G Type Alternator

ALTERNATOR

G TYPE up to 100 Amps

The G type alternator has a specially wound stator to achieve high power output in a small, low weight package. High current diodes are used in the rectifier and internal fans provide forced air cooling. The output is controlled by a regulator inside the alternator. The units are assembled with stiff brush springs and extra flexible wire to connect the stator to the rectifier. The stator is pegged to the body and all screws are locked. High quality bearings are used to enable the alternators to run at high speeds (up to 18,000 rpm). The standard mounting method is intended for a belt drive, but the alternator may also be driven directly, if required.

Please request our installation datasheet for further details.

Design and manufacture is in-house, so if our existing designs do not suit your application, we can provide cost effective customised parts to suit even the most demanding application.

For example:

· Through bored mounting holes

· High accuracy machining of mounting flanges

· Alternative cable entry locations

· Alternative connectors

· The regulator/rectifier unit may be rotated through 90°, 180° or 270°

Please contact our technical consultancy service who will be pleased to help.

Connection Definition
