In certain embodiments, a motor includes a shaft positioned adjacent a sleeve for relative rotation. The sleeve includes a first radial recirculation channel. The shaft and sleeve form first and second gaps. The first gap is configured to form a pump seal, is positioned above the first radial recirculation channel, and has a width measured between the shaft and sleeve. The second gap is configured to form a journal bearing, is positioned below the first radial recirculation channel, and has a width measured between the shaft and sleeve. The width of the first gap is greater than the width of the second gap.
