Automotive parts supplier BorgWarner has released a new integrated axle called the iDM. The modular eAxle contains a transmission, electric motor and power electronics. The iDM is available in three versions, and can be integrated into the front or rear axles of passenger andlight commercial vehicles.
The iDM’s integrated power electronics are designed to allow for a small package, low complexity and minimum losses. It offers full software functionality with an option for control of vehicle dynamics and energy management. The software architecture is adaptable to common platforms such as AUTOSAR, and allows for safety aspects such as ASIL D.
“Operating at 250 to 450 volts DC, the iDM has exceptional torque and power densities ranging from 90 kW to 160 kW and 2,500 Nm to 3,800 Nm,” says BorgWarner. “The advanced transmission technology offers smooth and quiet operation, and the patented bar wound stator motor technology delivers exceptional performance with superior noise, vibration and harshness characteristics.”
“With the iDM, BorgWarner delivers a product family of highly integrated propulsion solutions to drive our customers’ hybrid and electric vehicles,” said Stefan Demmerle, President and General Manager of BorgWarner PowerDrive Systems. “We deliver key elements for electric vehicles: the electric motor, the transmission, the power electronics and the thermal management system.”
