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

WARNING
The HSB weighs more than 500 lbs. (227 kg).
Use the aid of additional assistants and exercise caution during
installation.
Inspect the generator for damaged or loose parts. DO NOT operate
the generator if any components are damaged or loose. Contact
your dealer for assistance.
1. Cut banding straps.
2. Remove top lid.
3. Remove center cardboard supporting rib.
4. Lift cardboard housing and set aside with all other trash.
5. Remove plastic covering and discard.
6. Remove 4 securing clamps. Save if going to use anchor bolts
to secure to concrete pad (not supplied).
7. Insert 2 lifting rods (not supplied) into lifting notches at each
end of the base.
8. Discard all shipping materials and recycle if possible.
NOTICE
–
If you know length of run for wires you may want to install
the ATS communication wires and voltage wires now
before setting unit to industry 1st 17.7 in. from fire rated
wall and when code permits. Install the wires, some of the
gas delivery pipes and flex hose now while you have ample
room and at tailgate height is much easier than when in
place
