有关永磁同步电动机失步转矩和牵入同步转矩的问题

Discussion on Pull-out and Pull-in Torque of PM Synchronous Motors

对永磁同步电动机的失步转矩和牵入同步转矩两个重要技术指标影响因素很多,其中空载电势E0是重要因素,文章着重介绍E0对其影响,并给出E0的取值范围。

Many factors influence two important technical data of the PM synchronous： Pull-in and pull out torque, among which the electric potential under no-load E0 is the most important factor. The paper describes the effect of Eo to the said two kinds of torque and suggests the value range of E0.
