SMART Alternator G-Type Alternator with CAN Communications

This 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 and is configurable over the CAN interface. 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 18,000rpm).  The standard mounting method is intended for a belt drive, but the alternator may also be driven directly, if required.

CAN Communications Interface

  • Voltage set point configuration
  • On/Off control
  • Diagnostic information, including:
    • Regulator and Rectifier Temperatures
    • Output Voltage Measurement
    • Over-Current Warning
    • RPM measurement 

Connection Definition

  • 22AWG un-screened cable
  • Viton jacketed cable
    • 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
    • Cable Connection

      Pin 1              Green wire                 Ignition

      Pin 2              Red wire                    Sense

      Pin 3              White wire                  Lamp
