Hi, I'm looking for some experimental data of Ni-Fe permalloy which has been used as a rotor and bearing material in a magnetic micromotor (variable-reluctance motor). Doing the frictional study of that kind of actuators, I need the wear rate and friction coefficient of the above material. Could someone provide some data?
