I find motors direct very helpful and reasonable, usually with a choice of price options.

To make replacement straightforward check the motor dimensions and mounting sizes. On most motors the speed, shaft dia and hole spacing for the mounting feet are standard. Hopefully you will be able to fit a more powerful motor but keep the sizes the same.

There is a good chance that your 1.5Hp motor has a 90 frame. The frame size governs the height of the shaft centre above the mounting feet and generally the shaft size too (24mm).
Sticking with same frame size will remove a number of difficulties.
You should be able to find 90 frame motors up to 3hp but they will have longer bodies and may foul on the casing of your saw.
The trade off will be to go up to a 100 frame, solve the issues of a larger shaft (28mm shaft) and needing a longer belt Vs sticking with a 90 frame and nibbling away at the case to allow it to tilt over the full range.

Good luck
