addition to use in pure EVs, the iDM is
also suitable for P4 hybrid vehicles, for
which the technology is a secondary
drive unit. BorgWarner’s fully integrated
modules are seen as key enablers for
electrification and the development
of future solutions for global vehicle
manufacturers.
Multiple options
Operating at 230 to 450 volts of direct
current (VDC) the iDM is available in
three different peak power densities of
90kW, 120kW and 160kW at a nominal
level of 330VDC, with peak torque
outputs between 2,500Nm and 3,500Nm.
This flexibility provides a scalable and
modular architecture and a wide range
of gear ratios to meet varying customer
demands.
Smooth, powerful performance
Alongside advanced
transmission
technology based
on the company’s
eGearDrive system,
the iDM features
specially developed
integrated power
electronics,
which offer
full software
functionality,
with an option
of high-level
control of vehicle
dynamics and energy management.
Another core component of the iDM
is BorgWarner’s patented electric motor
technology, within which rectangular
windings in a hairpin configuration
are used instead of conventional round
wire windings. Besides power density
and efficiency improvements, the highvoltage
hairpin strategy also offers
considerable improvements regarding
space requirements. Compared to
round wires, hairpins require 20% less
room and have 10% less mass than
conventional motors with similar
performance features. Another key
feature of the iDM is that, with the
use of tools in the design, analysis and
testing processes, NVH performance
is optimised while still meeting other
performance targets.
With its integration of a state-ofthe
art transmission, electric motor and
power electronics, the iDM helps global
automakers in their quest to design
cleaner and more efficient vehicles. They
can rely on BorgWarner’s propulsion
solution, which is easy to fit, fully
tested and validated. The compact,
lightweight and highly efficient
iDM enables reduced energy
consumption for electric
vehicles, which results in
extended pure electric
driving range on a single
battery charge.

››Driven by mounting
sustainability demands as
well as emissions regulations,
automakers worldwide are being
challenged to develop increasingly
efficient propulsion solutions. In
line with this growing global trend,
manufacturers of cars and light
commercial vehicles are looking for
fully validated electric traction and
transmission systems to help them keep
pace with the evolution of vehicles.
BorgWarner’s fully integrated drive
module (iDM) for hybrid and pure
electric vehicles demonstrates the
company’s holistic approach to the
development of future solutions.
The advanced solution uses common
architecture and integrated power
electronics to offer OEMs simplified
design options for their primary and
secondary propulsion.
Improved efficiency with iDM
BorgWarner’s latest drive module
solution is an eAxle unit that combines
transmission technology and an electric
motor, as well as highly efficient power
electronics, in a compact integrated
design offering higher efficiency and
lower weight. EVs fitted with this
module consume less energy, allowing
OEMs to optimise battery size and
pure electric driving range on a single
battery charge. The advanced all-in-one
solution is easy to integrate, either
at the front or rear axle of passenger
cars and light commercial vehicles. In
