When paired with a stator, the rotor\u2019s magnetic field interacts with the stator\u2019s windings to produce motion or generate electricity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In <strong>high-speed magnetic rotor assemblies<\/strong>, the magnets must withstand:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>High rotational speeds<\/strong> \u2014 often exceeding 50,000 RPM<\/li>\n\n\n\n<li><strong>High temperatures<\/strong> \u2014 due to electrical and mechanical losses<\/li>\n\n\n\n<li><strong>Strong centrifugal forces<\/strong> \u2014 which can place stress on magnet bonds and sleeves<\/li>\n\n\n\n<li><strong>Demanding efficiency requirements<\/strong> \u2014 to achieve high torque and power density in a compact size<\/li>\n<\/ul>\n\n\n\n<h2
