Hi, Newby here trying to design a small piece of lawn equipment in my shop. I want to design my own leaf blower using a small electric motor to turn the shaft of a squirrel cage blower. A friend of mine built himself this same system except he used an old lawnmower motor. It works great but I wanted to try an electric motor, instead, to avoid the noise and pollution. Naturally, my next thought was to power it with a 12 volt battery so I'm not dragging a cord around. I have no idea of the type and size motor I would need, if it would work fine with one 12 battery or if it would need several. If I understand correctly, there are 12 volt DC motors I could use so I don't have to buy a converter but I have several electric motors in my shop and I'm trying to do this as inexpensively as I can. My original idea was to have 2 batterys, one being used on the cart and one charging so I can swap out when the first battery runs low. This machine would probably not be used continuously for more than 2 hours at the most and the squirrel cage fan is not extremely large(it measures ~16"x18"x6" wide). I had planned to run an ordinary fan belt from the blower shaft to the motor shaft. Let me know how feasible or how "stupid" this idea is and the basics of how it could be set up. Thanks.
