Opening Source Excerpt
Section titled “Opening Source Excerpt”XII. Conclusion 103. Of the types of machines, converter, inverted converter, and double-current generator, sundry combinations can be de- devised with each other and with synchronous motors, alternators, direct-current motors and generators. Thus, for instance, a converter can be used to supply a certain amount of mechanical power as synchronous motor. In this case the alternating current is increased beyond the value corresponding to the direct current by the amount of current giving the mechanical power, and the armature reactions do not neutralize each other, but the reaction of the alternating current exceeds that of the direct current by the amount corresponding to the mechanical load. In the same way the current heating of the armature is in- creased. An inverted converter can also be used to supply some mechanical power. Either arrangement, however, whileSource-Located Theme Snippets

If the secondary of an induction machine is connected to a second induction or synchronous machine on the same shaft, and of the same number of poles, the combination runs at half synchronous speed, and the first induction machine as frequency converter supplies half of its power as electric power of half frequency to the second machine, and changes the other half 262 ELEMENTS OF ELECTRICAL ENGINEERING as motor into mechanical power, driving the second machine as generator. ...Impedance / reactance

One advantage of this type of machine for phase control is that it requires no additional reactive coils, as the induction machine affords sufficient reactance.

Modern Engineering Reading Prompts
Section titled “Modern Engineering Reading Prompts”- Radiation / light: Compare the chapter’s radiation vocabulary with modern electromagnetic radiation, spectral frequency, wavelength, absorption, and illumination engineering.
- Impedance / reactance: Translate historical opposition terms into modern impedance, admittance, conductance, susceptance, and complex-plane notation.
Ether-Field Interpretive Boundary
Section titled “Ether-Field Interpretive Boundary”- Radiation / light: Radiation and wave language can invite ether-field comparison, but source wording, modern radiation theory, and speculative synthesis must stay separated.
Promotion Checklist
Section titled “Promotion Checklist”- Open the full source text and the scan or raw PDF.
- Verify the chapter boundary and surrounding context.
- Promote exact quotations only after checking the source image.
- Move mathematical candidates into canonical equation pages only after formula typography is corrected.
