BorgWarner’s “iDM” Solution Takes Electric Propulsion to a New Level
BorgWarner (BW) has been putting great efforts
in development of its drive modules. These innovative products make a
significant contribution to further development of future pure electric drives.
Recently, BW presented its new integrated drive module (iDM).
The new solution is considered to be a step
forward, after the electric drive module (eDM) (predecessor of iDM) has been in
mass production for some time.

The product line includes 3 different
modifications (
iDM XS, iDM S, iDM M) and is easy to install either at the
forward or the back axle of passenger cars and light-duty trucks. These
solutions can be applied not only in e-vehicles, but also can be easily used in
P4 hybrid vehicles, where the motor is positioned at the back axle of the FWD vehicle.
The design of this drive unit is notable for usage of high-capacity power electronics
combined with the sophisticated transmission system and innovative e-motor
featuring BW’s efficient bar wound stator to compose a space-saving propulsion
system.

Thanks to the iDM solution, BW can strengthen its market positions by providing innovative propulsion solutions for hybrid and electric vehicles. BW representatives express confidence that the company’s contribution to development of environmentally oriented solutions will find broad application in the automobile industry. The power electronics implemented in the iDM ensures relative design simplicity and minimum losses. Moreover, it provides a wide range of software features with an option for the high-level control of car dynamics and energy management.
The software design complies with existing market standards and can be adjusted to typical platforms like AUTOSAR and to risk classification scheme ASIL D. To process the growing amount of data exchange within sophisticated car units, BW’s advanced power electronics can be integrated with a CAN or a CAN FD bus. In principle, the main advantages of the iDM include its scaling and modular structure and a variety of gear ratios, as well as different e-motor options. Thus, the iDM solution can satisfy demands of picky customers. The iDM has superior torque and power density rates.
The sophisticated transmission solution ensures enhanced performance characteristics. All elements implemented in the iDM unit became an essential part of BW’s portfolio of mature technologies which can be also used separately. BW constantly works on development of innovative products and gains more prestige among global OEMs.
