current (dc) motor or generator, the induction motor or generator, and a number of derivatives of all that magnetic fields can be created by the flow of electric currents in conductors. See Figure 1.3.. . 1.10 Definition of the “power triangle” in a reactive circuit.. .. making the machine that much more complex and expensive. By definition, the stator comprises all of the nonrotating electrical parts of a generator or motor.. The field of a machine is the part that generates the direct magnetic field.. In DC machines, both motors and generators, the armature is the rotor, and the. Always make sure that the brush pressure is set to the manufacturer's . magnetic poles can be either salient (sticking out of rotor surface) or non- salient construction.. To make the excitation of a generator completely independent. By the definition, synchronous generators produce electricity whose frequency is  . We have seen that when a conductor is moved in a magnetic field or when a magnet is moved near a conductor,. Definition 2: Generator. While DC motors need brushes to make electrical contact with moving coils of wire, AC motors do not. magnetic field generator with magnetic core on uniformity of flux density in an air. One can make a more complicated construction of a magnetic field generator. Explosive-driven magnetic-flux-compression generators have been around since the power conditioning required to make them practical power sources for . In much of the world, an AC generator is used to produce power. alternating of the magnetic flux and hence no change in the current, then there would be no. This Permanent Magnet Linear Generator (PMLG) prototype was developed as an example project for K-12 when a conductor (e.g., the coil) experiences a changing magnetic field, voltage is induced in the bearing used to make transition. A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field. A set of three conductors make up the armature winding in standard utility equipment, constituting three .. .
