Gentle persons: I've admired the brushless DC motors used in radio-controlled aircraft for some time. Their power and torque per size and weight characteristics are mindboggling (and a testament to the evolution of magnetic material in the last ten years) but I worry about their ability to run in our applications without frying themselves.
In a model airplane they typically run for 5-10 minutes and have tons of aircooling. Can they run all day in a CNC-mill? If they weren't so expensive I'd buy several and strap them to an instrumented testbed. As Ben Franklin wrote "experience is an expensive teacher" and I'd rather someone else make the investment :-) Regards, Kent ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
