摘　　要：参考GB18613中额定负载状态下效率限定值要求,通过对0.75~375kW的26种规格中小型三相异步电动机在50%~150%负载工频运行下效率与功率因数的型式测试验证,研究论证电动机变工况下效率与功率因数间的关系,确定不同工况下效率与功率因数最低取值,为下一步数据仿真模拟验证与电机变工况绿色节能认证指标体系建立提供依据。This paper refers to the efficiency limit value requirement under the rated load condition in GB 18613,and verifies the efficiency and power factor type test of 26 kinds of small and medium-sized three-phase asynchronous motors of 0.75~375 kW under 50%~150%load power frequency operation.The research demonstrates the relationship between efficiency and power factor under the condition of motor under variable working condition,and determines the lowest value of efficiency and power factor under different working conditions,which provides a basis for the next step of data simulation and verification and the establishment of green energy-saving certification index system for motor variable working conditions.
