WMC SPIN TOPICS
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. We will concentrate on two main topics: increasing the torque density and reducing the losses.
Synchronous Reluctance Motors could be a good solution for a reliable motor with low production cost, but a fine design is necessary to reduce the intrinsic torque ripple that affects these types of motors. Rare earth magnet cost, and supply chain, drives the technical choice of motor designer, binding some technical decisions. In this presentation we will show how the design of a rare earth free synchronous reluctance motor must take in consideration electromagnetic optimization and also manufacturing/technology constrains.
