三种不同的同步电机与永磁体在定子（双凸极永磁体，磁通反向永磁体，和磁通切换永磁电机）进行了比较，作为一个工业驱动45千瓦，400 V Y，和1000…3000分-1。为了比较，有限元方法模拟进行调查的机器的转矩密度，并解释的结果的基础上的磁共能。仿真结果表明，磁链切换电机产生的转矩密度最高的三个机器。因此，建造了原型磁通切换机，对其进行了测试，并与转子表面有磁铁、尺寸（定子外径d so = 314 mm，轴向长度l Fe = 180 mm）和额定值相同的传统永磁同步电机（PMSM）进行了比较。测量结果表明，传统的永磁同步电机和磁通开关机具有大致相同的电气行为。
Three different synchronous machines with the permanent magnets in the stator (doubly salient permanent magnet, flux reversal permanent magnet, and flux switching permanent magnet machine) are compared for use as an industrial drive for 45 kW, 400 V Y, and 1000 …. 3000 min −1 . For comparison, finite element method simulations are carried out to investigate the torque density of the machines, and the results are explained based on the magnetic co-energy. The simulations show that the flux switching machine generates the highest torque density of the three machines. Therefore, a prototype flux switching machine is built, tested, and compared with a conventional permanent magnet synchronous machine (PMSM) with magnets on the rotor surface, the same size (stator outer diameter d so = 314 mm, axial length l Fe = 180 mm) and rating. The measurements indicate that the conventional PMSM and the flux switching machine have roughly equivalent electrical behaviour.
