7.9 Service information transaxles
Summary
End of 2008 Handicare has published the product update "Trophy with S-Drive Controller". Among other things, this update
mentioned the new sturdier transaxles for Trophy with Egis controller and for Trophy with S-Drive controller. Since the benefi ts of
these new transaxles remained underexposed in the load of information in the news item, we will explain here the improvements
to the transaxle and summarise service instructions for these parts.
The new transaxles (Egis or S/Drive confi guration) offer improved bearing and bearing position. New, bigger motor brushes
also contribute to extend the life expectancy of the parts and reduces costs of ownership.
Regular preventative service checks are important to verify the condition of the parts and enables to replace them at the right
time. See service instructions.
Description
The new transaxles (standard and heavy duty / Egis and S-Drive compatible) as presented in our Product News item "Trophy
with S-Drive Controller" dated 10/09/2008 offer improved performance and life expectancy. This is due to the improved bearing
and bearing position but also to some changes that were made to reduce wear of the commutator and brushes. This way service
costs are reduced.
The new transaxles are equipped with bigger motor brushes. As a consequence the current density (Amps/mm2) in the
commutator and brushes drops and this improves the life span of these parts. The effect is more pronounced in the Trophy Egis
because this controller uses higher currents than the S-Drive controller.
Regular preventative service checks are important to verify the condition of the parts and enables to replace them at the right
time. Therefore see the service check instructions.
