automotive alternator

Automotive alternator: test performance over the wide range of conditions experienced in practice; show the need for circuit protection.

Automotive alternators are usually belt driven at 2-3 times crankshaft speed.

He came up with what eventually became the first commercial car radio and helped to develop the first automotive alternator that could be mass produced.

A specially adapted automotive alternator provides low cost, DC output.

These motor/generators have considerably more powerful electronic devices for their control than the automotive alternator described above.

Most battery-based systems use an automotive alternator.

One such project examines the suitability of such a machine as a low cost compact and efficient automotive alternator.

Many small systems use automotive alternators producing 12 VDC, and possibly charging a battery.

Wonder Auto was ranked second in sales revenue in the China market for automotive alternator and starter in 2006.

Marine alternators used in yachts are similar to automotive alternators, with appropriate adaptations to the salt-water environment.

Wonder Auto is expected to supply approximately 800,000 automotive alternators to a Shanghai-registered international auto parts procurement center over the next three years.

Automotive alternators require a voltage regulator which operates by modulating the small field current to produce a constant voltage at the battery terminals.

Most automotive alternators generate three phase AC and rectify it to DC with a diode bridge.

Automotive alternators use a rotor winding which allows control of the alternator's generated voltage by varying the current in the rotor field winding.

Automotive alternators are a common example, where the diode, which rectifies the AC into DC, provides better performance than the commutator or earlier, dynamo.

Lead-acid batteries produce around 12.6 volts while discharging, while automotive alternators produce 13.5 to 14.5 volts during normal charging operation.

Efficiency of automotive alternators is limited by fan cooling loss, bearing loss, iron loss, copper loss, and the voltage drop in the diode bridges.

On January 29, 1988 Motorola sold its Arcade, New York facility and automotive alternators, electromechanical speedometers and tachometers products to Prestolite Electric.

Wonder Auto acquired the remaining 79.6% of Jinzhou Wanyou in April 2007 thereby expanding the Company's product mix by adding shock absorber rods, vibration dampers and rotary axles for automotive alternators and starters.

Hydrogen fuel enhancement from electrolysis (utilizing automotive alternators) has been promoted for use with gasoline-powered and diesel trucks, although electrolysis-based designs have repeatedly failed efficiency tests and contradict widely accepted laws of thermodynamics (i.e. conservation of energy).

By mounting this motor generator unit in the conventional location traditionally used for the standard automotive alternator, it permits a low-cost method of adding mild hybrid capabilities such as start-stop, power assist, and mild levels of regenerative braking.

Founded and owned by Vincent Trapani, U.S.A Industries says it has become "one of the nation's largest remanufacturers of automotive alternators, starters, axles and disc brake calipers" by stressing quality, prompt delivery and competitive prices.

Not only did Mr. Wavering make spending time in the car more pleasurable, but in the 1950's he and a team of engineers at Motorola developed the first automotive alternator that could be mass produced, helping to make cars more comfortable and easier handling.
