3 (1/6) Nd-Fe-B Bonded Magnets(Compress Molded Type) CM Series This isotropic bonded magnet is made by compounding and compress-molding Nd-Fe-B magnetic material (MQ-P was used) with an epoxy binder. FEATURES Material mixing and kneading technologies Product strength has been improved through proprietary technologies(2% improvement over competitors products). Molding technologies Thin products can be molded and we support high-volume production for products as thin as.3mm(outer diameter of approximate 3 to 6mm). Surface treatment technologies We apply a priming treatment prior to the application of coatings, ensuring excellent reliability. Overall technologies High performance owing to high-density capabilities. Material Features Recommended applications CM8BL(Low-cost) These materials contribute to cost reduction. CD-ROM, DVD etc. Power tool related CM8BLH(Low-cost) These materials contribute to cost reduction. They are largely compatible with CM8B (standard materials) in terms of their characteristics. CD-ROM, DVD etc. CM11SH(High-performance) These materials are suited for delivering good characteristics. Vibrating motors and other They are suited for realizing good characteristics in thin configurations. applications. CM11UH(High-performance) These materials are suited for delivering good characteristics. Spindle motor, small stepping motor, Suited for multi-polar applications in spindle and small stepping motors. etc. SI Units Material CM8B CM8BL CM8BLH CM11SH CM11UH Residual flux density 66±3 62±3 6±3 74±3 7±3 HcB 398±4 398±4 414±4 478±4 438±4 Intrinsic coercive force 717±8 717±8 717±8 717±8 97±8 Maximum energy product [kj/m 3 ] 71.7± ± ± ± ±8. / CHARACTERISTICS DISTRIBUTION Residual flux density [kg] (T) CM11UH 26A 2A F 32A CM11SH 47B CM8BLH CM8BL 42B B 18 47H 44H 4H 38SH 34SH 32AH 42SH REC(Sm-Co) CM(Nd-Fe-B Bonded magnets) NEOREC(Nd-Fe-B) 38UH 31UH 3UH 27UX 3UX 3UX Transverse magnetic field press Axial magnetic field press Intrinsic coercive force 3EV Conformity to RoHS Directive: This means that, in conformity with EU Directive 22/9/EC, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications. 1-1 / / e32.fm
