Oil cooled e-motors are under-development both in the automotive and aerospace sectors, in a move towards replacing IC engines and conventional fuels. The trend and need to increase the power density of e-motors forces designers to use internal cooling, by injecting the coolant directly inside the motor.
At the same time, the search for efficiency and lighter components pushes the designers towards integrating the e-motor with the transmission, allowing the use of the transmission lubricant to act as the cooling fluid for the e-motor.
The webinar will present an oil cooled e-motor case study demonstrating how the use of Moving Particle Simulation (a mesh-less CFD method) can support the design of oil injection and the optimization of cooling efficiency of e-motors. As most of the players in this sector are working on the development of new designs, the capability to simulate and predict the behavior of the system faster and earlier in the design stage is of paramount importance to shorten the development time.
