TM4 designs and manufactures electric motors, generators, power electronics and control systems suitable for the commercial, automotive, recreational and off-higway vehicle markets. TM4 contributes to the highest possible energy conversion efficiencies thanks to its expertise in permanent magnet motors, thermal management, coil winding, outer-rotor topology, and motor and inverter control algorithms. TM4 has a worldwide distribution and support network to serve its rapidly expanding global customer base.
The TM4 SUMO systems are designed to interface directly with standard differentials and/or gearboxes and/or e-axles. It makes this series perfect for class 2 to 8 commercial vehicles and light- to medium-duty bus platforms. This series consists of a combinations of high-torque/low-speed reluctance-assisted permanent magnet motor and controller that offer cost-effective solutions for vehicle electrification or hybridization.
