I will buy the DC servo motor to charge the battery from the UPS
the ups will work as invertor to change 12 V to 220.
but my DC servo motor is 36V.
any comments on this ?

Can you reveal the details of your new design? How will you turn
the generator? It makes a big difference.
Let's say for argument that you plan to connect the servo to
your bicycle to generate electricity. Fine! Just place a diode
in series with the servo so that it doesn't discharge your battery.
Keep an eye on battery current and voltage. You now have an
educational tool that will give you an appreciation for the work
that a power generator does.
This is not a practical power source, however.

brought and it looks good.

How about using a solar charge controller fpt 24v batteries, that will take
care of two major issues, they will charge the batteries correctly and can
handle the higher voltage that the dc serve delivers.
24v inverters are common and two equal (same age / type / user pattern) 12
batteries can be put in series to make a 24v battery with 1/2 the current
running through your wirring to the inverter per given wattage, ie. lower
loss in wirring...

look on ebay for dc motors Permanent magnet type. I have 2 40vdc tape drive
motors that do not require 40vdc to run. They generate a varied voltage at
various rpm. All you need is a charge controller or a speed controller on
the mill. key search word on ebay : ametek Available from 12vdc up to 90
vdc Used mainly on wind generators...same type motor as in the picture you
are looking at.
