FIERA INTERNAZIONALE DEI MATERIALI E
WMC PRESENTAZIONI SPIN
Electric mobility has changed the way we approach the purchase of a new car. Until now, none of us ever got into a car dealer and asked information about the capacity of the fuel tank, but with electric cars the driving range is the first feature we look for. It is affected by a lot of parameters, including the way we drive, but as electric engineers involved in the design of motors we should focus on important keywords like efficiency, power density and torque density. In this presentation we will show a few examples of innovative design developed in order to find a solution to the growing needs for electrification.
Right from the beginning of the motor designer’s job, important decisions have to be made on the topologies, sizes and shapes. This can be for a single machine, but also often for developing motor families, with the aim to optimize global manufacturing costs. The use of optimization methods is very powerful to search the design space efficiently among various structures, often considering multiple constraints as efficiency, stress, temperature, noise and of course cost. Later in the design process, shape optimization can also be used to refine the design more locally. The presentation will illustrate how simulation process automation and easy access to optimization can help accelerating the choice of the best configurations and shapes when designing electric machines.
