Abstract

A spindle motor having an annular stator mounted in a housing. The stator and the housing having a joint hole lined by a thin layer of glue forming a cylindrical through bore. A rotor having a cylindrical rotor shaft is rotatably retained in the cylindrical through bore with the stator around and in operating relationship with the rotor shaft. A radial bearing is located between the rotor and the stator.
