A linear alternator is essentially a linear motor used as an electrical generator. An alternator is a type of alternating current (AC) electrical generator. The devices are often physically equivalent.
A brushless alternator is composed of two alternators built end-to-end on one shaft. Until 1966, alternators used brushes with rotating field. [20] With the advancement in semiconductor technology, brushless alternators are possible. Smaller brushless alternators may look like one unit, but the two parts are readily identifiable in the large ...
Modern designs do away with the voltage regulator altogether; voltage regulation is now a function of the engine control unit (ECU). The field current is much smaller than the output current of the alternator; for example, a 70 A alternator may need only 2-3 A of field current. The field current is supplied to the rotor windings by slip rings ...
The in-rush current during re-closure will depend on many factors, however. As an example, a 250 kVA motor–generator operating at 300 ampere of full load current will require 1550 ampere of in-rush current during a re-closure after 5 seconds. This example used a fixed mounted flywheel sized to result in a 1 ⁄ 2 Hz per second slew rate. The ...
A compensated pulsed alternator, [1] also known by the portmanteau compulsator, is a form of power supply. As the name suggests, it is an alternator that is "compensated" (see below) to make it better at delivering pulses of electrical energy than a normal alternator.
This is a list of auto parts, which are manufactured components of automobiles. This list reflects both fossil-fueled cars (using internal combustion engines ) and electric vehicles ; the list is not exhaustive.
In power engineering, winding factor provides a way to compare of the effectiveness of different designs of stators for alternators.Winding factor is the ratio of electromotive force (EMF) produced by a stator having a short-pitch, distributed, or skewed winding, with a stator having full-pitch, concentrated, and non-skewed, windings.
In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. [1] The armature windings conduct AC even on DC machines, due to the commutator action (which periodically reverses current direction) or due to electronic commutation, as in brushless DC motors.
