In this research, it proposes the drive method of magnetic material disc by rotation magnetic field. When the rotating magnetic field is given to the magnetic material disc, the magnetic material disc is magnetized by a different phase. Therefore, magnetic attractive force between the magnetic material disc and the rotation magnetic field acts on the vertical direction, the radial direction and the circumferential direction. At this time, only force in the circumferential direction comes to act, because force in the vertical direction and radial direction are composed to be negative each other. The rotating torque is generated by force in the circumferential direction. Therefore, the magnetic material disc rotates. In this research, it aims to clarify the driving principle of this proposed rotor by doing the magnetic flux density measurement, torque measurement and the torque analysis.
