A rotor assembly includes a substantially cylindrical support structure having at least one first region, and at least one second region. At least one rotor coil is positioned within each first region of the substantially cylindrical support structure. Each rotor coil includes a pair of distal end portions and a convex center portion, and the average mechanical density of the convex center portion is substantially equal to the average mechanical density of the distal end portions. The average mechanical density of the at least one first region is substantially equal to the average mechanical density of the at least one second region.
