Automotive alternator

Abstract

The automotive alternator according to the present invention includes: a case; a rotor that is disposed inside the case and that is fixed to a shaft; a stator that is disposed so as to surround the rotor and in which alternating current arises by means of a rotating magnetic field from the rotor; a rectifier that is disposed at an end portion of the shaft and that rectifies the alternating current that arises in the stator into direct current; and a noise preventing capacitor that is connected between a positive side and a negative side of the rectifier and that absorbs noise that arises during rectification into direct current by the rectifier, wherein a carbon resistor that suppresses current that flows to the noise preventing capacitor is connected to the noise preventing capacitor in series.
