Abstract
A spindle motor in a disc drive has a rotor assembly rotatably mounted to a base. A stator is mounted to the base and a magnet is mounted to the rotor assembly. The magnet or the stator is allowed to move in an axial direction relative to the other under the influence of magnetic interaction between the magnet and the stator. The magnet and stator are then rigidly fixed relative to one another in the axial direction.
