A labyrinth seal system of the present invention is found in a motor having a ball bearing ring, a shaft, and a labyrinth seal washer. The ball bearing ring has an inner bearing ring with an inner ring surface. In one embodiment the labyrinth seal system includes a shaft having a first shaft portion with a first shaft diameter and a second shaft portion with a second shaft diameter. The first shaft portion has a first outer shaft surface and the second shaft portion has a second outer shaft surface. A shaft shoulder may be formed between the first and second outer shaft surfaces. The second outer shaft surface is at least partially annularly adjacent the inner ring surface. Also included is a labyrinth seal washer having an annular leg that is positioned at least partially between the first outer shaft surface and the inner ring surface. The labyrinth seal system includes turbulence zones interspersed with narrow flow zones.
