转子端部分段连接的笼型感应电动机

A New Cage-rotor Induction Motor with Splitted End Rings

将感应电动机笼型转子绕组端部采用分段连接的方法 ,在笼型感应电动机转子采用普通导电材料的情况下 ,提高转子折算至定子边的电阻或阻抗 ,对于变极感应电动机 ,则可以做到每种极数对应不同的转子折算电阻或阻抗 。

A new cage-rotor induction motor with end rings divided into some sections is presented to increase the rotor impedance by using the ordinary conductive material. The method of splitting rotor end rings can also be used in pole-changing motors, in which there is such different rotor impedance for different pole numbers that the starting or pole-changing switching current may come down and the torque may come up. An example with 10/40 poles is given.
