摘要/Abstract

摘要： 电机是强辐射环境中作业机器人完成移动和各种操作必不可少的部件,为了使机器人具有更高的可靠性,以电机系统中的关键部分——电机驱动器为研究对象,开展了基于抗辐射加固的开发设计。通过商用成品(COTS)器件的耐辐射性能测试和筛选,基于器件本征耐辐射性能的驱动器电路分区布局设计,以及基于器件耐辐射性能和驱动器电路分区的屏蔽设计三个层面,设计出一款输出功率2 kW,可承受累积剂量超过2 000 Gy(⁶⁰Co)的三相直流无刷电机驱动器。其样机制造和相关测试验证将在后续开展。

Abstract: Motor is an indispensable part for robots to complete movement and various operations in strong radiation environments. To make the motor more reliable, motor driver, the key part of the motor system, is taken as the research object. The redevelopment design based on radiation hardening has been carried out. Through radiation resistance test and screening of COTS electronics, the partition design of driver circuit based on the electronics’ intrinsic radiation resistance, and the shielding design based on the electronics’ radiation resistance and the partitioned circuit, a three-phase brushless DC motor driver with an output power of 2 kW and a tolerance to total dose of more than 2 000 Gy (⁶⁰Co) was designed. Its prototype manufacturing and related verification test will be carried out in the future.

Key words: strong radiation environment, robot, motor driver, radiation hardening, electronics
