ALTERNATOR OVERVIEW

The alternator is made up with the following major components;
1. Brush holder assembly
2. Rear bearing carrier
3. 2 pole rotor (all copper wire)
4. Stator assembly (all copper wire)
5. Engine adaptor

ROTOR ASSEMBLY

The alternator has a 2-pole rotor, which means the rotor has
a single south magnetic pole and a single north magnetic
pole. As the rotor spins, its magnetic field passes through the
stator assembly windings and voltage is induced into the stator
windings. This is known as induction. The rotor shaft has a
negative (-) slip ring and a positive (+) slip ring, with the negative
(-) nearest the bearing carrier. The rotor shaft is held in place
with single through bolt.

STATOR ASSEMBLY

The stator houses, AC power windings and excitation windings.
It is held in place with 4 bolts that pass through the bearing
carrier and engine adaptor, then attached to the engine mounting
flange. In combination with the rotor assembly, they generate the
electrical out-put of the HSB.

BRUSH HOLDER AND BRUSHES

The brush holder is a component that holds the brushes in a
stationary position enabling them to maintain contact with the
rotating surface commutator rings on the rotor. The brush holder
is attached to the rear bearing carrier by means of a M5 x 20
bolt and a location tab. A negative (-) brush and a positive (+)
brush are retained in the brush holder. The negative (-) brush
rides on the slip ring nearest the bearing carrier. The brushes are
spring loaded to maintain contact.
A RED wire connects to the positive (+) brush and a BLACK
wire to the negative (-) brush. Rectified and regulated excitation
current, as well as current from the field boost circuit, are
delivered to the rotor windings via the RED wire, and the positive
(+) brush and slip ring. The excitation and field boost current
passes through the windings and to the frame ground via the
negative (-) slip ring and brush, and the BLACK wire.

SPECIFICATIONS
The current flow creates a magnetic field around the rotor having
a flux concentration that is proportional to the amount of current
flow.
