Production of a rotating magnetic field
WebbThe magnetic field is rotated by 60º. At 120º ⇒ Phase-B becomes neutral, Phase-A has current flow in a positive direction, that’s why A1 becomes north and A2 becomes south. Phase-C has current flow in a negative direction, that’s why C1 becomes south and C2 becomes north. Webb6 okt. 2014 · Magnetic fields are generated by electric currents. Alternating curents will produce alternating magnetic fields, so the waveform of the current really only tells you how the field strength of the magnetic field will vary with time, it says nothing about rotation with more information. There are several different types of motors.

WebbEduction motor works on the principle of electromagnetic induction. When a three phase supply is given to the three phase stator winding, a rotating magnetic field of constant magnitude is produced as discussed earlier. The speed of this rotation magnetic field is synchronous speed N s r.p.m. Webb7 mars 2011 · This Demonstration shows how combining two or three magnetic fluxes varying in space and time can be used to generate a rotating magnetic field inside an electrical device. The horizontal axis gives the angle in degrees measured from a fixed axis and the vertical axis gives the magnitude of the flux. So at a given time, the graphs for , , …

Webbthe idea of producing rotating magnetic fields without the physical rotation of any member or part. It was realized that a rotating magnetic field could be produced by stationary poly-phase windings carrying polyphase currents by Nikola Tesla and others around 1885. This idea is central to the rotating field theory of a.c machines.
