McLaren SMART G-type Alternator 140A
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.
Output voltage 14.3V DC default, configurable over range 11V to 16V DC
Nominal output current at 10,000 RPM at 13.3V, see performance chart
