Using an overrunning pulley, the alternator can continue to keep spinning at a substantial speed once the motor slows down. The engine will drive the alternator, but in the event the motor slows down the alternator will not be forced to decelerate with it.

Alternators used in central electrical power stations also control the sector present-day to control reactive electric power and to assist stabilize the facility method versus the effects of momentary faults.

The more recent cars have alternators which might be "temperature compensated". This implies they demand at diverse voltages depending on the temperature. A warm battery involves much less voltage to demand than a chilly battery, so the temperature compensated alternators demand in a decrease voltage when hot than when chilly.
