Brushless motor control
Torqueless - As being without torque. Other machines only drive one side of a frame (one design uses a single motor and fixed gearing between the main frame and the inner frame) and use a simple bearing on the other side. It wouldn't matter if the molds that get mounted on the machine were...- RadioGold

Brushless motor control
Your getting too personal we hardly know each other! The motors are 9v 150w max. A pic is a pic is a pic and the esc's are gone. For anyboby else out there what's the easiest why to drive these motors (min. parts) and the programming is not an issue. I don't mine puting a pic on each motor if...- RadioGold

Brushless motor control
Right now I have 2 pic's and esc's on each motor. 1 pic runs the 2 main frame motors via their esc's. It also hooks to a PC via USB to get program instructions. It transmits the speeds and cycle times to the 2nd pic running the inner frame (the frames run independently). There is no feedback...- RadioGold

Brushless motor control
I have a site: http://www.coldgold.rotoquad.com The machine is under the "Roto Casting Machine" link. The machine is torqueless. The drive is better distributed. I use gearing so I can use small motors but more important I need to monitor the speed (hard to do on a frame doing 10 rpm)...- RadioGold

Brushless motor control
I produce a 4 motor rotocasting machine (as it rotates 2 aluminum frames, one within the other, the load on the motors is constantly changing). Taking the example for one axis I have 2 sensorless bl motors (spinning in opposite directions) connected to gearboxes (250:1) spinning a frame...- RadioGold

Electric / thermal mineral separating method
To electricuwe, VE1BLL, Higgler Thank you all for your replies. I suppose I could buy 1 or more CB amps on eBay? But that would only be the beginning of what’s required. Also I do not have a HF oscilloscope. Because this is not my particular area of expertise (HF / KW equipment) I’m really...- RadioGold

Electric / thermal mineral separating method
Hello my name is Colin Wilson and I am the inventor of a new mineral separation process. http://www.coldgold.rotoquad.com I am looking for help and/or a partnership in this endeavor. As a group I can not think of a better place to start. To test this new method of mineral recovery 3 things are...- RadioGold
