Abstract: In this paper, it is based on the dynamics analysis about the dishing rotorís gyroscope, and it is under the comsol software, the rotorís effects that is on the rotor by magnetic field and thermal field, and that are simulated. Meanwhile it is concluded that the rotor is under the effect of Magnetic. The current is 100 mA, 200 mA, 800 mA, through the force of dishing rotorís border, it is the biggest place that was established a theoretical model in the flow fields. This is related in the comsol software simulation. At the same time for the dishing rotor sphere of heated, the highest temperature: X part of the border, Y, Z: Magnetic flux density norm (T) 384.3, 32.8, 224.4, 1.2 e-10, for the dishing rotor boundary, the minimum thermal stress field is in the X, Y, Z: Value117.6, 24.7, 24.7, 117.6 e-12.


Keywords: Dishing rotor, Simulation of magnetic, Analysis of thermal field.
