Why are alternators used instead of generators in cars?
Why are alternators used instead of generators in cars?
In the last two decades alternators have replaced generators in motor vehicles. The reasons are many: output current can be produced at lower rpm, voltage can be more accurately’ controlled with solid state regulators, alternators need less maintenance, and they cost less to manufacture.
Do you need an alternator to charge the battery?
We should now have the engine running, so it is time to get the battery charging. To do this we need to connect the alternator. Unless one has a very basic boat where the charging system is only used to charge an engine battery for the next start a dynamo is not really up to the job.
How does a moving coil in an alternator work?
In the alternator, however, the moving coil, called the rotor, uses current supplied through slip rings to generate a moving field. Power is extracted from the stationary field coils. Slip rings replace the weak generator commutator.
Is it safe to disconnect an alternator while the engine is running?
It is probably safest to assume that any particular alternator is not fitted with one, so never disconnect the alternator, battery, or switch a master switch whilst the engine is running – you have been warned. Occasionally the surge quench diode (when fitted) works, but destroys itself in so doing.
Who are the makers of high output alternators?
High Output Alternators manufactured in the USA by ZENA, Incorporated High Output Alternators — so tough, and so powerful, that we weld with them! The ZENA ® mobile welding system is a new technology, self-contained, ultra-compact, commercial duty, engine-driven welder which can be attached to any engine.
How to troubleshoot an alternator and charging system problem?
If necessary, adjust the belt with the help of your car owner’s manual or repair manual. Inspect the belt for signs of cracks, cuts, shiny spots, deterioration or other signs of wear or damage. Change the belt and belt tensioner at the manufacturer’s recommended interval. 2. Check for Wiring Problems
Can a welder use a high output alternator?
High Output Alternators — so tough, and so powerful, that we weld with them! The ZENA ® mobile welding system is a new technology, self-contained, ultra-compact, commercial duty, engine-driven welder which can be attached to any engine.
How does an alternator work in a car?
First, the alternator in a car is designed to keep a healthy battery fully charged. It is not designed to recharge a dead battery. Second, car batteries are what are called “starting batteries.” They are designed to deliver short bursts of power to spin the starter motor, and then to be continuously recharged by the alternator.
