Electric Motor / EDU / Electric Machine Design Using Simulation
Motors in the EV are called as “electric engines”. Electric machine (E-machine) is an assembly of motor, transmission, cooling channels inside a housing. The design of E-machines is very critical from EMS, thermal, structural & NVH perspectives. E-machine contributes major share of mass in the E-powertrain assembly. Durability of Lightweight design becomes obviously an interesting topic in this regard.
