Dana launches direct-drive electric powertrainUS-based Dana Incorporated (www.dana.com) launched its latest direct-drive electric powertrain — the TM4 SUMO LD — at the end of April.

The motor-inverter combination (suitablefor Class 2 through Class 6 vehicles) extends the comprehensive TM4 SUMO line-up, which is currently powering more than 12,000 electrified vehicles.

Designed primarily for today’s direct-drive architectures, the TM4 SUMO LD will also provide a modular solution for transitions to widespread e-Axle platforms.

When integrated with one of Dana’s numerous electrified axle solutions, it can be configured for light-commercial vehicles, minibuses and medium-duty trucks and buses, as well as heavy-duty Class 8 hybrid vehicles.

Christophe Dominiak, Dana’s chief tech-nology officer, said: “The TM4 SUMO direct-drive electric powertrain is a globally adopted, road-proven and highly efficient solution used in thousands of electrified vehicles.

"It has been engineered into multiple Spicer Electrified products and can be adapted to the architecture requirements of our customers, from direct-drive solutions to fully integrated e-Axle designs.”

With three available models, the TM4 SUMO LD offers up to 250kW of continuous power and 1200Nm of torque.

Its new winding technology, combined with an innovative internal permanent-magnet rotor design, creates a more lightweight and compact solution to fit smaller vehicles.

The SUMO LD is matched with the industry-proven three-phase CO150 inverter, which is already used in thousands of vehicles world-wide.

It can be optimised to offer the best driveline efficiencies to different vehicle platforms, based on selected duty cycles.
