Swedish Automaker Polestar Designs New PM Motors for Its High-Performance EVs, Plans Magnet Recyclingwith Cyclic Materials
Swedish automaker Polestar is rapidly expanding its production of electric vehicle models with high power output and speedy performance. Begun as an auto racing engineering enterprise, the company’s approach is to focus on exceptional design for high performance while conducting manufacturing through the facilities of others and focusing on overall sustainability — including use of recycled magnets.
Case Study: Maximizing Permanent Magnet Motor Efficiency with Magcam Technology
Magnet quality matters for the performance of permanent magnet electric motors. That is the main conclusion of this case study, where we show that e-motor manufacturers can realize an impressive factor
of 2x to 4x improvement on key motor performance characteristics, such as torque ripple and cogging torque, by optimizing magnet quality in the early stages of motor production.
Neuranics: Glasgow Spin-out Develops Tiny TMR Sensors for Biomagnetic Sensing
Neuranics, a recent spin out from the Universities of Glasgow and Edinburgh, has developed pioneering magnetic sensor technology that can bring breakthrough capabilities in health, fitness and metaverse
applications. Building low-profile magnetic sensors that can detect the magnetic fields generated by the muscles and the heart, the company is releasing a product development kit for design engineers.
Tech Tips: Removing the Bottleneck in Welding Electrical Conductors for EVs
The need to increase the rate of joining electrically conducting components has become critically important in the electric vehicle sector as it is emerging to be the bottleneck of manufacturing, according
to Alex O’Farrell, development engineer with Cambridge Vacuum Engineering.
