The induction motor in its electromagnetic features
is essentially a transformer, while in its general behavior
it is analogous to the continuous-current shunt wound
motor. In a transformer the primary and secondary members
are both stationary and electrical energy is transformed
from one pressure to another by the ratio of...
Samples of insulating materials used in the construction
of electrical machinery and apparatus are
tested for dielectric strength before such are accepted
for use. This is done by applying to the sample a
high voltage until it is pierced through by the electric
spark. This is a parallel case to...
This thesis comprises a series of tests run on a compound direct current generator and an induction motor; separately and combined as a set, with sheets of data; characteristic and efficiency curves and deduction drawn therefrom relative to the two machines.
The designing of electrical machinery is fully
as essential to the thorough understanding of power
equipment and apparatus, as is the taking of a laboratory
testing course. One learns the relationship
of the different parts, the methods of computing
their dimensions, and the predetermination of outputs,
efficiencies, etc. and thus...
