load unless it was some automated rip saw that was being power fed continuously. Dust collectors and compressors run at full load all the time, so they get S1 motors.
Here in the US, we rate motors at HP and then give them a duty rating. A 4hp 100% duty rating motor will put out 4hp continuous without overheating and toasting the windings. If you have an occasionally intermittent overload, you might want to spec a 4hp motor with a 135% duty rating, which means it can effectively run at 35% over 4hp continuously without toasting the windings. It’s all about heat dissipation without breaking down the insulation on the windings.
It’s kind of a six of one, half dozen of the other way of looking at things. It just seems a little more upfront with the US ratings because your motor will never be less than the stated hp regardless of the duty rating, where the European standard allows them to call a motor 5hp but you can only fun it at that 60% of the time and it’s actually only a 4hp continuous motor.

i have read this before. i believe this means that a 4hp motor can be sold as s6 or as derated 3hp-s1.
i can see the 3hp-s1 derating work in an application like a compressor where the manufacturer knows that load will not exceed 3hp but how does it work when load is user controlled and in many cases impossible to know, e.g. sawing.
maybe, the derating of motors is only done in applications with known load. i would think dust collector is such application. max load of unrestricted operation is hard to exceed.

infeed roller looks good but the outfeed (steel) roller can stand to be cleaned. is a bit/blade cleaner okay for this?
i tend to use front half for jointing and back half for planing thinking i am using all of the knives length. although, planning is usually a lot more than jointing.
anyhow, i used a lot of cypress last year and the back half of the outfeed roller is not as shiny as the front half. i am assuming it might have resin build up from pushing freshly cut cypress.
thanks,
imran

The "Prime" search returns a different model, the Q0330CP:
The "CP" suffix is the Canadian-certified version.? The QO330 is the true, all-American version.?

I had “prime” selected and the same breaker on Prime is $105.?? On Zoro it’s $115, and one Automation Direct $90.? I can wait an extra week to save
$50.

btw, what kind of panel do you have?? ?$100 for a breaker seems like a lot.? ? If you have SquareD, a 30amp 3P is $50 new on amazon:
There's also a zillion breakers new and used on eBay and you can get this breaker for $20 there.
