BorgWarner Secures an Order From a Global EV OEM for Its Integrated Drive Module
The order covers BorgWarner's three-in-one coaxial iDM, with production slated to begin in 2027.
BorgWarner has won an order for its integrated drive module (iDM) from an unnamed global OEM, with production scheduled to begin in 2027.
What Happened
The iDM packages the electric motor, gearbox and inverter as a single unit in what BorgWarner calls a three-in-one coaxial layout. In this configuration, the motor sits on the same axis as the output shafts rather than on an offset parallel axis. The company states this gearbox layout improves packaging flexibility inside vehicles. The oil-cooled motor uses dielectric oil that can run in direct contact with windings and end-turns unlike water-glycol coolant, which must circulate through a jacket outside the stator. Power conversion is handled by BorgWarner's GenIV inverter built into the drive unit, which employs the latest generation of its Viper power switch, designated Viper D.
Why It Matters
The integrated design targets automakers seeking to simplify e-powertrain architecture while improving vehicle packaging. The coaxial layout may help engineers fit drivetrains into vehicles with tighter engine bay constraints. Oil cooling allows direct thermal management of windings without separate coolant circuits. BorgWarner notes the modular hardware and software building-block approach makes the platform adaptable to different customer requirements and can shorten development cycles.
The Bottom Line
BorgWarner has secured a supply agreement for its iDM from an unnamed global OEM, with production set to start in 2027. The module combines motor, gearbox and inverter in a coaxial layout using oil cooling and BorgWarner's GenIV inverter with Viper D switches.
