以永磁直流伺服电机为原动机的伺服机构的设计,其负载匹配问题直接影响系统对功率的要求,也是能否减少系统尺寸重量的重要问题。本文从电机效率、电功率及机械特性三方面分析了负载匹配问题,并介绍了具体的设计方法。
The design of servomechanism with permanent magnet DC servo motor as the prime mover, the load matching problem has a direct impact on the power requirements of the system. It is also an important issue that can reduce the size and weight of the system. This paper analyzes the load matching problem from three aspects of motor efficiency, electric power and mechanical characteristics, and introduces the specific design method.
