I wonder if this uses an 8 pole motor to get the direct drive ~1000
rpm? *Multiple pole motors (I believe) get you more torque, but it may

No, it's plain old belt drive. *The motor is an ordinary 60 Hz two-pole motor,

One can download the brochure and manual from this webpage.

Ok, I see. *I should have looked at the Northern Tool website myself

have a C-face type motor with couplings instead of using pullieys.
