1. A method of making a spindle motor in a disc drive, comprising:

  • rotatably mounting a rotor assembly, to a base about an axis of rotation;

    mounting a stator to the base;

    mounting a magnet to the rotor assembly;

    allowing one of the magnet and the stator to move in an axial direction relative to another of the magnet and the stator under influence of magnetic interaction between the magnet and the stator; and

    rigidly fixing the magnet and the stator relative to one another to substantially preclude relative axial movement of the magnet and the stator after the one of the magnet and the stator has moved.
