Heavily efficient
The TM4 SUMO HD systems are designed to interface directly with standard axles (no gearbox required).
Its direct drive/gearless approach makes it the perfect match for any heavy-duty commercial vehicle platforms, bus platforms and off-highway applications.
Motor features
- Proven permanent magnet technology for optimal efficiency
- Outer rotor topology for maximum torque density
- Low electro-magnetic audible noise
- Low-cogging and ripple torque for better NVH
- Four-quadrant operation
- Thermal protection
Inverter features
- 9-phase high-voltage inverter
- Variable switching frequency
- ReflexTM gate driver technology for high power and
- current densities
- EMI filter
- Best-in-class power density
- High efficiency
The direct-drive advantage
TM4 SUMO high torque motors can interface directly with standard rear differential without the need for an intermediate gearbox.
A direct drive system allows for the following benefits:
- High reliability: removing the gearbox means removing the most mechanically complex and maintenance intensive part of the vehicle
- Easy to fit between the H beam of the truck or in the engine bay of the city bus: no need to modify the vehicle architecture
- Low maintenance: Dana TM4 direct-drive motors require no maintenance
- Fast ROI
