Title: Automotive alternator
Inventor: ASAO YOSHIHITO
IPC: H02K3/12
Filed: 2002-01-11
Abstract: PURPOSE: To obtain an alternator for a vehicle capable of suppressing temperature rise. CONSTITUTION: Since a ratio (bt/ht) of a width bt and a length ht in a radial direction of the teeth 42 of a stator iron core 41 is made 0.15<bt/ht<0.4, a narrow ventilation path 100 is formed. Then, since cooling air by a cooling fan vents through the narrow ventilation path 100, the speed of the cooling air is increased, and heat generated by a stator coil 16 is efficiently radiated into the cooling air. As a result, the temperature rise of the stator 40 is suppressed. As the temperature rise of the stator is suppressed, the output is also improved. Further, even under the worst operating condition, heat deterioration caused by softening of vanish is suppressed, and a damage to an insulating coat caused by the friction between the wire of the stator coil 16 and the stator iron core 41 is also suppressed. Hence, the electric insulation quality is enhanced.
