Surface mounted rare earth magnets help BLDC motors deliver high performance in specialized applications. Design engineers use magnet retention systems to ensure reliable and safe operation at rotational speeds above 10,000 rpm. Metal alloy sleeves can be made with the same methods as rotors and stators—that is, primarily by machining. But their use is limited by size.
Carbon fiber roving requires costly materials and additional manufacturing capabilities but provides effective magnet retention at a greater range of rotor sizes.
The team at Windings views carbon fiber roving as the more versatile technology and is committed to continued leadership in magnet retention research and manufacturing.
