115V vs. 230V for variable speed Bader?

I'm happy to say my new 1-1/2 HP Bader BIII just arrived. It has the Leeson variable speed DC setup.

The system can be set to run on 115V or 230V AC. Have any of you used this setup at the lower input voltage? I know that it's probably much more efficient at the higher voltage, but it will take me a week to get an electrician in to run a 230V line to the back of the shop. I was wondering if I could expect reasonable performance at the lower voltage until I can get the line run. This would allow me to get started working with the machine tonight. I can always switch the system to the higher input voltage when the line is run. As always, your inputs are very much appreciated.

Thanks,

Not yet. I can hardly wait. It's got to be a thousand % better than the clunker I've been learning on.

 
It dosn't matter which of the input voltages
you use from a power consumption standpoint.
You pay for your electricty in killowatt hours. Watts=Volt x Amps
If your grinder draws 10amps at 115volt=1,150
watts.Running it at 230volt your current draw
will be cut in half, 5amps x 230volt
= 1,150watts. About the only thing you will
save on is the cost of the wire if you hook
it up with at 230volts,but you will need a
double-pole breaker which will cost more
and will probably wipe out the savings on the
wire unless you have to run it a long way.

cvestal you are right concerning power consumption. Besides this there are other important points. Here in germany we don't have 115V. The normal lines are all 230V 1-phase and if you want to work with power machines you can get 380V 3-phase everywhere. You won't believe the difference in power even with same consumption of energy.
I have worked the same grinder with 230V and 380V and with the 230V it was possible for me to stop him from running by pushing a blade on the platen. Same thing was absolute IMPOSSIBLE with the same machine running on 3-phase electricity. I think it may be the same difference in power tom mayo is talking about.

The motor set on 230V will start quicker than the same one set on 115V. Power consumption is about the same but since the 230V motor starts quicker, it will last longer. Try not to start and stop any electric motor more than absolutely necessary, Starting is the hardest thing on any motor

OLd_engineer your speed controller will output the same DC voltage to the motor
if run at 230volt or 115volt.
I've run a Variable speed BurKing at 115volts
for about 3 years with no problems.
I don't think it would worth the expence
of running a new 230volt line.

Hope this helps.
