Briefly, high output "popular" small frame alternators have a high rate of
failure due to higher heat
temperatures typically caused by; 1) continuous higher rate charging, 2) lack
of heat dissipation through
rectifier heat sinks & diodes, 3) insufficient cooling (air exchange/air flow)
through alternator and
components, 4) the "plugging up" of alternator by foreign matter such as
chaff, dust etc...as is common
in agricultural, mining and industrial applications and therefore limiting
cooling causing "burn out".
The invention consists of an improved alternator CE housing to allow for a
larger rectifier with larger
heat sinks (and thus its exposed surface area) and 9 50amp diodes vs. the
original 6 25amp diodes (and
thus increasing its current carrying capability) as well as an improved more
open design
in the housing and rectifier to allow for more air flow and a cooler running,
more durable alternator.
