电机中通常需要低扭矩脉动，以减少噪音和机械共振。然而，低扭矩脉动的设计会影响机器的平均扭矩和额定功率。本文研究了定子绕组弦和转子扭斜对普通叠片内磁障转子磁阻同步电机平均转矩和转矩脉动的影响。分析中使用了二维有限元时间步长方法和基本机器方程。结果表明，为了实现低扭矩脉动和对磁阻同步电机额定功率影响最小的总体设计，必须使用全节距定子绕组，并且转子必须按定子槽节距倾斜。必须避免定子槽数量较少。
Low torque ripple in electrical machines is generally required to reduce acoustic noise and mechanical resonance vibration. To design for low torque ripple, however, affects the average torque and the power rating of the machine. In this paper the effect of stator winding chording and rotor skewing on the average torque and torque ripple of the normal laminated, internal flux barrier rotor reluctance synchronous machine is investigated. The 2-D finite element time-step method together with the basic machine equations are used in the analysis. It is shown that to design in general for low torque ripple and minimal effect on power rating of the reluctance synchronous machine, full-pitch stator windings must be used and the rotor must be skewed by a stator slot pitch. A low number of stator slots must be avoided.
