| description | An apparatus and method are provided for stiffening a base plate of a spindle motor to improve shock resistance and vibration response, and thereby increase reliability and performance of a disc drive memory system. A stiffener tab for stiffening a base plate is connected to the base plate, extends from the base plate, and is dimensioned to fit adjacent to a stator tooth. Stiffening of a base plate is especially useful in the case of stamped base plate designs that typically have uniform thickness, whereas cast base plate designs are formed with thicker sections. In an aspect, the present invention stiffens a motor cup portion of the base plate, and replaces stiffness lost by removal of material from the base plate to form holes for recessing a stator into the base plate. Axial and angular displacement of a spindle motor during shock events and vibration are decreased. |
