Alternator Voltage Regulator
Alternator Voltage Regulator -
One way of fullfielding an alternator with an integral voltage regulator is shown on the GM alternator in Figure 35.3. A screwdriver is used to short a tab on the frame to ground. On some alternators with an external regulator, fullfielding is done 9.2.1 Voltage Control of ac Generators The voltage of ac generators is controlled by voltage regulators working on is cut in and cut out on the exciter field circuit, depending on the alternator voltage variation so as to maintain it constant.VOLTAGE REGULATOR 2 ~ RESISToR WINPNG \b L' FIELD DIODEs BATT ALTERNATOR IGN REG BATT G) GB) 4. BATTERY are regulated at a preset level. inside the alternator and surround the rotor. As the rotor turns, its magnetic field regulator winding.
When.a predetermined value of the voltage is attained, the regulator armature is pulled down, opening the lower contact points. Tht resistance is inserted into the field circuit of the alternator, resulting in reduction of field Electronic regulators are nonadjustable. Some older vehicles have electronic regulators mounted externally from the alternator. DaimlerChrysler vehicles manufactured since 1 985 have the voltage regulator designed into the PCM.
