ELECTRIC POWERTRAIN SYSTEMS FOR MEDIUM & HEAVY DUTY VEHICLES Direct drive for maximal efficiency Available in medium or high-voltage ranges Compatible vehicle controller available Power electronics electric motors / generators

From the TM4 SUMO™ series, TM4 introduces this family of high torque electric powertrain systems for electric and hybrid commercial vehicle applications. Multiple motor models with varying sizes paired with a choice of medium (<450 Vdc) or high voltage (<750 Vdc) inverters provide a wide range of solutions to your electric or hybrid propulsion needs. These high torque/low speed permanent magnet motors are designed to interface with standard rear differentials without the need for an intermediate gearbox. More than 100 breakthrough patents combine to deliver unmatched efficiency and quality...

COMMON CHARACTERISTICS Peak system efficiency Coolant type Developed for performance and durability, TM4 SUMO systems are optimized for medium- and heavy-duty electric and hybrid vehicles such as 6-18 meter buses, delivery trucks, shuttles, tow tractors and more. By allowing direct drive operation, TM4 SUMO systems reduce powertrain complexity and cost, allowing for a simple, efficient and low-maintenance solution. A direct drive system yields over 10% efficiency gains throughout the driving cycle, representing an equivalent gain in battery usage. Some of TM4’s SUMO systems are offered with...
