Electromagnetic engines, or motors, are machines in which the motive power is derived from electric currents by means of their electromagnetic action. The following design is for a 1½ K.W. bi-polar motor.
A storage battery is a cell. or a series of cells capable of storing up electric energy and giving it off at a required time. A storage battery acts upon the same principle as a galvanic cell in giving forth electric current as the equivalent of chemical energy, but it...
The rapid advancement of electrical science has led it to invade
the field of marine engineering. On ship-board, all ship's lights,
search lights and signal lights are entirely electric. Of power appliances
outside of uses on men of war,ship's ventilation is completely
electric; electric deck winches and boat cranes are...
