Design of Lower Limbs Powered Exoskeleton

In order to lighten the burden of health care workers and help people with Lower limb insufficiency to do rehabilitation training, this paper designs a model named exoskeletons rehabilitation robot to simulate the human gait, including exoskeletons and scooter structure, and designs the driver module. Finally, this paper uses Workbench software to do the stress and strain analysis, which validates the reliability of the whole design.

新型永磁同步电机的变频调速系统

Halbach电机是一种新型永磁同步电机,独特的永磁体结构使其磁极磁场呈单边正弦分布,可增加气隙磁通密度、削弱转子轭部磁通密度,有利于提高电机的功率密度和效率、减小电机的体积和脉动转矩。针对Halbach电机特点设计了基于DSP2407A的全数字变频调速系统,试验结果表明,此系统性能良好,有利于节能和环保。

电源频率变化对屏蔽式主泵电机性能影响及其设计调整分析

分析电源频率变化对屏蔽式主泵电机性能的影响,以及供电电源频率变化较大时的电机设计调整。通过将某60 Hz电机方案调整成50 Hz方案,采用有限元分析方法对2种方案电机的性能进行仿真计算,得到了2种方案电机的相关性能参数。
