This research aimed at the development of the rotor material for torque limiter. The coercivity of the rotor material is required to be around 80 kA/m. The melt-spun ribbons of Pr-Fe-Co-Ti-B system alloys were prepared by single roller liquid-quenching method. The effect of composition, wheel velocity and heat treatment on the magnetic properties were investigated. The optimum preparation conditions and some of properties were follows: composition, Pr3.5Fe80.5Co8Ti1B7, wheel velocity, 30.0 m/s; heat treatment condition, 675°C for 5 min in Ar atmosphere; magnetic properties were follows; (BH)max=41.4 kJ/m3, HcJ=85.2 kA/m3, Jr=1.39 T, α(Jr)ave=0.01 %/°C (reversible). The value of (BH)max for the isotropic compression molding Pr3.5Fe80.5Co8Ti1B7 bonded magnet prepared by using the ribbons heated at 675°C for 5 min is 10.1 kJ/m3, HcJ=83.4 kA/m3, Jr=0.535 T, and the density is 5.60 Mg/m3.
