What voltage are you going to run it at?

I think we need some more input from the group on how much current is needed to get that motor moving. I see 0.3A at maximum efficiency, can't tell what the stall current is, that's what your power suppply will have to source your drive circuit be capable of switching.

Hi,

I cant see the stall current on that motor data either.

The voltage it will be run at depends on how fast I want the shaft to rotate as this will dictate how quickly the door will open at.

Preferrably Id want it running slower rather than faster so between 6 and 12v.
