| 摘 要： | 变频器供电的电源电压和电流是非正统的，存在着高次谐波，由此引起了附加铜损耗、附加铁损耗及谐波杂散损耗。由变频器供电的三相异步电动机在额定负载下连续运行的稳定温升要比电网直接供电情况下要高，本文通过试验去研究它们温升的高低。

| Abstract: | For the motor supplied from converter, the waves of the supply voltage and current are non-sinusoidal and contain higher harmonics, thus cause additional copper loss, additional iron loss and harmonic stray loss. For three-phase induction motor supplied from converter, the steady-state temperature rise of the motor operating continuously at rated load is higher than that of the motor supplied directly from mains. The paper studies and compares their temperature rises by test. |
