Any device that generates an electrical current is a generator. "Generator" is a generic term. A photovoltaic solar panel is a generator and it produces DC. All practical electromechanical rotating machines generate AC. The "generator" in a 1951 six volt De Soto is actually a dynamo, that's not an out of date old fashioned term. It generates AC power that is rectified by the commutator and brushes that are internally timed like the valves in an engine. Each time the magnetic field reverses, the commutator reverses the electrical connection for that pole piece. So the dynamo doesn't generate DC, it rectifies the AC it's generating. No modern portable generator has a dynamo in it. Regardless of size they all have alternators. The generators in utility grid power plants are three phase alternators. The alternator in your motorcycle, outboard motor and electric start lawn mower are permanent magnet alternators. The magnets (rotor) are the field. Automotive alternators have no magnets. They use battery excited electromagnetic fields (rotor), fed through small brushes riding on slip rings, which are fed by the voltage regulation circuit. This article missed the most important point of all, silicon semiconductor diode rectifiers. This technology is the reason we don't use dynamos in motor vehicles, small engines or portable generators anymore. Diodes rectify the AC to DC to charge batteries. Automotive alternators are three phase, needing six diodes in a three phase bridge to fully rectify the three phase current they generate. Typically small engine permanent magnetic alternators are single phase requiring four diodes in a full wave bridge rectifier, although there are three phase PM alternators requiring six. The reason dynamos didn't produce enough power at low RPM was because of the brushes and commutator. The brushes are a pair of big carbon resistors in series with the load. Diode rectifiers are much more efficient and never wear out.

Hi. I owned several British motorcycles from the '50's which had Joe Lucas's 60 watt DC commutated generators. These were married to a cut-out and voltage control box (in an on-again off-again relationship) that gave feedback to the generator's field coils. Voltage control was by vibrating points, energized by electromagnets fighting a spring, the tension of which was adjustable so the voltage output of the armature could be adjusted to the 7.3 or 14.7 volts needed to charge the battery. The unreliability of the system was directly proportional to the number of times you read this paragraph. There was an amp meter on the headlight nacelle. When kicking the bike to life, a huge surge of relief accompanied the amp meter's first twitch that showed the electrics were working today. We motorcyclists traveled in groups, not because we wanted to scare the living daylights out of the locals, but because it was the only way that a few of us would have lights to drive at night. Joseph Lucas was affectionately known as "The Prince of Darkness". Ah, those were the days, but the nights weren't so good. Cheers, P.R.

Generator is the umbrella term. This includes alternators and DC power generators, like those found in the old VW Beetle. 5:37 The rectifier doesn't regulate anything. The rectifier converts AC to DC. The voltage is regulated via the built-in regulator and the field windings. 6:27 In power plants, the voltage is also regulated via the field windings. It's not just the frequency, i.e. speed, that has to be constant. Also the voltage.
@ralfbaechle29 күн бұрын
In slightly older power plants the frequency is mechanically controlled via the turbine. Once the generator is synchronized and subsequently connected to the grid one could argue that the power grid is controlling the frequency of the generator as the influence of a national grid hooked up to the generator via a high voltage line is stronger than the puny influence of the turbine regulator. At that point opening up the regulator of one generator will only marginally (mHz if that much) influence the frequency of the generator and grid but mostly influence the current being "pumped" into the grid.

I'm from the old school. Generators produce DC power through the commutator; alternators produce AC power through slip rings. The video shows a good explantion of the difference. During the video, the narrator uses the term "generator" to refer to both types of power generation. That push mower uses neither so it shouldn't be in the video. One advantage of a DC generator is that it can be used as a starter motor in small engines until the engine is running. Then it can produce DC power for the needs of motor. Gas golf carts use this method for one.

AC is NOT produced thru the slip rings, the AC is produced in the stator and the stator is connected to the rectifiers to produce the DC for the vehicle. Slip rings feed a DC voltage to produce the field or excitation, field current from the regulator controls the output via a sense line. Newer ones use PWM and ECM control.

Why is there no mention of a 'Dynamo'? In use in cars, dynamos generate DC (interrupted) to charge batteries directly. They were replaced with Alternators on cars, only when solid state rectifiers became available (to turn the three phase AC immediately to DC). Alternators then became the default generators of car electrical system, because they can output more power and turn at a faster speed. The commutator of a dynamo, limited it's turning speed and so, at low revs could not produce much power. I found this video uneccessarily, misleading and contradictory. Alternators produce A/C. Dynamos produce D/C and the term geerator encompasses anything that produces electricty by mechanical means. Simple.

