Re: Confused over My own Calculations!

Thanks Dave:

I understand what your saying, but it just does not make sense that a
the name plate rating would be specifying any particular mode such as
bipolar or series or whatever unless it specifically says so.

I take the amp rating to be the maximum amperage on any one winding.
All the other specs such as ohms refer to only one winding.

If a motor has 8 leads or 4 windings, then each winding can handle up
to 3.5 amps, and if you tie two of the winding together in parallel,
then that pair can handle 7 amps. Then you tie the other 2 together,
then that winding pair can handle 7 ampers also. So the total motor
current is 14 amps.
Take this same motor and connect in series, and each winding pair can
handle 3.5 Amps for a total motor current of 7 amps.

Is what your saying is that the stated maximum current is the TOTAL
maximum motor current in any configuration? Now that just might
penetrate my thick skull. But, in that case, you would think a better
spec would be maximum wattage.
