The compulsator is used like a capacitor, to gather energy from a low-power source and store it, then generate a high-power output for a short period. The windings of a compulsator are different from those of a normal alternator in being designed for minimal inductance. This allows the current in the windings to change very rapidly, which is ...
The Seaslug missile alternator used a speed of 24,000 rpm to produce 1.5 kVA of electricity at 2,400 Hz. [6] The field may be supplied by either permanent magnets or by field coils. Regulation of the output voltage is achieved by controlling the current through a winding, either the field coil, or a control winding around a permanent magnet. [6]
Alternator (silver) mounted on a V8 engine Alternator voltage regulator (brushes are worn out) An alternator is a type of electric generator used in modern automobiles to charge the battery and to power the electrical system when its engine is running. Until the 1960s, automobiles used DC dynamo generators with commutators.
An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators. Large 50 or 60 Hz three-phase alternators in power plants generate most of the world's electric power, which is distributed by electric power grids. [4]
An Alexanderson alternator is a rotating machine, developed by Ernst Alexanderson beginning in 1904, for the generation of high-frequency alternating current for use as a radio transmitter. It was one of the first devices capable of generating the continuous radio waves needed for transmission of amplitude modulated (AM) signals by radio.
Six-cell lead-acid batteries produce around 12.6 volts while discharging, and their corresponding automotive alternators are designed to produce 13.5 to 14.5 volts during charging. [1] 42 volts is an approximation of the output of the new standard's charging system. [2]
