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 ...
ACDelco is an American automotive parts brand owned by General Motors (manufactured by GM are consolidated under the ACDelco brand, which also offers aftermarket parts for non-GM vehicles. Over its long history it has been known by various names such as United Motors Corporation , United Motors Service , and United Delco .
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]
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 low current and relatively smooth slip rings ensure greater reliability and longer life than that obtained by a DC generator with ...
The main alternator is the larger of the two sections, and the smaller one is the exciter. The exciter has stationary field coils and a rotating armature (power coils). The main alternator uses the opposite configuration with a rotating field and stationary armature. A bridge rectifier, called the rotating rectifier assembly, is mounted on the ...
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.
