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...
Throughout the year the regular design work of the
class room proved so profitable that it was thought that
there was no subject which could be selected for thesis
purposes of greater benefit,or which offered as great a
latitude in the working out of the various problems, than
the one...
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 problem of the economical transmission of power has long been a serious one to the engineer. Formerly the power had to be generated on or near the spot where it was to be used, but now the advance that has been made in Electrical Engineering has largely done away...
In order that the proper motor for a given service
may be chosen it becomes necessary to study and know
the requirements and characteristics of the machine which
may be used for that purpose. When these are known the
selection of that one which is best adapted for the use...
