| Abstract | This work intends to show some aspects about the mechanical layout and modeling of a BAPTA (Bearing and Power Transfer Assembly)mechanism in development involving a government institution (INPE)and private companies. The design here described is being evolvedfor application in small satellites (0.5 kW with a rigid solar panel of 1.0 kgm 2). The selected concept uses a conventional 1.8§ stepper motor and a 100:1 harmonic drive reduction gearing to achieve a theoretical output step size of 0.018§. Simulations in computer are showing that significant interaction between the solar array and spacecraft can be avoided (spacecraft pitch disturbing velocity is lower than 10-3 deg/sec)with power consumption as low as 3 to 5 W. The adequate determination of the power consumption is possible due to an adequate representation of the magnetic non-linearity in the motor, including its effect on the electromagnetic torque production. The reliable prediction of the important dynamic characteristics of the motor and general system necessitates a precise representation of the flux-linkage data. A good example is the single-step damping, which can be predicted satisfactorily only if the current disturbance and associated power loss in each stator circuit are calculated correctly. This requires that the rate of change of fluxlinkage be defined accuratelyfor any combination of the system variables. |
