An alternator for generating electrical power to one or more components of a power network includes a machine portion including a stator, a rotor and a rectifier, a battery connection terminal connected to the machine portion and configured to be connected to a battery, and an isolation device integral to the alternator. The isolation device is located on an electrical path between at least the machine portion and the battery connection terminal, and the isolation device is configured to isolate at least one of the alternator and another component of the power network from receiving electric current from the battery based on an undesirable condition occurring in the power network.

Electrical isolation of an alternator

An electric machine for a vehicle comprises a housing, a rotor shaft, a first fan member, and a second fan member. The housing includes a first end portion having at least one air inlet opening and an opposite second end portion having at least one air outlet opening. The rotor shaft extends through at least one of the first end portion and the second end portion and is configured to rotate relative to the housing. The first fan member is located within the housing and is mounted on the rotor shaft. The second fan member is located outside of the housing and is mounted on the rotor shaft. Rotation of the rotor shaft causes each of the first and second fan members to generate an airflow from the at least one air inlet opening to the at least one air outlet opening.
