HybriDrive ® Modular Traction System (MTS) HybriDrive ® Modular Traction System (MTS) Features • Designed to fit in conventional transmission space claim • Vehicle installation flexibility: inline or transverse engine installation • Integrated starter generator • Modular — readily accepts new technology • Meets all industry top-speed, acceleration, and gradeability performance requirements ® The Modular Traction System (MTS) is composed of a traction motor and a traction generator to provide power to the vehicle. The liquid cooled, high power-to-weight ratio electric traction motor connects directly to a standard drive shaft and rear axle to provide traction power and regenerative braking. The traction motor incorporates a fixed ratio reduction gear, eliminating the need for a gear shifting transmission. This provides shift-free propulsion for the transit bus; providing a noticeably smoother ride for passengers than traditional diesel or parallel hybrid buses. The traction motor is the sole source of propulsion for the vehicle and is sized accordingly, providing high power and superior low-end torque. This gives HybrDrive® powered buses exceptional acceleration, performance on steep grades and efficiency of energy re-capture during regenerative braking – this energy is returned to the batteries for subsequent use. The combination of the down-sized engine, generator and traction motor occupies an equivalent space claim of a typical engine/ transmission unit. This system’s design and packaging makes it easily adaptable to multiple bus models and easy to install. The MTS can be installed in-line T-drive, V-drive, or transverse. The hybrid motor’s simple design reduces the cost of maintenance as well as the overall life cycle cost. Traction motor Features • Superior low-end torque • High power-to-weight ratio • Standardized mounting interfaces • AC induction motor — eliminates brush maintenance • Mechanically simple; long life • Self-contained cooling • Long-life Transynd ® synthetic ATF Benefits • Superior acceleration and gradeability • Reduced maintenance • Flexible for worldwide bus platforms • Reliable, low life-cycle cost • Easy installation Traction generator Features • Integrated engine-starting functionality • Brushless permanent magnet • High power-to-weight ratio • Fully sealed and liquid-cooled — meets international standards (IP67 and IP6k9k) • Standard SAE No. 1 interface to engine • Optional arctic start kit includes starter ring gear for engine start capability below -22ºF (-30ºC) Benefits • Quieter start • Eliminates starter motor and flywheel • Reduced maintenance, parts count, and life-cycle cost • Integrated starter generator enables engine stop/start and supports electrical accessories • TB200 supports continuous 65 mph (105 kph) sustained top speed

The Modular Traction System (MTS) is composed of a traction motor and a traction generator to provide power to the vehicle.
The liquid cooled, high power-to-weight ratio electric traction motor connects directly to a standard drive shaft and rear axle to provide traction power and regenerative braking. The traction motor incorporates a fixed ratio reduction gear, eliminating the need for a gear shifting transmission. This provides shift-free propulsion for the transit bus; providing a noticeably smoother ride for passengers than traditional diesel or parallel hybrid buses.
The traction motor is the sole source of propulsion for the vehicle and is sized accordingly, providing high power and superior low-end torque. This gives HybrDrive® powered buses exceptional acceleration, performance on steep grades and efficiency of energy re-capture during regenerative braking – this energy is returned to the batteries for subsequent use.
The combination of the down-sized engine, generator and traction motor occupies an equivalent space claim of a typical engine/transmission unit. This system’s design and packaging makes it easily adaptable to multiple bus models and easy to install. The MTS can be installed in-line T-drive, V-drive, or transverse.
The hybrid motor’s simple design reduces the cost of maintenance as well as the overall life cycle cost.
