Can Anyone Help with Old Import 4x6 Horizontal Bandsaw?

admin

When cutting .25" wall 2" square tubing, the motor started shaking and  then some smoke started coming from this little wiring box area.It shortly thereafter stopped working, remained in the on toggled position and when I tried restarting it, it won't start.I  know little about these. Bought it used very recently, moved the blade  guides and got new blades and got it to cut squarely but now this.Not sure if that's fixable or if it's now a goner. Any help greatly appreciated!

Reply:I can't tell for sure by looking at your lowest picture, but it appears you had arcing between the two right (input?) wires and the top of the box. If so, might you have thrown a circuit breaker for the outlet the unit is plugged into? Besides examining those wires more closely, you might start by checking continuity between the power cord plug's connectors and the motor windings. If OK, open the motor to check the starting circuit or windings (may be a split phase type).Or, maybe the lower conductor is actually broken?
Reply:Looks like one from Post Tool.The one had the motor die I just replaced the motor with  ⅓hp size motor and better than new. I also replaced the switch Dave

Reply:replace the motor with a "real" 1/2 hp motor.  It will literally run better than when new.  weight can be an issue since a motor will be heavier an may require weight redistribution. i would not bother repairing that motor. you or they probably have/had been operating at reduced power for a long time before it quite.

Good possibility the smoke may have come from the capacitor to the left of the J-box. Who knows for sure, those chinese motors are cheap junk any way, I'd just buy a decent replacement.
Reply:The motor is junk Dave

Used to be able to scrounge small motors from washing machines and such, but for decades, those motors are skeletons to reduce cost and weight. I still have barrels full of stuff like old, good motors.
Reply:Looking at the photo it definitely is using what appears to be a start capacitor. It's possible that it's a start/run capacitor. I'd start by checking the capacitor. Next check the winding resistance. I'm suspecting you may have burned the windings in which case you may need to pull the motor apart to verify. I'd also carefully check the terminal block.
