在过去的15年中，同步磁阻（SyR）电机驱动器已被视为许多变速应用中感应电机（IM）驱动器的竞争性替代品，至少在小功率范围内。文献中很少有超过100 Nm扭矩大小的SyR电机的例子。SyR电机的主要优点在于没有转子焦耳损失，这允许获得比相同尺寸的IM更高的连续扭矩。本文介绍了一种250kW、1000rpm工业用同步磁阻电动机，并与同定子感应电动机进行了性能比较。SyR电机的转子专门设计为适合IM竞争产品的定子和外壳。两个电机的实验比较，在再生测试台上，其中一个测试下的两个电机可以加载竞争对手，反之亦然。实验测试的结果证实了SyR电机在额定绕组温度下连续运行时提供更大转矩和更大功率的假设。然而，IM在弱磁能力方面保持了一定的优势，这意味着更大的恒定功率速度范围。
Throughout the last 15 years, Synchronous Reluctance (SyR) motor drives have been presented as a competitive alternative to Induction Motor (IM) drives in many variable speed applications, at least in the small power range. Very few examples of SyR motors above the 100Nm torque size are present in the literature. The main advantage of the SyR motor lays in the absence of rotor Joule losses that permits to obtain a continuous torque that is higher than the one of an IM of the same size. The paper presents a 250kW, 1000rpm Synchronous Reluctance motor for industrial applications and its performance comparison with an Induction Motor with identical stator. The rotor of the SyR motor has been purposely designed to fit the stator and housing of the IM competitor. The experimental comparison of the two motors is presented, on a regenerative test bench where one the two motors under test can load the competitor and vice-versa. The results of the experimental tests confirm the assumption that the SyR motor gives more torque and then more power in continuous operation at rated windings temperature. However, the IM maintains a certain advantage in terms of flux-weakening capability that means a larger constant-power speed range.
