英文: By September 1887 Tesla discovered that he could produce a rotating magnetic field by feeding two separate alternating currents into pairs of coils set on opposite sides of the stator [see illustration on page 80]. 中文: 到了1887年,特士拉发现,他可以将两道分开的交流电导入附在定子两侧的一...
If you made a motor out of a magnet, a wire coil, and some needles, you probably remember that motors and generators depend on a rotating magnetic field. Once you know how it works, the concept is pretty simple, but did you ever wonder who worked it all out to start with? Tesla fig...
But it was very tedious to operate that’s why It was replaced with 2-Phase RMF(Fig 2b) which used AC current supply invented by Nikola tesla. It was more popular but 2-Phase arrangement gives a dip in the rotating magnetic field and in the 3 phase design these oscillations are ...

One should bear in mind that even Nikolai Tesla, one of the most accomplished electromagnetic field researchers, said once that the nature of magnetic fields is one of the most fundamental, if not a fundamental, riddles of nature36. We should thus recognize that for now and likely for a lon...
Magnetic field control of melt motionRotating magnetic fields are of growing interest for crystal growth technologies from the melt. For a few millitesla they provide a controlled motion within the melt, thus controlling the heat and mass transfer and the temperature fluctuations. This paper gives ...

One advantage of the synchronous motor is that the magnetic field of the machine can be produced by the direct current in the field winding, so that the stator windings need to provide only a power component of current in phase with the applied stator voltage—i.e., the motor can operate...
