in this paper, a novel three-phase 12/10 switched reluctance motor(SRM) is investigated. For the conventional 12/10 SRM, the motor has six phases. However, by means of shifting stator pole, the motor has some advantageous characteristic with three phases and short flux path. This is good for increasing the output torque and reduction in cost. Therefore, firstly, the basic structure and principle are...
High speed permanent magnet motor is widely used and has gained more and more attention due to high power density and efficiency. However, its high speed brought up large losses and high temperature rise in the motor. In order to avoid the demagnetization of permanent magnet and damage of winding insulation caused by temperature, multiphysics thermal analysis is applied on the high speed brushless...
A novel permanent magnet generator with adjustable air gap flux is investigated. By using 3-D finite element analysis, the electromagnetic analysis and performance evaluation are carried out. Furthermore, one prototype motor is made and tested. It is clarified that the proposed structure is easy to regulate the air gap flux and demonstrate high performance such as high efficiency and good air gap...
In order to solve problems of taking traditional mechanical bearing to bear the shaft, a novel bearingless switched reluctance motor with hybrid stator poles is proposed in this paper. The rotor needs only one bearing for rotating and constraining the axial movement. The other end can move freely in the radial direction. But it is balanced with the radial force produced by the motor. The proposed...
