Cogging torque is a critical dilemma in Permanent Magnet Brushless DC (PMBLDC) motors. In medium-low power PMBLDC motors, redundant vibrations and forbidding noises arise as result of the harmonic magnetic forces created by cogging torque. This paper introduces simple approach for minimizing motors applying placement irregularities rotor magnets. An angle shift magnets surface-mounted helps to ...

Brushless permanent magnet surface inset machines are interested in industrial applications due to their high efficiency and power density. Magnet segmentation is a common technique in order to mitigate cogging torque and electromagnetic torque components in these machines. An accurate computation of magnetic vector potential is necessary in order to compute cogging torque, electromagnetic torq...

In order to promote the development of green energy applications, this paper selects a 4-pole 24-slot surface-mounted permanent magnet synchronous motor and performs finite element simulation optimization design on it. Firstly, analysis is carried out, performance verified by simulation. Then, parameterized sensitivity cogging torque three-phase current are performed selecting variables thickne...

Cogging torque is the major limitation of axial flux permanent magnet motors. The reduction of cogging torque during the design process is highly desirable to enhance the overall performance of axial flux permanent magnet motors. This paper presents a double-layer magnet design technique for cogging torque reduction of axial flux permanent magnet motor. Initially, 250 W, 150 rpm axial flux brus...
