The first paper described the manufacture of injection-molded and the static capacity test of plastic magnetic gears. The second paper describes the results of dynamic test. (the noise test, wear test and measurment of temperature of plastic gears teeth) As regarding preventive gear noise, pastic magnetic gears are superior according to the results of the experiment. Those gears show a great deal of wear when the gears are used with no lubrication, but little wear when grease and oil lubrication was appplied. It was possible to put the injection-molded plastic magnetic gears to practical use in this experiment. During the temperature rise of the plastic gear teeth, both the measurements and authors' calculation formula to deal with viscoelastic materials were compared. The two values agreed with each other. The value of temperature rise was only slight within the load of the magnetic force level. It was possible to put the injection-molded plastic magnetic gears to plactical use in this experiment.
