Abstract:
1. A torque motor, comprising: a rotor; and a stator, the stator including a stator frame with iron cores and electrical windings arranged thereon, the iron cores and the electrical windings are arranged in at least one independent stator segment so that each stator segment is independently operable, each stator segment having its own housing, in which the segment's iron core and the segment's electrical winding are installed, each stator segment being configured to occupy a predetermined angular segment ≦180° in the stator frame, whereby at least one angular segment in the stator frame is by design not occupied by any stator segment, each stator segment being detachably joined to the stator frame so that the segment can be installed and removed independently of other stator segments without damaging its electrical winding or the stator frame.
