A bandsaw would not be much use without something to make the wheels spin. EBay to the rescue.
Lincoln Electric 3-phase 1 horsepower 1140rpm 208/230VAC TEFC induction motor
I picked this up for about $100 including shipping. It has a 5/8” shaft with keyway, and it’s in fair condition. It was ‘refurbished’ by the seller which basically means they painted it. There is some physical damage to the mounting frame which may have happened during shipping. It weighs about 36lbs. This is a six-pole motor which means it has extra windings inside (more copper and iron = heavier). But a six-pole motor is much better for what I am using it for because with the motor only spinning at 1140rpm, my pulley ratio is 2:1 instead of 3:1 or 6:1, if I were using a 1725rpm (4-pole) or 3450rpm (2-pole) motor, respectively.
I don’t have 3-phase service in my shop, but that doesn’t matter. To power the motor, I am using a Square D VSD07 U18 P20 Variable Frequency Driver, which is a device that rectifies a 60hz AC input into DC, then uses a technique called pulse-width modulation to output a new 3-phase AC sine wave with a variable frequency.
Since an induction motor’s speed is a direct relationship between the frequency of the AC sine wave, a VFD unit can be used to run a motor faster or slower than it’s nameplate rating. You do lose a little bit of power when running a motor too far over or under it’s rated speed, but I’m not sure exactly how that’s calculated.
The other electronics pictured are a Seimens circuit breaker, some terminal blocks, and a LS Metasol magnetic contactor, as well as a 24VDC power supply which will be used to run indicator lights and some other stuff.
