摘要
通过分析变频调速电动机的特性及其所带负载的机械特性和负载的工况等方面,阐述变频调速电动机选型时应注意的问题。从电动机的特性、电动机的有效转矩入手,分析在额定频率、小于额定频率和大于额定频率时电动机的机械特性曲线和有效转矩曲线。并通过讨论各种负载和负载工况,提高了变频调速电动机选型时的注意事项。
Throuth Analysis of the Based on the effective torque of the motor, the mechanical characteristics curve and effective torque curve ate obtained under the conditions of the the at, lower than, and over the rated frequency. Through discussion of the the operation condition of various loads, the attentions taken during selection the variable-frequency adjustable-speed motors are analyzed concretely.
