Pretty sure this is a 3000 rpm motor. I tried slower motors but they didn't have the speed to consistently knock big bugs down. It is a small fan motor, standard 3.3 diameter, totally enclosed air over type, some small fraction of a HP. Would be best if I got the Grainger part numbers for you and you could look at the specs on their web site. There's a million places you can buy motors just like it. I used a fully enclosed motor because of being more weather and debris tight. You wouldn't believe all the bug parts that fly all over. Being enclosed it requires the cooling fan ($4) to blow air over it. I also had to experiment with the size of motor so it was able to swing a reasonable length weed whip line without overheating. It has automatic thermal reset so if it overheats it will shut down and restart when cool. Only cost around $30. I'll look up all part numbers and get back with info. The motor size, fan blade, and weed whip length need to all be matched for this to work without overheating and still be as low power as possible so if I give you part numbers you can avoid experimentation. I think total cost was about $60 but it's bigger and gets more bugs than most. Very low power draw with small motor and flourescent bulbs. I've got two of these that I've run for 3 years now with no problems other than occasionally cleaning the line when it gets coated thick with bug guts. Despite its speed and power you'd be surprised how many bugs just get injured versus killed. But even the dead ones get eaten.
