TM4 SUMO Product Brochure

Product catalog summary

Overview: The document introduces the TM4 SUMO™ series, a family of high torque electric powertrain systems designed for medium and heavy-duty vehicles, including electric and hybrid commercial applications. These systems offer direct drive for maximum efficiency and are available in medium (<450 Vdc) or high (<750 Vdc) voltage ranges.

Specifications: The powertrain systems feature permanent magnet motors with outer rotor topology for maximum torque density and low electromagnetic noise. They support four-quadrant operation and are compatible with standard rear differentials without needing an intermediate gearbox. The systems boast a peak efficiency of 97% and are optimized for vehicles such as buses, delivery trucks, and shuttles.

Motor and Inverter Features: The motors are available in various models with peak power ranging from 200 kW to 250 kW and continuous power from 150 kW to 245 kW. They offer peak torque between 2100 Nm and 3400 Nm and continuous torque from 1225 Nm to 2200 Nm. The inverters feature Reflex™ gate driver technology, EMI filters, and support for 3-phase or multi-phase configurations.

Controller and Software Features: The systems are compatible with TM4’s advanced diagnostic software suite and support CAN 2.0b communication interface. They offer torque or speed control options.

Applications: TM4 SUMO systems are suitable for a range of applications, including city buses, delivery trucks, tow tractors, mining, marine applications, and other heavy-duty vehicles.

Standards and Compliance: The systems comply with automotive standards such as AEC-Q100, AEC-Q101, and ACE-Q200, and meet electromagnetic compatibility (EMC) requirements. They also adhere to toxic materials and flammability standards like ROHS, ELV, and UL94-VO.

Weight and Dimensions: The SUMO MD system weighs 220 kg with a diameter of 478 mm, while the SUMO HD system weighs 337 kg with a diameter of 505 mm. The CO200 and CO300 inverters weigh 26 kg and 36 kg, respectively.
