The TM4 SUMO family is specifically designed for battery-electric, range-extended and fuel-cell vehicles. The company says these high-performance motors and inverters are engineered to offer maximum flexibility, enabling direct-drive, series-hybrid or parallel-hybrid applications. The technologies are currently available to OEMs for testing and are scheduled for production in the first half of 2021.

The product is designed to allow OEMs to replace internal combustion-based components and does not require major modifications. It can be coupled to diesel engines, natural gas engines and multi-speed transmissions, as well as integrated as part of an e-Axle in heavy-duty and off-highway applications, Dana says.


Packaged for power and optimal value reaching up to 800 volts DC, Dana’s TM4 SUMO HP series offers up to 430 kW of continuous power and 540 kW of peak power, as well as a peak torque value of 2,500 Nm.

Dana says the TM4 SUMO HP series features a new motor with compact concentric winding technology to deliver maximum torque density and leverages Dana’s internal permanent magnet technology.

For the high-power version, the CO200 six-phase inverter has been upgraded with higher power and current output, as well as new connectors. This inverter now delivers twice the power density at 23kW/kg up to 800 volts DC.
