What are the causes of a car alternator not generating electricity?

[Cayden]

There are several reasons why a car alternator may fail to generate electricity: 1. The alternator does not operate within the specified technical conditions: such as high stator voltage, increased iron loss, excessive load current, and increased copper loss in the stator winding; 2. Low frequency: which slows down the cooling fan speed, affecting the alternator's heat dissipation, and a low power factor increases the rotor excitation current, leading to rotor overheating; 3. It is necessary to check whether the monitoring instruments indicate normal operation: if not, necessary adjustments and treatments should be made to ensure the alternator operates according to the required technical conditions.
