“…13. All the machines have rated speeds of 300 rpm for direct-drive operation while they can provide about 2 times constant-power speed range, which is suitable for electric AGV applications [20]. It can be seen that the interior PMV machines can provide higher torque, power, and efficiency than the conventional PMV counterpart in the whole speed region, further exhibiting the performance superiority of the interior PMV designs due to the improved flux modulation effect.…”

“…Model V has a similar configuration to Model IV. The difference is that the stator slot PMs in Model IV is removed in Model V. The slot/pole combination of Model IV and Model V follows 𝑃 𝑤 = |𝑃 𝑟 − 𝑛 𝑠𝑝 • 𝑁 𝑠 | (3) Model IV and Model V have been extensively investigated [21], [28]- [30], and it can significantly reduce the stator slots number by introducing nsp. Considering concentrated winding, with the same Pr and Pw, the Ns of Model V can be smaller compared with Model I to Model III.…”

Surface-mounted permanent magnet motors (SMPMMs) have been widely used in industrial fields. However, when it comes to direct-drive low-speed large-torque fields, SMPMMs have several problems, such as lower slot filling factor, complicated fabrication, low efficiency, and bulky size. Recently, dual-permanent-magnet Vernier motors (DPMVMs) have been investigated due to their high torque density for low-speed direct-drive applications. However, so far, there is little research that demonstrates the application of the DPMVM for real industrial fields and quantitatively compares the performances of the DPMVM and the SMPMM. This paper studies the application of a DPMVM to the direct-drive industrial turbine as a replacement for conventional SMPMM. Rectangular and trapezoidal PMs are first applied to DPMVM in this paper. The performances of the DPMVM are quantitively compared with two typical SMPMMs. One is the design that has the same stator slots as the DPMVM, while the other has the same rotor pole pairs as the DPMVM. Economic costs are considered to form a thorough comparison between DPMVM and SMPMMs. It is revealed that with rectangular and trapezoidal PMs adopted in the DPMVM, the cost of PMs is significantly reduced with little sacrifice of performance. The efficiency of DPMVM is around 12% higher, and the material cost is reduced by 6.87% compared with the SMPMN.

“…In addition, most of the existing studies are mostly based on the rotor PM or stator PM vernier machine. Although the PMV machine with PM in both the stator and rotor can make full use of the space and improve the torque density of the machine, it will greatly increase the amount of the PMs [35][36][37][38][39][40][41]. In [37], a double-sided PMV machine was proposed to apply in a servo system.…”

Permanent magnet (PM) excited vernier machines capable of high torque density have good potential for electric vehicles while requiring high rare earth PM consumption. To achieve a high torque density at a reasonable material cost, hybrid PM excited vernier machines incorporating both expensive rare earth and low-cost ferrite magnets are investigated in this paper. Various combinations of PM arrangements for the hybrid permanent magnet excited vernier machine are investigated to acquire low cost and superior torque density. The best solution obtained is that the PM on the stator adopts rare earth material while the rotor uses ferrite. Furthermore, the PMs on the stator are arranged in an iron-cored Halbach array, which can reduce leakage flux and enhance flux density effectively and the ferrite PMs are used in the rotor, therefore, high-temperature demagnetization is avoided. Then, the reluctance torque and the cogging torque can offset each other effectively, which is beneficial to reducing the torque ripple and smoothing the electromagnetic torque. Finally, a prototype is manufactured and tested to verify the correctness of the theoretical analysis.
