Converting manual shutters to electric

[urad29]

Hi all,
I have shutters which are outside the window which are raised and lowered using a manual crank on the inside. I am looking for a way to make it automated with the option of a manual override. I have attached a suggestion of what I would like it to look like. I do not want a tubular motor which means I have to start fiddling with the actual shutter installation; I would prefer a motor which simply turns the 7mm Square shaft and has a manual override option.
Any suggestion would be appreciated.

Thank you!

Without knowing if theres already an aftermarket add-on, some kind of high torque gear motor will probably work with a smart relay etc.. hardest part will be making some kind of braket to attach the motor to wall and lining it up. shouldnt be all too difficult in all honesty. you'll just need to figure out how much torque and power you need to operate the shutter at the speed you desire.

You'll also have to consider some safety aspects too, open window, person under it etc..

Thank you for your response. I'm not too worried about open windows/doors (as they all open inwards) and person under I'm not too concerned about.
I've done some looking around and having some trouble locating a motor that will fit the bill. Any ideas? What further info do you need?

something like the below might be suitable, but it will really depend on how heavy the shutters are. You'll need to investigate the required torque you need for your shutter. Then decide on the voltage and RPM you want to work with.

Then probably some kind of L bracket to securely mount it on the wall and in line with the shaft along with a shaft coupler to couple the existing 7mm shaft with the motor. Proably trial and error but hardest part might be the logic / programming of the smart interface. How will you know when the shutter is fully open/closed etc.. limit switches or sensors.

some of the suggestions above dont really have a manual override but you can possibly incorporate some kind of quick disconnect maybe? Probably not ideal still, theres drill attachments for awnings/shutters but that doesnt take into account your automation. But essentially you just need a suitable motor.

Thanks!
I think limit switches are probably the best. I'm having a little trouble locating a motor with manual override but I'll keep trying.

In the second picture, is that the "shutter" we can see through the window? If so, I would call them "Venetian blinds", probably a lot less torque required than a shutter.
How are you going to sense open/closed?

 

[urad29]

These are the blinds. I don't think they need to much torque, though they are quite wide.
I would use limit switches to detect when the blinds are all the way up or down.
My plan was to use the manual override to turn the slats either up or down as the crank only needs to be turned a tiny bit to do this.

 

[omega015]

oh wow, good spot @Why Not Indeed . Yup significantly less torque needed and some of those motors what I suggested may be way overkill.
