Electromagnetic Performance Analysis of High Torque Density Permanent-Magnet Vernier Machine
ABSTRACT
Direct drive technology got more and more attention by the industrial developed countries because of its unique advantages. For the electric power industry, direct drive technology which cancelled the traditional mechanical variable speed institutions (such as mechanical gear box, etc.), linking the motor and load directly, thus avoiding many disadvantages, such as mechanical fatigue, friction loss and vibration noise. Different from other propulsion systems, high performance motor drive has been the key of the direct drive technology, and the application of the direct drive technology field is very wide. Most widely used in the transmission system of electric drive, direct drive motor with high torque density performance has always been one of the relentless pursuits of goals. Then, a new type of permanent magnet motor with high torque density—permanent magnet vernier (PMV) gets to be paid attention to and carried out relevant research. It is based on "magnetic gear effect" work by introducing modulation on the stator tooth structure in the stator poles and the number of armature slots fewer cases , and the winding space harmonics generated with a specific number of poles of the permanent magnets greater interaction in the air gap, in order to achieve a high torque low speed performance.
This paper presents a direct drive system used in the double spokes arranged permanent magnet stators vernier (DSSA PMV) motor, which is designed to full play to the advantages of its high power factor, while being ensured a high torque density motor PMV.
Main research achievements include the following aspects:
1 Based on the principle of the novel field modulation magnetic gear, the principle of PMV machines has been studied. A unified expression of them is summarized and analyzed. Finite-element analysis (FEA) results are given to identify their principle.
2 The topology and working principle of the double-spoke arrangement of stator permanent magnet motor are introduced in detail to prove the impact of their specific design on performance.
3 Use Ansoft/Maxwell software, finite element simulation model, the double stator permanent magnet motor FEM vernier, and then study its electromagnetic characteristics.
Keywords: Permanent magnet motor, vernier motors, magnetic gear, low-speed high-torque, FEM.
