Abstract
A brushless DC motor in which increased rotor resistance is used to facilitate very frequent reversals. The rotor endcap is thinned down to the point where the resistance seen by the path of the current loop through one of said endcaps, is at least one-half as much as the resistance seen by the portion of said current loop which flows along the length of one of said rotor bars.
