A technical catalogue providing design criteria, electrical data, characteristic curves, type designations, and installation guidelines for Bosch automotive…
This document serves as a comprehensive guide to Bosch automotive alternators, detailing the specific design criteria required for different vehicle applications. It outlines how factors such as engine speed range, battery voltage, load power requirements, and environmental conditions influence alternator selection and development.
The catalogue provides extensive technical information including electrical data, physical dimensions, and characteristic performance curves. It explains type designation codes (e.g., GC, KC, NC) and defines key operational parameters like cutting-in speed, idle current, and maximum output speeds to assist in proper system matching.
| Rated voltage options | 14V/28V |
|---|---|
| Maximum speed for compact alternators | 18,000 ... 20,000 min–1 |
| Maximum speed for commercial vehicles | 8,000 ... 15,000 min–1 |
| Speed at rated current (nN) | 6000 min–1 |
Passenger car models include GC, KC, NC, G1, K1, and N1.
Commercial vehicle models include K1, N1, and T1.
It is the speed at which the alternator starts to deliver current when the speed is increased for the first time.
The main source of electrical interference in the Sl engine is the ignition system.
