The motor you have can't be converted to variable speed. The best way to go is to switch to replace you single phase motor with a 3 phase one, and then use a variable frequency drive (VFD) to control the speed. You could also get a DC motor with a controller, but it will probably cost at least as much and not perform as well. Hitachi VFDs are popular here.

That is for a DC motor.

Shop around for a 3/4 or 1hp Baldor 3 phase motor with the appropriate size output shaft. Then buy a 1hp 110 input Teco JNEV series VFD. Fit the motor, wire up the VFD, enjoy! If you want more useability, spend some money on a control box with start, stop, fwd/rvs and speed controls.
Motor- $50-100
VFD- $150
Buttons/enclosure- $150-250

Only if you buy a 110VAC input type. Otherwise it might be 220V but they are all single phase input (this their value). I believe the 110VAC input type typically only go up to 1HP and I know the Teco is probably the more common of them. The FM50 is a cheaper TECO than the JNEV series but not worth it in my opinion because it doesn't allow for digital inputs (simple on/off buttons).
Also- the JNEV is being replaced by a newer version of the JNEV with a different name, which escapes me right now. When I reviewed the differences, the main difference seemed to be that the 110v input and 3ph output are both on the top now versus top and bottom, respectively. Not really a big deal.
