yung standard alternator ng sasakyan kapag binago yung regulator at kelangang may standby na battery pwede din yun magoutput kahit mabagal lang ang ikot
damihan mo ang turns sa stator winding at gamitin lng ung maliit na magnet wire.
since the rotor is energized by a dc source (battery) via slip ring at the shaft,more turns in stator winding = higher voltage outputmore speed (rpm) = higher voltage outputhttp://homepower.com/article/?file=HP113_pg10_ATE_5If you use a car alternator in a wind turbine, the speed problem can be addressed in one of several unsatisfactory ways: * Use a small blade area so that the short blades can spin at high rpm. This means that you cannot catch much wind, and even so, you will need a high wind speed to get the necessary rpm. It will also take a lot of wind to produce high enough power to excite the magnetic field and actually have energy to spare. * Use gearing to increase the rpm. This involves extra cost, extra losses, extra unreliability, and overall ugly and clumsy engineering. * Rewind the coils to work at lower speed. This means more turns of thinner wire in each coil. This reduces the cut-in rpm, but also increases the losses in the coils themselves, limiting the power output and further reducing the already low efficiency.
Kunin natin ang hub ng bike. may shaft yun. fix the housing to a bracket. ang iikot ay ang shaft. One one side, ikabit ng blades. Sa kabila bolt on a chopping board na circular. Dun nkaglue ang mga magnets. Tapat ang magnets is the field coil.Mas mdali gamitin ng radiator fan motor. Extend the blades or attached to a vertical turbine The coupling is this way: leave the orig na blade pero with the wings(blads) removed at ma iwan and circular center. Bore 2 holes dun. yung shaft whether vertical of horizontal, may fork to inset into the holes.BK
the rotor's field coil is energized by a battery connected to the slip ring of the shaft. kung mahina na ang battery, mahina din ang magnetic flux generated by the rotor.ang voltage output depende yan sa flux cut by the stator coil and the rpm of the rotor.
ibig bang sabihin ay linear ang regulator na nakakabit sa car alternator?
kung ang dc output ng battery fluctuating, fluctuating din ang flux ng rotor.
di mo sir sinagot ang tanong ko, btw, ang regulator ng car alternator ay maihahalintulad sa isang self oscillating flyback na SMPS kung saan yung direct na source ay ipinapasok sa field/rotor
alternating current ang nasa flyback...direct current ang nasa rotor... supplied by the battery. Hindi fluctuating ang current galing sa battery. Bakit my regulator pa?
"bakit may regulator pa?" tataas ang output ng upto 50V(12V car alternator) kapag pinasukan mo ng unswitched DC supply yung field/stator, ang regulator ng car alternator ay simpleng comparator lang naman, may supply yung field/stator hangga't sa umabot ng 13.8V(12V car alternator) yung output then saka iswitch off yung supply ng field/stator
