F-Type Alternator 90Amps

The F 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.

In Detail

Electrical

  • Output voltage 13.5V DC
  • Nominal output current
  • High 110A (cut in speed 3200rpm)
    Medium 90A (cut in speed 2400rpm)
    Standard 60A (cut in speed 1700rpm)

A detailed performance chart is shown later in this document.

Mechanical

  • Aluminium alloy body
  • Maximum speed 18,000rpm
  • Clockwise rotation
  • Weight  <2.9kg  F-type
  • Potted elastomer boot for strain relief of cable (where fitted) 

For high vibration installations, the strapped F type is recommended.  The rectifier is strapped to provide improved mechanical support 

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

  • 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
  • Ground connection for power and regulator is through the case. Ensure that the case has a high current, low resistance connection to vehicle ground.
  • Cable connection
  • Green wire Pin A Pin 1 Ignition
    Red wire Pin B Pin 2 Sense
    White wire Pin C Pin 3 Lamp
  • Connections for the integral connector (where fitted) are shown on the drawings

Environmental

  • Splash resistant to standard motorsport fluids
  • Viton jacketed cable
  • Continuous ambient operating temperature -30 to +90°C
  • Maximum ambient temperature 110°C short term, providing the following temperatures are not exceeded:
