The Electromotive Force, (emf) induced in a Coil is proportional to the number of turns, N, in the Coil and the Rate of Change of the number of Magnetic Flux Line passing through the surface (A) enclosed by the Coil.
In the rudimentary generator illustrated here, the Coil is under a Stationary Magnetic Field.
A careful plotting of induced emf through one rotation of the coil reveals that a sinusoidal voltage waveform is the natural result of the mechanical motion of a generators coils.
For example, in position A on the illustration of the coil rotation, the loop is cutting no lines of force so the induced emf is zero (point 1 on the graph.) One quarter turn later, the loop is in position B.
In the past, attention was given to portable generator features such as automatic voltage regulation and speed regulation.Introduction Given the wide variety of generators manufactured for different markets, it is important to understand the benefits and drawbacks to each when it comes to their use in motion picture production.Especially, given that the increasing use of personal computers and microprocessor-controlled recording equipment in HD production has created an unprecedented demand for clean, reliable power on set at a time when the trend in lighting is toward light sources that generate dirty power.With this knowledge we will be able to also parallel two Honda EU6500 or EU7000 generators for an unprecedented 100A or 120A output from putt-putts.To deliver this power safely under hazardous conditions, this knowledge will enable us to develop reliable ground fault protection systems using film style GFCIs, like the Shock Stops, that are specifically designed for motion picture applications.
