Is something like this equivalent to a single phase 220VAC 2HP motor?

Just thinking of how I'll add variable speed to my mill. Would it even need
a reduction set of pulleys or is 1:1 adequate? If the bearings can handle
it a belt ratio of 1:2 to get 6000 RPM?
That motor can produce rated torque down to near zero
speed. But, a belt reduction INCREASES torque as you lower
spindle speed. In some cases like heavy fly cutting, face
mills, boring, and drilling with large diameter drills, you
need that extra torque. When I put my Bridgeport in the
lowest speed range,
the torque is increased by a factor of 22!
