Integrated Drive Module Order Confirmed for 2027 Production
Automotive component supplier BorgWarner has announced it has secured an order for its integrated drive module (iDM) from a global automaker, with production scheduled to begin in 2027. This collaboration will introduce the company’s latest generation of electric drive technology into the global electric vehicle market, further strengthening its position in the electric powertrain sector.
Coaxial Three-in-One Design Enhances Vehicle Packaging Flexibility
BorgWarner’s iDM integrates the electric motor, gearbox, and inverter into a single module, adopting a coaxial three-in-one design where the motor and output shafts are aligned on the same axis. This design replaces the traditional parallel offset layout, significantly improving the flexibility of internal vehicle space configuration and providing automakers with greater adjustability during electric vehicle platform development. BorgWarner states that this design optimizes the vehicle’s overall structure and enhances the integration efficiency of the powertrain system.
The iDM’s electric motor employs oil cooling technology, where the dielectric cooling oil directly contacts the motor windings and end-turns. Compared to conventional water-cooling systems, this method more effectively reduces motor temperature. The cooling approach not only improves motor stability under high loads but also extends the motor’s lifespan, making it suitable for various high-performance electric vehicle applications.
Fourth-Generation Inverter with Viper D Power Switch Boosts System Efficiency
The iDM’s built-in fourth-generation inverter (GenIV inverter) utilizes BorgWarner’s newly developed Viper D power switch. BorgWarner highlights that the Viper D reduces switching losses and increases current-carrying capacity, thereby enhancing the overall efficiency of the electric drive system. The reduction in switching losses not only lowers the inverter’s heat generation but also eases the cooling system’s burden, allowing battery energy to be more effectively delivered to the wheels and improving the vehicle’s energy utilization efficiency.
BorgWarner has previously applied Viper series power switches in 800-volt silicon carbide inverters, successfully deploying them in plug-in hybrid (PHEV) and battery electric vehicle (BEV) inverter contracts with a European automaker. The introduction of the Viper D further solidifies the company’s technological leadership in high-voltage electric drive systems, offering new solutions for enhancing the performance of electric vehicle powertrains.
Modular Design Accelerates Product Development to Meet Diverse Needs
BorgWarner’s iDM adopts a modular design, structuring hardware and software as adjustable building blocks. This architecture enables automakers to quickly modify output power, cooling methods, or control logic without altering the core framework, thereby shortening product development cycles and accelerating the launch of new vehicle models. BorgWarner emphasizes that this flexible design effectively addresses the diverse demands of the global electric vehicle market, enhancing product competitiveness.
While BorgWarner has not disclosed the specific scale of the order, the identity of the automaker, or the vehicle models involved, this collaboration reflects the growing global demand for highly integrated and high-performance electric drive systems. The mass production of the iDM will further elevate BorgWarner’s market influence in the electric vehicle powertrain sector, providing global automakers with more competitive solutions.
