单、双层不等匝正弦绕组线模的尺寸计算

为了减少谐波磁势,削弱同步附加转矩,提高电机的效率及改善电机性能,三相异步电机的定子线圈广泛采用单、双层不等匝正弦绕组(以下简称正弦绕组)。由于正弦绕组每极每相下各线圈的跨距和导体数均不相等,其绕线模尺寸计算复杂,文章介绍了它的计算方法。

Dimensional Calculation of the Wound Model for Single-double Layer Unequal-turn Sine Windings

In order to decrease the harmonic magnetic motive force and synchronous additional torque and increase the efficiency and performance of the 3-phase induction motor, the single-double layer unequal-turn sine windings （Hereinafter referred as wine winding） were applied into the stator coil. Since their span and turn number of the coil in each pole were unequal, the dimensional calculation of the model became very complicated. A calculated method was introduced.
