Effciency gains can be 4-6% on a PWM drive --
1.33*Motor HP x hrs operating x Cost/KWH x Effciency Gain = savings in electricity costs
Thus for a 100hp motor at $0.10 / KWH at 5% gain
it will save about $5890/yr savings in electricy costs
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
