Abstract :
The effect of height on power density is examined for the practical ranges of power, frequency, loss, and volt-per-turn. Relevant mechanical and electrical equations are derived and applied to an optimization algorithm which searches for the design which maximizes the power density at a given height. It has been found that the curves of power density versus height exhibit a peak, on the order of 1000 W/in 3 in several cases, at a critical height between .25 to .3 in. Below this critical height, the power density decreases drastically
