"Borgwarner's comprehensive technology portfolio for electric vehicles makes us a strong partner for automakers worldwide as they move toward a cleaner and more environmentally friendly future," said Dr. Stefan Demmerle from Borgwarner. "We are excited to expand our working relationship with one of our long-term customers to provide a full system solution for their electric vehicle." The iDM product family is available in three different power levels (iDM 90, iDM 120, iDM 160) and can be integrated either at the front or rear axle of electric-powered vehicles. The drive modules support Classical CAN and CAN FD connectivity.

The key benefits of the iDM include its scalable and modular architecture and wide range of gear ratios and electric motor sizes available. Operating at 220 VDC to 480 VDC, it provides up to 150 kW power and up to 3000 Nm, which can be further extended to 160 kW and 3800 Nm. The electric drive product offers quiet operation and the patented hairpin-wound stator motor technology delivers a performance with low-noise, vibration, and harshness characteristics.

The drive module is suited for Class A and A+ passenger vehicles and SUVs. All components used in the power drive are part of the company's portfolio. In addition, the iDM offers software functionality with an option for the high-level control of vehicle dynamics and energy management. According to Borgerwarner the software architecture meets current market requirements and can be adapt to common platforms like Autosar. The software is also functional safe (ASIL-D).
