• The armature resistance was 0. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• As soon as the current flows, the coils become magnetic and attract the soft iron armature, drawing it forward and causing the clapper to strike the bell. 伯莎M.克拉克. 科学通论.
• But immediately afterwards the armature springs backward and makes contact at _P_ and the entire operation is repeated. 伯莎M.克拉克. 科学通论.
• They were then carried through the receiving armature and reproduced on the receiving diaphragm, with all the same characteristics of pitch, loudness and quality. 威廉·亨利·杜利特. 世纪发明.
• The motor was located in the front part of the locomotive, on its side, with the armature shaft across the frames, or parallel with the driving axles. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• The cylinder stops, and current operates the sluggish press-magnet, causing its armature to be attracted, thus lifting the platen and its projecting arm. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• When current is made, the relay attracts an armature, which thereby closes a circuit in a local battery and thus causes a click of the sounder. 伯莎M.克拉克. 科学通论.
• To stop the locomotive, the armature circuit was opened by the main switch, stopping the flow of current, and then brakes were applied by long levers. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• The strength of a motor may be increased by replacing the singly coiled armature by one closely wound on an iron core; in some armatures there are thousands of turns of wire. 伯莎M.克拉克. 科学通论.
• The armature circuit had a switch in it which permitted the locomotive to be reversed by reversing the direction of current flow through the armature. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• Gramme made his armature of iron rods to prevent its destruction by heat. 威廉·亨利·杜利特. 世纪发明.
• By a mechanical device, tape is drawn uniformly under the light marker _P_ attached to the armature. 伯莎M.克拉克. 科学通论.
• The relay coils are connected by wire to the spring piece, S, and the armature lever is connected to earth. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• The presence of soft iron within the armature (Section 296) causes greater attraction between the armature and the outside magnet, and hence greater force of motion. 伯莎M.克拉克. 科学通论.
• To stop, the armature circuit was opened by the main switch and the brake applied. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• After Edison had decided this question, Upton made drawings and tables from which the real armatures were wound and connected to the commutator. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• The strength of a motor may be increased by replacing the singly coiled armature by one closely wound on an iron core; in some armatures there are thousands of turns of wire. 伯莎M.克拉克. 科学通论.
• The heat, of whatever origin, is applied from below, and the shaft being revolved, four of the armatures lose their magnetism constantly, while the other four gain it, so to speak. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• Watson, who helped him construct the two armatures, or vibrating discs, at the end of an electrified wire that stretched from the workshop to an adjoining room. 鲁伯特·萨金特·荷兰. 历史性发明.
• The heating of solid armatures, the only kind then known, and poor insulation in the commutators, also gave rise to serious losses. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• The armature, or moving part of the machine, consists in reality of eight separate armatures all constructed of corrugated sheet iron covered with asbestos and wound with wire. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
• We have calculated armatures and field coils for the new dynamo with Upton, and held the stakes for Jehl and his fellows at their winding bees. 弗兰克·刘易斯·戴尔. 爱迪生的生平和发明.
