N 1.- The diagram in fig.(a) corresponds to the magnetic circuit
of a machine
rotary electric. There are two polar nuclei on which some are
placed.
excitation windings whose mission is to create the flux that passes
through the
induced and this is wound with a winding (not indicated in the
figure) where
the emf is generated of the machine by turning the armature moved
by a machine
external mechanics.
The dimensions are those indicated in fig.(a) and the materials
with which it is
built the machine are: polar nuclei, armature: magnetic
plate.
Cylinder head: cast steel. The magnetization curves of these
materials are the
indicated in fig. (b).
Calculate the number of Ampere-turns per pole needed to produce
a
induction in the air gap of 1 tesla, assuming that the dispersion
coefficient
between the poles and the armature is 1.15.
