摘　　要：由于电流谐波是电动机产生损耗的重要因素,研究变频器供电引起的电流时间谐波,对永磁电动机的影响具有重要意义。以一台功率20 kW、额定转速6 000 r/min和长度为600 mm的潜油电动机为例,运用ANSYS软件分析电流时间谐波对高速永磁同步潜油电动机性能的影响。结果表明:当电动机采用变频器供电时,由电流时间谐波引起的转矩脉动、定转子铁心涡流损耗和永磁体涡流损耗比正弦波供电时大11%、72%和81%。As the current harmonics is an important factor in the loss of the motor,it is very important to study the effect of current harmonics caused by the power supply of the inverter on the permanent magnet motor.In this paper,a 20 kW,rated speed is 6000 r/min,the length of 600 mm submersible motor as an example,the influence of current time harmonic on the performance of high-speed permanent magnet synchronous submersible motor is analyzed by using Ansys software.The results show that when the inverter is used,the torque ripple caused by the current time harmonics,And permanent magnet eddy current losses than the sine wave power supply 11%,72%and 81%.
