Members Doctorx Posted July 25, 2008 Members Share Posted July 25, 2008 What do you mean, "Put together your own motor?" Do you mean choosing a motor? Ebay has Leslie assemblies for auction all the time, see here. Link to comment Share on other sites More sharing options...
Members petejt Posted July 25, 2008 Author Members Share Posted July 25, 2008 What do you mean, "Put together your own motor?" Do you mean choosing a motor?Ebay has Leslie assemblies for auction all the time, see here. Basically just assemble a variable-speed motor system, to rotate my Leslie speaker. I need to know what sort of electric motor would be suitable for this application, where I can get them, what circuitry I need to control the speed (from 0rpm to 100rpm), etc. I want to use a pedal to control the speed. All the motors I find are too fast (2000rpm etc.), and I don't want to muck around with arrays upon arrays of cogs to reduce the speed. Link to comment Share on other sites More sharing options...

I guess it'll have to be from an overlocker, as the motor needs to be small. Link to comment Share on other sites More sharing options...
Members WRGKMC Posted July 25, 2008 Members Share Posted July 25, 2008 Actual Leslie motors are a 2 speed switched motor. Theyre pretty heavy duty to drive fan belts and rotors. AC motors can be trickey things theres a few different types. Many of the higher horsepower ones are phase Frequency dependant. AC servo motors can be varied in speed with pulse width circuitry. My two thoughts besides the sewing machine which is a good idea and can be varied in speed with the pedal, would be a 3 speed house fan or an AC motor with a dimmer switch attached.

Members LordOVchaoS Posted July 25, 2008 Members Share Posted July 25, 2008 I can sell you the real deal brand new for about $60 plus shipping. Link to comment Share on other sites More sharing options...
Members petejt Posted July 26, 2008 Author Members Share Posted July 26, 2008 Actually today I bought a small motor that is 70rpm. They said it can drive stuff that weighs 2kg. I guess that'd be okay? I can sell you the real deal brand new for about $60 plus shipping. So what exactly do you have? I just need the parts for the treble rotor. I have the treble horn.

Members Steverino Posted November 18, 2008 Members Share Posted November 18, 2008 The pics of the setups seen on ebay use what's called a "shaded pole" motor. Link to comment Share on other sites More sharing options...
