Many electric traction drive systems (ETDSs) are driven by electric motors primarily
composed of high-energy rare-earth (RE) permanent magnets (PMs), such as neodymium …

Permanent magnet vernier machines (PMVMs) gained a lot of interest over the past couple
of decades. This is mainly due to their high torque density enabled by the magnetic gearing …

Conventional active disturbance rejection controller (ADRC) for interior permanent magnet
synchronous motor (IPMSM) drives suffers deteriorated performance in dealing with low …

This paper discusses the development of linear vernier hybrid machines for use in wave
energy converters. A number of topology options are explored to reduce magnet usage and …

Linear permanent magnet Vernier machines (LPMVM) have received more and more
attention in recent years due to the advantages of high thrust density and low thrust ripple …

A novel interior permanent magnet linear vernier machine (IPM-LVM) is proposed and
analyzed in this paper. Compared to the existing surface-mounted permanent magnet linear …

In low-speed applications, variable-reluctance permanent magnet machines are often
proposed due to their efficient use of magnet material and high torque density. This …

With its high thrust density and low force ripple, the linear vernier permanent magnet motor
(LVPMM) is regarded as a good competitor for linear servo applications. However, typical …

In this article, a dual-permanent-magnet-excited vernier machine is analyzed from the
perspective of air-gap field harmonics. The air-gap field harmonics of the machine is …

The most significant assumption of conventional analytical methods (eg, the subdomain
technique) is that the stator and rotor iron cores are infinitely permeable. The magnetic …
