摘要
A disc drive having a housing which encloses a clean room that is provided with a brushless DC drive motor having an external rotor and three pole shoes on a substantially ring-shaped stator for each two pole on the rotor. The stator winding is commutated by a three-phase commutation network in such a fashion that first, second and third networks in the stator winding are cyclically connected to an external DC source in accordance with rotor position. Each of the networks comprises at least one stator coil wrapped around a neck of a single corresponding one of the pole shoes.
