PRODUCT NEWS
and other debris. Originally geared toward off-road applications,
the air-cooled 55SI has recently been improved to better survive
the difficult, corrosive environment encountered in transit applications where durability and high output are essential.
"While no physical magnets are utilized in it, the alternator does
rely heavily upon mechanical physics and electromagnetic
principles to generate the necessary power for the vehicle electrical system," according to Rob Steele technical product lead for
alternator engineering at BorgWarner in Noblesville, IN.
read distance of 1.3 mm.
In March, the company introduced two versions of its absolute
magnetic linear encoders with Siemens Drive-Cliq interface
designed for plug-and-play installation into Siemens motion controller environments. Plug-and-play installation makes incorporating them into the drive system easy. The controller automatically
detects the sensor and its basic settings.
Since leaving and returning to the detection range of the
magnetic tape is permitted, the encoders provide a simple and
economical solution for demanding applications in the fields of
automation and machine tool building including retrofit applications.
Based in Neuhausen, Germany, near Stuttgart, Balluff manufactures a broad array of automation products including many
magnetic solutions such as magnetorestrictive linear position
sensors, magnetic linear and rotary encoders, inductive sensors
and magnetic field sensors.

Delco Remy Alternator Designed with Power
for Commercial Transit Vehicles

"Our commercial vehicle alternators are based upon the Lundell machine design consisting of a field coil controlled by the
integrated regulator that generates the magnetic field that is
induced into the stator when rotating. The generated AC voltage
is converted to a usable DC voltage by the rectifier bridge."
"Traditionally, transit applications have used alternators that are
so heavy they require a mechanical lift to install. Plus, they take
up a lot of space and are limited on where they can be installed,"
explains Steele. "The 55SI, which I like to refer to as the big
brother to our popular 40SI, is smaller and more lightweight than
what's traditionally been used in this power range. This allows
it to be installed by one person. Additionally, it can be used in a
single or dual alternator application." As a brushless heavy-duty
alternator, it is one of the highest output air-cooled machines on
the market with 33% more output than any other alternator in its
class, noted Steele.

Today's mega and charter buses and other commercial transit
applications are outfitted with lots of door operation, lighting, AC
and other electrical-based amenities. While these ensure a comfortable user experience, they also put a demand on the system
and require an alternator that's up to the job.
