TM4's wheel motor development and design dates back to 1982, when a group of inventive researchers started working on an innovative compact motor system that could be embedded inside a regular-sized wheel.
Designed for medium and heavy-duty vehicles, the SAM is located between the internal combustion engine and the transmission, acting as a starter, alternator and motor (SAM).
In 2003, TM4 custom-designed the first generation of Electric Traction Systems for the SVE Cleanova. This system is an integrated traction system combining an electric motor and a generator coupled to an internal combustion engine (ICE).
TM4 MOTIVE A
The TM4 MOTIVE A system consists of the MO120 electric motor and the compact CO60 inverter. It was the first efficient turnkey solution created expressly for a range of electric and hybrid applications, with emphasis on light-duty vehicle platforms.
TM4 MOTIVE B
The TM4 MOTIVE B consists of the HSM120 electric motor and the CO150 inverter specially designed for light-duty vehicle platforms.
