Alternator K-Type and SMART

< Back

K-Type

The K-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.

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°


Hard-wire back-up of the regulator is also available if requested.

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

* If alternator is continuously connected to the battery this quiescent current draw may drain the battery

Connection definition

  • 22AWG cable (where fitted)
  • Cable length is shown on the order details but any length is available on request
  • Various automotive and military standard connectors are available
  • Positive power output M8 stud (B+ terminal)
  • Ground connection for power and regulator is through the case. Ensure that the case has a high current, low resistance connection to vehicle ground.
