This paper investigated and compared two types of modified model predictive control methods with finite set for six-phase PMSM MTPA control. The first one has conventional cascaded speed and current controller loops where the PI current loop is replaced with a MPC control loop. The second method uses one MPC controller in place of conventional cascaded loops for both speed and current control. The...
Permanent magnet vernier (PMV) machines are attracting more and more attention due to its high power density and simple mechanical structure. In this paper, a novel PMV machine with improved permanent magnet circuit is proposed. For the proposed PMV machine, half of the PMs in the rotor are moved from rotor to the stator slot opening, and Halbach array PMs are employed in the stator. The analysis...
Due to the difference in the working condition and operating mode, permanent magnet (PM) traction motors design concept significantly differs from the traditional industrial motor. Optimization design of the PM traction motor with wide high efficiency range for electric vehicle (EV) application is investigated in this paper. Firstly, the basic design principle and dimension constraint are analyzed...
This paper proposes using grain oriented electrical steel (GOES) in axial flux switched reluctance motors (AFSRM) to improve the torque characteristic employing the material's excellent magnetic properties in the rolling direction. Based on the studying the parameter and switching characteristics of an AFSRM, GOES can be divided into pieces to be arranged in the rotor and stator tooth core so that...
This paper proposes vernier reluctance dual-stator machines with semi-closed slot. The structure of vernier reluctance dual-stator machines with semi-closed slot is firstly given, followed by a comprehensive comparison with the conventional structure in aspects of no load flux linkage, cogging torque and torque. The effect of inner stator shift on the performance of vernier reluctance dual-stator...
Coupling field analysis is a powerful tool to analyze and calculate electromagnetic and thermal performances of permanent magnet synchronous machines (PMSMs). However, most coupling analysis methods are based on the time-consuming recursive algorithm. To overcome this deficiency, this paper presents an electromagnetic–thermal coupling analysis method of PMSMs by introducing an improved ($\mu \,+\,1$ ...
Fractional-slot concentrated-winding has a lot of advantages such as low cogging torque, short end winding and high power density, but the slot fill factor is relatively small with preformed windings when the slot number of machine is small. This paper explores un-even winding turns for double-layer FSCW machines to achieve higher slot fill factor on that situation. After suitable slot-pole combination...
