Hi, i am a newbie, and I recently made an impulse buy on a great deal. An old man was going out of business on his machine shop, and I bought from him a 4 hp compressor motor that was in brand new condition for $65. The motor has the following specs:
Hertz 60, phase 1, rpm 3450, volts 230, thermally protected, type – continuous, amps 15, maker- Gould Century
When I got home, I read on an old online post from someone who put on a 5hp motor on his table saw and said that it made “the top sag,” whatever that means, due to the weight of the motor. I have a 1984 Craftsman table saw with a cast iron top and 1hp motor, and i recently bought some white oak and ash wood to soon make my workbench. The wood is 7 inches wide and 3 inches deep. Btw, it kind of irks me that, with this 10” table saw, the maximum thickness it can cut is only 2-1/2”. I assumed all 10” saws would cut deeper than that when I bought it, duh on my behalf. Last night, I weighed the 2 motors. The 1hp motor weighed 24.5 lbs, and the 4hp motor weighed 37 lbs. Now, with this table saw, the motor hangs off the back where it would turn should I need to cut at an angle (I predict that I will just keep it at 90 degrees over 95% of the time). I noticed the 4hp motor has a pulley on it where it looks like it was made for two belts. I was going to install a link belt on the table saw. Would I have to put on two link belts? I saw 5hp cabinet saws advertised as having a triple belt system. I assume the extra belts are due to either the extra power or weight of the 5hp motor.
Is this 4hp motor too heavy for this contractor saw? Or, should I just install this motor onto my band saw?
My 14” band saw has a 6” pulley on it where, if I install a 1-1/2” pulley on the motor, it will have a proper sfpm of 3160. I used this calculator to figure it out:
