I don't think anyone has said that 1 horsepower = 746 watts. Of course nothing is 100% efficient -- electric motors are typically 85-92% efficient, so if your motor is 85% efficient, then you need...

Absolutely correct. I use Permanent Magnet DC motors as an example because the speed is almost exactly proportional to the voltage, and the amps are proportional to the load [torque]. The...
I took industrial controls and other practical courses at my local community (2 year) college, basically to catch up on stuff that has been invented since I got my electrical engineering degree...
Sorry Dana, I have to disagree. W = I^2*R, but a motor is not a resistor. When just starting or anytime running slower than its proper speed, a motor looks a lot like a short circuit. I work with...
I'm also a pilot and electrical engineer. With regard to horsepower, an electric motor can deliver much more than its rated power, BUT there is no such thing as a free lunch. The reason is that you...
My first lesson was similar to the "Good Guy" CFI's description. I meet my first CFI at a company golf league--he was nervous because I'm real clutzy at athletic things. We were both engineers at...
Myself, my wife, and two of my close friends at OSH have Verizon. We did not have any trouble, but we were only using the cell to locate each other and coordinate getting together for forums and...
