摘要： A rotary absolute signal A is obtained that shows the absolute rotary position at each revolution of the motor based on the output obtained from a rotary encoder 5 affixed to the motor output shaft 2a, and a linear absolute signal B is obtained that shows the absolute linear position per linear stroke pitch along an axial direction 3a of the output shaft 3 based on an output obtained from a linear absolute sensor 6 which is a magnetic induction type sensor and is mounted on the actuator output shaft 3. The distance Lp by which the output shaft 3 is moved per motor revolution and the detection pitch Sp of the linear absolute sensor are set at different values, so in the period until the values become equal, at no point of the output shaft movement is the same absolute signal combination produced. Therefore, the combination of the signals can be used to enable absolute linear position detection over a long stroke.

摘要： The invention concerns a commutator (22; 22a; 22b) for a multi-pole commutator motor (14) having at least four stator poles (16-19) and armature coils (31-42) interacting with them that are electrically interconnected with two commutator bars (1-12) each of the commutator (22; 22a; 22b) to supply current, and the number of which said armature coils is greater than the number of stator poles (16-19), whereby, in order to reduce the number of brushes (20, 21; 23, 24) contacted by the commutator (22; 22a; 22b), armature coils (31-42) forming armature poles having an identical magnetic polarity are connected in parallel by armature-end, electrical bridge conductors (43-48). With regard for the commutator (22; 22a; 22b), it is proposed that the bridge conductors (43-48) are a component of the commutator (22; 22a; 22b). The invention further concerns a multi-pole commutator motor (14) having a commutator (22; 22a; 22b) of this type.

摘要： An improved flat or cylindrical mechanical electric commutator with neutral segments (4) between the current carrying segments which allow the current carrying carbon brushes (11, 12, 13, 14) in a brush holder (7) to pass from a negative current carrying segment to a positive current carrying segment or the opposite charge current in the base of the commutator without allowing the face or any part of the carbon brush to touch both the negative and positive segments in the base of the commutator at the same time, resulting in the switching of the electric current to an energized coil of an electric motor, electrical generator or electric apparatus or device, at predetermined intervals and times to suit the design requirements of the energized coil, electric motor of the stepper, brushless DC and switched design, electric generator or electric apparatus or device, while the commutator can accommodate single phase electrical circuits, double phase electrical circuits, three phase electrical circuits or any number of faces as required by the design specifications, all operating independently of each other.
