    High speed motor for sinusoidal shaker?

    Thanks guys. I think everybody is right about the flywheel. Now I have to do some calculations to size the wheel. I better make sure our safty guy is not around when I run this beast! This is turning into a fun project mostely because I am not sure if it will work or not....

    High speed motor for sinusoidal shaker?

    I dont think my original motor link worked. Here is the one I was considering: http://www.astroflight.com/store/pdffiles/3220.pdf The torque I mentioned is peak so I think a flywheel is a good thought. The Idea of alot of inertia spinning at 15k scares and excites me at the same time! Thanks...

    High speed motor for sinusoidal shaker?

    I think the fly wheel is a godd thought as that figure is peak as you guessed I dont think my original link worked correctly but here is the motor I was thinking of: http://www.astroflight.com/store/pdffiles/3220.pdf Anybody know a convenient way to power this guy? 7 hp at 4 lbs is quite...

    High speed motor for sinusoidal shaker?

    2.5 ft lbs at 15k rpm is around 7 hp not 1 I think. As I said my research has pointed me to brushless DC which I have used in model aircraft in the past. What I am not sure of is how to power such a motor. I have done some research online but I am a bit confused. Is there an easy off the shelf...

    High speed motor for sinusoidal shaker?

    Hello all, I am new here and look forward to contributing and learning. I am trying to design a "shaker" with a fixed sinusoidal discplacement (~.02" P-P) with a max freq of around 250 hz (15krpm). I was thinking of using a electric motor with an eccentric crankshaft and some sort of conecting...
