To promote energy saving, we developed a high efficiency brushless DC motor with a new manufacturing method of a stator for compressors. This motor consists of a concentrated winding stator and an interior permanent magnet rotor. The stator has the core structure that we call “a joint-lapped core”. The joint-lapped core is able to open and bend in reverse. While winding the coil, the joint-lapp...

This paper presents a novel matrix converter based topology with less number of semiconductor switches. The proper switching sequence of matrix converter is used to drive BLDC motor directly from single phase without dc link capacitor. A matrix converter fed BLDC motor is simulated in MATLAB. The proposed technique is simple to implement and cost effective. Keywords— Permanent magnet (PM), Brus...

This paper presents the analysis, design and implementation of cost effective sensorless control scheme of Brushless DC Motors (BLDCM). There are several methods proposed in BLDC motor drives to obtain optimum current and torque control with minimum torque pulsation. But while coming to industrial applications, BLDC motor voltage contains harmonics which are caused because of high speed switchi...

The components of blower are composed of motor and impeller. Motors transform electric energy into mechanical rotating kinetic energy and this rotating kinetic energy produces flow through impeller. And thus blower is divided into motor and impeller. In actual development and study, the process of system formation is followed generally by joining the two independent research results. This study...

This paper presents the design optimization of axial flux surface mounted Permanent Magnet Brushless DC motor based on genetic algorithm for an electrical vehicle application. The rating of the motor calculated form vehicle dynamics is 250 W, 150 rpm. The axial flux surface mounted Permanent Magnet Brushless DC (PMBLDC) motor was designed to fit in the rim of the wheel. There are several design...
