Web18 sep. 2024 · The Alternator "may-not" "Self-Excite" until it reaches around ~10,000-Rpm. This only has to occur 1 time, as long as the Alternator RPM is maintained above approximately ~2000-RPM, below that point, it may "drop-out" if it has a moderate Load on it. Some GM Alternators will self-excite at as low as ~5000-RPM, WebIn order to get your pulley ratio you would measure the diameter of your crankshaft pulley and divide it by the diameter of the alternator pulley you will be using. For example, if your crankshaft pulley is 6" in diameter and the alternator pulley is 2" in diameter, the ratio would be 3:1 or 6 2 = 3. The larger the ratio, the faster the ...

The minimum RPM of a 12 volts alternator is nearly 1800 RPM .
WebIn addition to the gear ratio issue, the alternator rotor is heavy and has to spin up to speed quickly, causing resistance to the drive belt. To compensate for the drive force required to get the alternator up to speed, car makers have had to use high tension forces on the drive belt. That increases belt and tensioner wear and reduces gas mileage.
Web18 nov. 2024 · Example: 700C x 50mm. Diameter = 622mm + (2 x 50mm) = 722mm. Circumference = 722mm x 3.1416 = 2268mm. Divide circumference by 25.4 to get inches then that number by 12 to get feet or 7.44 ft. With that you can calculate the speed for any RPM.
