previous patents the United States notably those numbered 381,968 and 382,280, dated May 1888,1 have shown and iS described system transmitting power by meansof electro-magnetic generators and mo­ tors. Let designate ordinary type alter­ nating current generator the circuit of which Connected motor motors, according present invention. But secure rotation I- make, for example, the cores short with 80 their coils close their inner ends and the cores long, with their coils removed from the inner ends. secure this result the two currents must have different phases, the 25 best results being obtained when the two cur­ rents differ quarter phase, other words when the periodsof maximum potential of one current coincide with the minimum pe­ riods the other, and conversely., ASSIGNOR THE TESLA ELECTRIC COMPANY, SAME PLACE.United States Patent Office. 288,677. end view modified form of 50 armature for said motor.) To all whom concern: Be known that Nikola Tesla, sub­ ject the Emperor Austria-Hungary, from Smiljan, Lika, border country Aiistria- 5 Hungary, and resident New York, the county and State New York, have invented certain new and useful Improvements Elec­ tromagnetic Motors, which the following is a specification, reference being had the to drawings accompanying and forming part of the same. SPECIFICATION forming’part Letters Patent No. Each these cores surrounded energizing coil 65 and all these coils are connected the main circuit from the generator series or any other manner receive simultane­ ously the current impulses delivered the generator. have 30 also discovered that single alternating cur­ rent may utilized produce progression or shifting the magnetic poles motor if the field magnets the same differ­ ent magnetic susceptibility different parts 35 that the magnetic phases the same will differ. con­ struct such motor motors the following 55 manner: shaft mount armature C, which for convenience illustration pre­ sumed soft iron plate disk with two cut-away portions bar with rounded ends. ApplicationfiledO ctober 20t 1888. Around this armature place say four poles, 60 D soft iron, and, usual all alternating current machines, built in­ sulated plates sections prevent the heat­ ing that wouldotherwise occur. The distinguishing feature this sys­ tem was shown the progressive move­ ment shifting the magnetic poles or zo points maximum attraction motor, due to the action effectof alternating currents passed through independent energizing cir­ cuits the motor. Fig. the cores are all the same 70 shape mass, composition, and the coils are all wound the same alternately op­ posite directions, rotation would pro­ duced the passage through the coils a current, whether alternating direct, since 75 the attractive forces the poles upon the soft iron armature would developed simul­ taneously and would counterbalance neu­ tralize each other. NIKOLA TESLA, NEW YORK, Y. That say, the field magnets are of such character that their different portions will differently magnetized—in respect to time—by the same current impulse, and so 4 disposed that the difference magnetic phase will maintain i-otary progressive shifting the points of,maximum magnetic effect.

The ef­ fect being virtually produce shifting of the points maximum magnetic effect simi- 95 lar that which takes place when two alter­ nating energizing currents, differing phase are used, explained the patents above referred to. The essential difference being that patented system the rotation ef- 100 . this means secure a difference the magnetic phases which the poles exhibit, for while the short cores will 85 respond the magnetizing effect alter­ nation impulse current the coils a certain time, greater interval time will elapse before the same magnetic intensity will developed the ends the longer 90 coi’es, and practice have found that this difference phase may utilized pro­ duce the rotation the armature.
