Cold spray 3D printing leads to new design possibilities in electric motor magnets

Researchers from the National Research Council of Canada (NRC) have developed a cold-spray additive manufacturing process for fabricating permanent magnets for electric motors. The process could lead to cost reductions and new design possibilities. The high-performance permanent magnets used in electric motors serve to rotate the motor when an electrical power is applied. Generally, these motors are made using processes such as powder compaction (sintered magnets) or injection molding (bonded magnets). But these processes, effective as they are, can take a long time and cost a lot of money. Moreover, the shapes these processes can produce are limited in […]
