Principles of direct current machines by Langsdorf, Alexander Suss, Publication date Topics Electric machinery -- Direct current Publisher New York [etc.] McGraw-Hill book company Collection cdl; americana Digitizing sponsor MSN Contributor University of California Libraries Language English.

Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps. OF SYNCHRONOUS MACHINES The synchronous electrical generator (also called alternator) belongs to the family of electric rotating machines. Other members of the family are the direct-current (dc) motor or generator, the induction motor or generator, and a number in this book the angle between the current and the voltage in the circuit will File Size: 1MB.
Electricity could be produced in a number of ways, and entrepreneurs were eager to capitalize on a growing and unregulated industry. Faradic, galvanic, wet and dry cell batteries, and static electricity produced direct current for home devices before indirect current was available to power larger machines in doctors’ offices. - Buy The Performance and Design Of Direct Current Machines (Pb ) book online at best prices in India on Read The Performance and Design Of Direct Current Machines (Pb ) book reviews & author details and more at Free delivery on qualified orders/5(8).

Direct-Current Machine an electric rotating machine that converts mechanical energy to DC electrical energy (a Direct current machines book, or vice versa (a motor). It is reversible—that is, the same machine can operate both as a generator and as a motor.
For example, traction motors of rolling stock and servomotors of high-power DC electric drives operate in this way.

DC machines are the most versatile of all rotating electrical machines. Their speed may be easily adjusted in very fine increments ranging from standstill to rated speed and even above. • DC machines can develop rated torque at all speeds from standstill.

Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion electric current flows in a constant direction, distinguishing it from alternating current (AC). Direct Current Machines.

This chapter discusses the nature of the main design problem associated with direct current (DC) machines and oscillogram of DC machine armature-coil current, and it gives a schematic representation of a DC machine, coil circuit during commutation and typical current-reversal curves and brush curves; it shows a simplified diagram of a coil in a.
Abstract. Historically, DC machines were the first to be developed because the only available electrical power source was the DC voltaic cell. The advantages of alternating current were later recognised, and the invention of the induction motor was an important factor in Author: J.

3 Principles of Direct Current Machines Introduction. Direct current (dc) machines operate on dc voltages and currents. Recall from Chapter 2 that time-varying currents flowing through properly placed windings can lead to generation of a rotating magnetic field.
Direct currents do not vary with time, and it may seem puzzling at first glance how they may result in rotation. Direct current machines by M.
