Question about Powermatic 66 10" 3 HP 1 Phase 230V Table Saw w/ 30" Accu-Fence & Rout-R-Lift 1660806K

1 Answer

The saw starts but ramps up slowly. Under load the blade slows down. Seems as though the motor is not getting enough power or there is an issue with the motor itself. Any suggestions?

Slows down and stops when trying to cut hardwood


You just do not have a saw that has enough power, the blade is dull or both. Change your blade and push the wood through slower or get a more powerful saw for the hard woods.

I have a TS300 table saw and the blade does turn immediately when power upped, the blade speed seem low, and the blade easily stall when cutting - even 1/4" ply.


There are two windings in the motor, a starting winding and a running winding. There's also a centrifugal starting switch in the motor that switches from the starting winding to the running winding once the motor gets up to speed. Sometimes the switch can get stuck and you almost have to give the blade a spin with your hand to get it moving-- and then it moves slowly till it picks up speed.
A rating on that saw complains it doesn't have a whole lot of power, but yours doesn't sound like its under-designed -- it sounds like there's something wrong. Does it smell hot when running? Does the arbor turn freely? Are you using a long extension cord? (dont!)
I hope you don't need a new motor ($255)
If you do, I'd sell the thing for parts on CraigsList and look for another saw in the same place. I bought one table saw on craigslist for $60 and another for $45. (You might have to watch the listings every day for a year or so to get those kind of prices.) Both of the ones I bought are belt-drive contractor's saws with a 1.5 hp motor outside the box on the back side of the saw.

While cutting a 2x4 at a 45 degree (small load) the motor quit after 12 inches. seems like i should be able to rip a 2x4


How would you rip 12 inches if your riping a 2x4 on a 45 secondly the blade of that saw and weather or not you were cutting through the grain on treated lumber. But if all that has been checked chances are one of the brushes on the motor need replacing. there are usually 2 black caps on both sides of motor that have replaceable brushes if one stops making good contact you get half power when cutting. You can check them and or replace if needed.

Saw has lost cutting power


Open the side cover and inspect the blade path and blade tension. Rotate the blade by hand looking for interference at any point. Make sure the drive pulley is not slipping on the shaft and that the belt is not loose or badly worn. Make sure the two large drums that carry the blade turn easily (dry bearing?). Does the motor slow down? Are the drum rim surfaces (rubber) in good shape? If the tension device is at limit, but not tightening the blade, the blade may be too long.

Tile saw began having trouble starting. I would


Your motor brushed sound like they're gone bad. Some electric motors have two small plugs on the side which house the brushes. See if yours has this and get new parts. The other possibility is that the bearings are corroded and has built up enough resistance to stop everything.
Might not be able to replace those, however.

Circular saw engine question


it's important to choose a tool with a motor that is powerful enough to meet your needs. For example, a woodworker should choose a saw with enough power to cut through everything from wet lumber to dense hardwood. If the motor in the saw you select doesn't have enough power, the blade heats up and begins to dull. In addition to creating poor quality cuts, this can become a safety hazard if the blade starts to climb out and push the saw back towards the user. However, evaluating power from the motor ratings can be misleading. Amps indicate only the amount of electricity a motor draws, not the power it sends to the blade. Horsepower accounts for torque (rotational force), but not necessarily under working conditions. So be careful and ask the seller if this particular tool suits the work you want to be done.
