Abstract:
A step motor adapted to be driven by a three-phase driver, comprising:a two-phase bifilar winding stator having a first and second sets of stator coils corresponding to the two phases of said stator; anda rotor magnetically interacting with said stator;wherein at least one stator coil from said first set of stator coils and at least one stator coil from said second set of stator coils are electrically regrouped to form a third set of stator coils, the remaining stator coils of said first set of stator coils form a fourth set of stator coils and are connected to a first phase of said three-phase driver, the remaining stator coils of said second set of stator coils form a fifth set of stator coils and are connected to a second phase of said three-phase driver, the stator coils of said third set of stator coils are connected to a third phase of said three-phase driver.
