Capacitor-Run or Cap-Start motor for a Jointer?

Hi folks,

I've just bought an old 3 phase 9" Jointer and need to obtain a
suitable 240 Volt (UK) single phase motor.

Which type of induction motor would normally be fitted to a
9" Jointer, Capacitor start, Capacitor run, or Cap start and run?
Also what output HP would you recommend?

Capacitor run motors seem to be readily available and the cheapest,
but would they have enough starting torque to spin up a 4" diameter
cutter block (only twin bladed unfortunately).

I'm currently thinking about ordering a 2HP output Cap-start
one from www.NorthernToolUK.com

http://www.northerntooluk.com/product/default.asp?action=&k=&i=&s=&page=&x=0&h=5&g=4&id=912&catId=11&subCatId=85&x=0&h=5&g=4

I tried to order a cap-start and run from Axminster,
but oddly they only do one that runs in the wrong (clockwise).


Thanks,

Mel

I will go for a 2 HP motor then, just in case the manufacturer's quoted output
figures are on the optimistic side.

No this beast's head is circular, I'd imagine a square head would be
rather too prone to causing kick-back.

Thanks,

Thanks for members day tip, I've just registered for their new cat. Don't think
I can wait for the next discount to get a motor though.

Jointer is not a high-torque startup. Induction run ought to do the job.
1.5/2HP would be my choice.

Please tell me that it's not a square head on that beast.

Good deal. Square ones pull things into the necessarily large gap. I'm a
medic with one experience of an ancient square-head jointer (12in, BTW) and
a man with half a palm left ....

Try Machine Mart. Much better quality motors than Northern Tools, and
you don't have to deal with Northern Tools' idiot packing staff and
downright rude telephone staff.

Get on MM's mailing list, wait until the next Bank Holiday special and

No more so that a round head.
