“…Compared with mechanical gear, CMG has the advantages of non-contact transmission, low noise, maintenance-free operation, and inherent overload protection [9,10]. Also, CMG usually has a higher torque density than the motor, so when coaxial magnetic gear and motor are integrated, the torque density of the whole system can be improved [11][12][13]. With the development of the new energy industry, magnetic gear composite motor topology has been proposed due to the excellent characteristics of magnetic gear and is considered to be used in wind power generation and pure electric vehicles [14,15].…”

In coaxial magnetic gear (CMG), magnetic modulation ring is composed of a modulator and a connecting bridge. The torque performance of the magnetic gear is affected by the different structures of the magnetic modulation ring. In this paper, fifteen different kinds of magnetic modulation rings with different structures are proposed; they consist of three different shapes of modulators and five different locations of connection bridges. By using the two-dimensional finite element method (FEM), the magnetic flux density, magnetic line distribution, static torque, and steady-state torque of the CMG with different structures of magnetic modulation ring are analyzed. The results show that the innermost bridge has the least effect on the torque and torque ripple of the CMG, while the outermost bridge has the opposite effect. The torque capacity of the circular modulator and arc modulator is higher than that of the square modulator, and the circular modulator helps to reduce the inner torque ripple, while the square modulator helps to reduce the outer torque ripple. This paper can provide some references for the design of the magnetic modulation ring.

“…7,8 Meanwhile, many types of the direct current and alternating current PM motors were proposed for the wide uses. 9 But, almost all studies for the mechanisms have focused on the coaxial structures. A magnetic gear with intersecting axes (MGIA) only was presented and studied by Liu et al 10 based on FMMG.…”

Based on the magnetic field modulation effect, this article presents a magnetic gear with intersecting axes and straight stationary pole-pieces. Except for a higher utilization of permanent magnets and a greater output torque, the magnetic gear with intersecting axes and straight stationary pole-pieces provides several advantages, such as a smaller volume, higher torque density, and lower processing cost. The magnetic gear with intersecting axes and straight stationary polepiece topology is herein introduced and the deduced constraints of the structural design are outlined. The transmission mechanism is demonstrated by analyzing the output torque in the middle of the air gaps. The effects of the main design parameters on the maximum static torque are evaluated using the finite element method. Based on the orthogonal experimental design and the response surface method, the optimum design results are provided. Prototype of the magnetic gear with intersecting axes and straight stationary pole-pieces has been realized and the static torque has been verified experimentally.
