Motor Drive Voltage #134

Description

@ab-tools

Hello @Lenti84 and @SurfGargano,

first thanks a lot for all your work, really great project!

I was wondering which voltage you are driving the HmIP-VdMot actuators with?

If I understand the schematics provided correctly, this is the voltage regulator which provides supply voltage to the motor drivers:

And if I don't make a mistake in the voltage calculation based on the LM2596 data sheet, then:
V+ = 1.23 x (1 + 10000 / 1682) = ~8.54 V.

Is that correct and if so, really curious, what's the reason to use this specific voltage? :-)

Thanks in advance for your feedback
Andreas
