机械系统中原动机的设计

Prime Mover Design in Mechanical System

原动机是机械设备中的重要驱动部分,它的工作性能直接影响整个设备的效率及使用寿命.以机械系统中最常用的原动机——电动机为例,介绍了机械系统设计中,选择原动机时要考虑的类型、额定转速、额定电压、工作制以及功率等主要因素,并以实例阐明了机械系统设计中原动机常用的选择方法及步骤.

Prime mover is an important driving parts in mechanical equipment, its performance directly affects the whole equipment efficiency and service life. Article mainly by the most common prime mover in the mechanical system-motor as an example, it introduces the design of mechanical system, to consider when choosing a prime mover type, rated speed and rated voltage, duty and power of main factors, states and mechanical system design of the central plains motives commonly used selection method and steps.
