Over current protection

MrAL,

Thanks for your reply. The motors will be of the same brand and power so they will rotate evenly. My problem is what motor to use.... i need them to be high in torque, low in speed, operates with 12V or under and not expensive. I think wiper motors will work fine... but before buying them i wish to know if they can handle that load or not?? can someone help me please?? thanks

Hi,

Did you to any torque measurements? It's hard to evaluate a general class of devices like motors when they can vary so much from car to car. It's only possible if you already have some experience with the type of motor or can look up the specs. If you can find the specs and do some torque measurements you might be able to tell from that.

Do you know the approximate torque required for this shutter please?? sorry for asking this question, but im not into motors and do not know the torque needed...

How could we know that, your making it.

and if i use one motor i think it will struggle to rotate a 75" long shaft...

The length of the shaft has nothing to do with it.

If you can get your hands on a dial indicator type torque wrench and rotate the shaft it should tell you how much rotational torque is required.

That's interesting using two motors. If they are the same model it might be ok

Do to mechanical differences, especially in the less expensive motors. One will always work harder then the other.
