【Abstract】 The thermal control problem of minisized-electromotors in a lunar detector was analyzed.Based on the actual parameters of some minisized-electromotors,a thermal control system using an umbrella-like radiation cooling surface was conceived.The key influencing factors,such as the operating torque of the minisized-electromotors,lunar surface temperature,lunar latitude,etc.,were considered.And the variations of the thermal states of the system with the above-mentioned factors were simulated.The results show that,with the proposed thermal control system,the minisized-electromotors’ temperature can be controlled in the allowed upper limit of the lunar environment.更多还原
