Abstract：Rotary voice coil motors (VCM) are more widely used in space equipment because of their small volume and flexible installation, to drive some small inertia load to achieve a precise control in a limited range of angles. Disk winding VCM has some special advantages because it’s very thin in axial direction, and can freely rotates with no limits. Stress and temperature raise are two key factors influencing operating reliability of the motors. In this paper, thermal loads of the disk winding VCM under different working state are analyzed, and thermal stress and deformation are calculated in a thermal model. Calculation results indicate that the selected materials of the motor can meet the requirements of long term reliable working. The work in this paper can be used for a reference in practical engineering.
