Due to their simple structure, high efficiency, fast dynamic response, Permanent Magnet Brushless DC (PMBLDC) machines are extensively used in automation, consumer electronics, electric vehicles and medical and industrial applications. Availability of these high energy density permanent magnet materials enhances the performance of PMBLDC motor drive and also reduces the size and losses in these...

The paper presents simulation results of hybrid fuzzy logic with proportional plus conventional integral-derivative controller for the speed control of permanent magnet brushless dc (PMBLDC) motor. Although conventional PID controllers are widely used in the industry due to its simple control structure and ease of implementation, these controllers pose difficulties under the conditions of nonli...

This paper presents a hybrid fuzzy logic proportional plus conventional integral-derivative controller (FP+ID) for the speed control of permanent magnet brushless dc (PMBLDC) motor. Though, PID controllers are commonly used in practice, they have failed to perform satisfactory under nonlinearity, load disturbances, parameter variation etc. In this paper, the performance of the permanent magnet ...

In this paper, A power factor correction (PFC) based single ended primary inductor converter (SEPIC) is used to regulate DC bus voltage of voltage source inverter (VSI) to run PMBLDC motor . Permanent magnet brushless DC motor (PMBLDCM) is used in air-conditioning systems and runs at rated torque and variable speed to achieve energy conservation. The analysis, design and performance of the prop...

This paper introduces novel a two-phase permanent magnet BLDC (PMBLDC) motor with both an asymmetric tooth and an auxiliary tooth in order to improve the dead point, efficiency and torque ripple. To calculate the merits of introducing each of the asymmetric tooth and the auxiliary tooth, characteristic analysis is performed respectively using finite element method (FEM). To maximize performance...
