SUMO HD HV3500-9P-L

The SUMO HD HV3500-9P-L is a 9-phase motor / inverter system from the TM4 SUMO™ family, designed for heavy-duty commercial vehicle platforms, bus platforms, and off-highway applications. It pairs a high torque / low speed permanent magnet motor with a matched CO300 high-voltage inverter, designed to interface directly with standard axles (no gearbox required), with a direct drive / gearless approach. Built to IP67 / IP6K9K protection and validated against GMW3172 sprung-mass shock and vibration standards, it delivers up to 475 kW peak power and 3415 Nm peak torque in a rugged, automotive-grade package.

At its core is a proven permanent magnet motor matched to a CO300 9-phase high-voltage inverter rated for a 300–800 Vdc operating range, continuous output of 260 kW and 1970 Nm, and a maximum operating speed of 3400 RPM. This configuration is part of the latest 800 V system range, adding Quick Connect with HVIL for safe and easy installation or maintenance and an extended performance envelope. The broader SUMO HD series spans several power and torque configurations, so the per-system ratings below define exactly what this variant delivers.

The SUMO HD HV3500-9P is designed to interface directly with standard axles (no gearbox required), with a direct drive / gearless approach, removing driveline complexity at the vehicle level and easing packaging in heavy-duty commercial vehicle platforms and similar platforms. A Quick Connect option with HVIL and a range of male and female spline interfaces simplify mechanical and high-voltage integration.
