This study presents the simulation of brushless DC (BLDC) motor control in MATLAB/Simulink environment with model-based and direct torque (DTC) method extended kalman filter (EKF). In this study, a based on DTC is tested to nonlinear BLDC filter. method, an accurate can be made thanks load moment estimation, which not found literature. As result tests have carried out at low high speeds, it con...

Morphogenesis in the bacterium Streptomyces coelicolor involves the formation of a lawn of hair-like aerial hyphae on the colony surface that stands up in the air and differentiates into chains of spores. bld mutants are defective in the formation of this aerial mycelium and grow as smooth, hairless colonies. When certain pairs of bld mutants are grown close to one another on rich sporulation m...

The Brushless DC (BLDC) motor is a simple robust machine which has found application over a wide power and speed of ranges in different shapes and geometry. This paper briefly reviews the fundamentals behind the motor and also the different types of BLDC motors with different geometries and then presents a new configuration for BLDC motor/generator, which does not use a permanent magnet in the ...

Motor BLDC merupakan motor sinkron dengan permanen magnet, sehingga jenis ini dilengkapi sensor hall-efect. memiliki kekuragan yaitu pengendalian yang lebih rumit terhadap respon pergerakannya performa tidak konstan dan kesanggupan sistem untuk mengejar kecepatan agar mencapai set point ketika berputar menjadi faktor sangat penting sebagai ukuran kinerja motor. Oleh karena itu pada pengaplikasi...

A solar pumping model is proposed in this paper using a Brushless DC (BLDC) motor. Zeta converter used as DC-DC link between the voltage source inverter and PV array. enables soft starting of BLDC motor speed control achieved by simple variation voltage, thereby eliminating need for complex switching circuitry. belongs to class buck-boost hence offers wide range operating voltage. The cost-effe...

In this study, an electromagnetic force induced structural vibration for a brushless direct current (BLDC) motor with variable speed is performed using finite element analysis, as well experiment operating range. The 3-D entire model was used to predict the characteristics range of BLDC motor. To validate (FE) model, modal analysis compared results test. Then, speed, speeds are predicted electr...

For high-speed brushless DC (BLDC) drives, the switching-to-fundamental frequency ratio is usually insufficient. As a result, commutation errors caused by PWM switching delay are significant, which means power switches will take action at inaccurate instants. This cause low-frequency current oscillations and produce additional losses. In addition, conventional method accumulative in sensorless ...
