Hi GUYS
which of the following electric motors for a bench top belt /disc sander would be the stronger motor when it comes under load pressure from sanding.
1. 240v 850 watts ( axminster )
2. 110v 1 hp ( unknown name as yet) ?? .hc

1 horsepower = 745.699872 watts so the axminster jobbie is going to have a bit more power, but as its such a small difference, I doubt you'd notice unless you were really forcing it, and thats not good for the machine anyway  |

Hi davyowen
Would the difference between the 240v & 110v make and difference when it comes to load pressure , i dont mean forcing it in any way at all just wondered which would slow down if pressure was placed on it . dont want to buy either if it's likely to be underpowered when (any) no matter how light the load placed on it .hc

I had a record power RDS150 which was rated at 1/3HP @ 240v and I put some pretty reckless force onto it when trying to grind a straight edge onto a piece of bronze and it barely slowed down so I don't think you'll have a problem with the axminster machine.
Regarding voltage, the only time it will make noticable difference is when comparing single phase to triple phase (more torque on 3-phase) and when it comes to power being reduced by voltage drop (lower voltage means more current required for a given power output, more amps flowing means higher volage drop, less volts means less power...)
