INDUSTRY NEWS
alter the damping rates of the shocks almost instantly. By adjusting
the damping rate, the car can better respond to varying road
surfaces or sharp turns by maximizing tire contact on the road for
greater driving precision.
Debuting on the 2020 CT5-V and CT4-V, and expanding to the
2021 CT5 Sport and all-new Escalade, nearly every aspect of
the previous system was reevaluated for the development of
MagneRide 4.0. This includes the sensors, controller hardware,
dampers and vehicle tuning methods. Among the improvements
are:
*
New wheel hub accelerometers and an inertial measurement
unit transmit and process changes in road conditions
four times faster than the previous system, for more fluid and
natural-feeling damping changes.
*
performance driving.
*
New secondary temperature maps enable engineers
to compensate for changes in damper fluid temperature, which
contributes to more consistent performance, especially during
New magnetic flux control creates a more consistent
and more accurate transition between rebound and compression
in the dampers, improving the system's ability to sense and
control vehicle body movement.
*
A significant reduction in damper friction produces a
near " no damping " effect that enables engineers to tune for more
pronounced differences between drive modes.
*
A new magnetorheological fluid formula reduces friction
within the damper that contributes to smoother overall damping.
BWI Group manufactures brake and suspension systems for the
global transportation market, among them its exclusive MagneRide
system. In 2019, it opened a new plant in Indiana, its first
in the USA and second in North America, as previously reported
in Magnetics Magazine. For more info, see www.gm.com, www.

Bender Current Transformer Designed for EV
Charging
Bender, a global manufacturer
of electrical safety products, has
introduced a new current transformer
optimized for charging
electric vehicles. The compact
CTBC17 is designed for use in
e-mobility infrastructure and AC
charging stations to monitor leakage
currents in mode three electric vehicle charging.
It features an integrated magnetic field shielding to prevent interferences
from external magnetic fields and can be configured for
PCB mount or cable harness connection. Internal diameter is 17
mm, making the transformer suitable for the use of supply lines
with a large conductor cross section.
Headquartered in Gruenberg north of Frankfurt in central Germany,
Bender GmbH employs 1,100 people at operations in 15
countries serving numerous industrial and medical applications.