Some lawn mowers do have “generators”, some electric start lawn mowers proved a small changing voltage to maintain the charge on the battery (some don’t provide a charging voltage, the owner has to periodically connect a charger which is kind of dumb in my opinion.) The charging circuit for the lawn mower battery is very basic, just a separate coil that picks up the magnetic field primarily intended for the ignition magneto, a single diode provides half-wave rectification (only allows the positive part of the alternating current to pass) and blocks the battery voltage from discharging through the coil. It is very inefficient (cheap) and completely unregulated, typically the batteries don’t last more than one or 2 seasons because the a constantly being overcharged.
@brianperkins612125 күн бұрын
If the lawn mower has a battery operated starting system it is an option to include a charging coil or more correctly a stator , as the flywheel with its integrated magnets spin past the coils of wire within the stator, an Alternating Ac current is produced in proportion to the speed of the engine , because the intension is to charge a Battery this must be put through a rectifier turining the output in DC current this device also contains a regulator to prevent overvoltage at high rpm as well as regulate the charging process, in this case the regulator ususly shrunts the excess currrnt through a series of resistors to control the charging currrent and voltage supplyed to the battery. some newer regulators use transistors to regulate the volatge coming from the stator as the AC sine wave goes through them they cut of the top of the sinewave to hold the voltage below a given level this has the avantage of not producing so much heat. I have seen a few very cheap few systems that simply have such a small stator that is put through a half wave retifier that produce such low charging currents (under a half an amp) that they exclude the regulator kzbin.info/www/bejne/fpXMappsq5qnaLM

AC generators like those at power plants do not have a commutator, they may have slip rings like an automotive alternator has, but those would be for excitation current like in an automotive alternator. Only DC dynamos have a commutator and that is because all electromagnetic based generators (everything other than a solar cell, battery, etc.) generate AC power, the commutator switches the polarity of the AC so that it becomes a pulsed DC current, doing the same job as the diode pack on a car alternator but with a mechanical device instead. Gas generators probably use an alternator-type design so they can omit strong magnets and use an excitation current instead which also allows for cheaper power regulation without as much need for complex and expensive solid state parts like a LARGE buck boost DC-DC converter or a more complex design for the inverter... and a simple design can be achieved with an AC generator designed like a car alternator by hooking it directly to the plugs and holding the motor at a constant RPM so that the waveform is roughly a 60Hz sine wave. This video is slightly misinformed. Most generators today are alternators, just a LOT bigger and often more efficient than a car alternator.

Read answer from @majed9r! Alternators have brushes and slip rings to maintain the magnetic field in the rotor. As the speed of a motor is changing and the power needed for the equipment (headlights, stereo etc.) is constantly changing, one current regulator is needed to maintain the constant voltage between 13.7 to 14.5 volts to fill the battery. This regulator regulates the current through the slip rings. The output is 3 phase AC those who are rectified to DC. And to be precise: every machine that generates (converts) one type of energy to the other is generator. The usually term generator is used for the conversion to electrical energy, usually mechanical energy. (Solar generators? Convert Sun energy to electrical).

This was the most bull I've ever heard. Most small portable generators work just like the alternator in your car. The main difference is that in a true generator the power id feed through the brushes. In an alternator the field is powered through the brushes. The fact that the generator has the power going through the brushes and that if DC is desired, this is done through a segmented commutator. This was done because high current diodes were not yet invented. Both can be used to create AC or DC outputs but the rotating field winding makes more sense with solid state regulation. The old DC generator used in old cars use a regulator that controlled the output that wasn't solid state. It used a relay like device that measured the strength of the magnetic field and changed the field current by chopping the current to the field winding. The small portable generators use the rotating field windings. ( smaller that 10KW typical ) larger generation usually uses fixed field windings because the cost of the higher current in the external windings needs to be larger, as compared to the smaller amount of copper needed for the field. It is true that brushes that carry higher current through a commutator have more arcing and wear faster. Still, the brushes in alternators do wear. In my experience warn out brushes are the most common failure of car alternators that are no abused. Bushes are cheap compared to the complete alternator but shops have different warranty than a home mechanic ( 1/10th ). When someone tells me, that their alternator just died, the first question I ask, is did they jump start another car within the last month or so? If so, that was likely the cause. The older generators can take sudden high current loads required for starter motors and can take more abuse. The diodes in alternators can be damaged by such sudden high current loads. When I jump start, I ask for the other car's keys. I charge their battery for a while with my engine then shut my engine off and give them back their keys to try to start. I do use home made cables with 00 wire. I can even start a car without a battery with my cables. Never use your alternator to power a starter! Even if it seems to work for a few weeks, the high current through the diodes can rupture the hermetic seal. Moisture and other contamination will cause the diode to fail being a diode.
