  • Patent number: 6215616
    Abstract: A spindle motor for a disk drive includes a shaft, an upper bearing, a lower bearing, a stator, a hub and wire guide body. The upper bearing surrounds the shaft. The lower bearing surrounds the shaft, is spaced-apart from the upper bearing, and includes an inner race. The stator surrounds the shaft between the upper bearing and the lower bearing, and includes a stator wire extending from a stator core. The hub is concentrically positioned about the stator. The wire guide body is secured between the shaft and the lower bearing, and includes a generally cylindrically shaped surface and a channel. The channel is sized to receive the stator wire and is formed adjacent to the cylindrically shaped surface such that the channel opens into at least one of the shaft and the inner race.
