This study is concerned with the reduction of ripple in thrust force produced a linear Brushless Direct Current Motor (BLDC). To reduce ripples generated force, different methods such as structural solutions are applied both control part and production phase motor. In this study, skew application, which one mechanical methods, proposed. For reason, changes BLDC motor surface magnet-placed trans...

This paper proposes pulse width modulation (PWM) methods for low inductance brushless DC (BLDC) motor drives that minimize the commutation torque ripples. An uneven current of non-commutation phase generates In BLDC drives, two types time delays in PWM also induce critical this paper, analyses and their effects are introduced. Then, proposed to eliminate region conduction region, respectively. ...

Technological developments are increasingly rapid, especially in the field of transportation, electric vehicles, which triggered by increasing scarcity fossil fuels. One propulsion engines that widely used vehicles is brushless direct current (BLDC) motor because this has high torque, constant speed and easy to regulate. This study aims design a BLDC control using boost converter as voltage inc...

This paper reviews the recent developments in the field of sensorless control of Brushless Direct Current motors. Moreover a survey of application of H∞ control theory for robust control, considering the uncertainties like modeling errors and external disturbances in various motors and systems has been carried out. This provides a deeper insight into the recent developments and future scope in ...

This paper studies the use of the PMSM (permanent magnet synchronous machine) generators instead of the induction based alternating current generators in renewable energy sources (wind turbines, combined heat and power, etc.). The paper considers the most significant advantages of the novel permanent magnet technology such as increased specific power, high torque, reduced maintenance costs, inc...

<p class="Abstract">Brushless DC motor (BLDC) is one type of electric that widely used, especially in automotive systems. This used as a driving force vehicles. BLDC chosen because it has the characteristics high efficiency, reliability, and wide speed range. Besides, motors require less maintenance can operate quieter than motors. Even though many advantages, its application use vehicles...

Brushless DC (BLDC) motors are used in a wide range of applications due to their high efficiency and high power density. In this paper, sensorless four-switch direct power control (DPC) method with the sector to sector commutations ripple minimization for BLDC motor control is proposed. The main features of the proposed DPC method are: (1) fast dynamic response (2) easy implementation (3) use o...
