Abstract (en)
[origin: DE10107688A1] A thread supplying device (F) provided with a housing (1) containing an electric motor wherein the stator (S) is non-rotatingly mounted and the rotor (R) is rotatingly mounted on a motor shaft (W). A thread guiding element (E) is fixed to the motor shaft (W) and a threader device (T) which is fixed to the housing is also provided. When the motor shaft (W) is in a set position of rotation (Y), the thread guiding element (E) must be physically associated with said threader device. A permanent magnet motor (PM) with pole cores provided with windings is integrated into the stator (S) and permanent magnets are integrated into the rotor (R ) in such a way that the stator (S), rotor (R ) and the thread guiding element (E) are arranged relative to the housing (1), in relation to the axis (X) of the motor shaft, in such a way that the motor shaft (W) adopts the set position of rotation (Y) when the permanent magnet motor is devoid of electric current in a stable relative position of rotation (DLS), caused by magnetic forces, of the rotor( R ) in the stator (S).
