摘要如下：Fractional-slot concentrated-winding synchronous
permanent magnet machines (PM) are appreciated for their
simple construction and high torque density. Unfortunately, it is
well known that such fractional slot / pole combinations kill the
reluctance torque potential of salient interior PM rotor
configurations. To date, this has hindered the application of
fractional windings to machines of the Synchronous Reluctance
and PM-assisted Synchronous Reluctance types. This paper
proposes a new fractional slot PM-assisted Synchronous
Reluctance machine with 24 slots and 10 rotor poles. The new
machine is compared to a benchmark 10-pole PM-assisted
machine having 90 slots and distributed windings and to another
competitor with 12 slots concentrated windings. FEA results
show that the new machine is comparable to the distributed
windings version in terms of torque density and losses, and
much easier to be manufactured.

通常磁阻力/转矩的大小和极数与槽数的最小公倍数有关，亦即和磁场脉振的周期有关，周期越大，一般力/转矩脉振幅值越小。磁阻电机要设法利用磁阻转矩，因而设计上和普通的电机就反其道而行了
