分数槽集中绕组（FSCW）或齿绕组已被证明是非常有益的同步和永磁（PM）电机。然而，大量的空间谐波的气隙磁通呈现FSCW配置不适合感应电动机。本文提出了使用多层FSCW缠绕在两层定子槽，消除子（基波的一小部分）和高阶空间谐波，并提供了一个非重叠的绕组布置。这种绕组结构具有几个优点，如高扭矩密度，较短的端部绕组长度和更容易制造的外转子鼠笼式感应电机的泵，风扇和轮毂驱动器。提出的绕组配置和传统的分布式绕组之间的设计比较。
Fractional Slot Concentrated Windings (FSCW) or tooth windings have been proved to be very beneficial for synchronous and permanent magnet (PM) motors. However, the abundance of space harmonics in the air gap flux have rendered FSCW configurations unsuitable for induction motors. This paper proposes the use of a multi-layer FSCW wound around two layers of stator slots that eliminates sub (a fraction of fundamental) and higher order space harmonics and provides a non-overlapping winding arrangement. This winding configuration has several advantages like high torque density, shorter end-winding length and easier manufacturability for outer rotor squirrel cage induction motors for pumps, fans and in-wheel hub drives. A design comparison is performed between the proposed winding configuration and a conventional distributed winding.
