The space vector modulation (SVPWM) of Brushless DC motor (BLDC) is different from that of permanent magnet synchronous motor for its turn-off phase and trapezoidal back electromotive force. To overcome these problems, a SVPWM method is presented in this paper. The application of SVPWM to Brushless AC drives has been investigated extensively. This paper describes its application to BLDC drives ...

Due to the intensified BLDC motor applications in recent decades, Power factor correction (PFC) converters have attracted several researchers. In previous research works, SEPIC converter with the Tapped Inductor model operating in Discontinuous Conduction Mode (TI-SEPIC-DCM) to produce significant results. This work proposes a novel idea of bridgeless rectifier for PFC to enhance rectifier powe...

In this paper, we address the leader following consensus of BLDC motor by considering the effect of delay in the network. Since BLDC motors are used in a variety of application such as Automobiles, Servo drives, UAV’s, Aeronautics and other areas requiring higher efficiency and ease of control, therefore we think it is necessary to study the behavior of motor from the Multi-Agent point of view....

While creating an industrial system which has an electric motor, the designers should to be think over not only control method but also motor type to create successful and efficiency system. If created system is an electric vehicle, designers have two powerful candidates as traction motor: Brushless AC (BLAC) or Brushless DC (BLDC) motors. In this study, a comparative performance investigation ...

What I cannot create, I do not understand. Abstract T he auto-commutated permanent magnet synchronous motors, or brushless DC motors (BLDC), are more and more used in many different industrial low power (< 1 kW) applications. BLDC motors have the phase coils on the stator and the permanent magnet(s) on the rotor. Besides many advantages provided by this configuration , a drawback is that the po...

This paper presents an efficient and robust control scheme of Fuzzy Logic Electronic Differential Controller (FLEDC) for sensorless drive based electric vehicle. The proposed system consists of two Brushless DC motors (BLDC) that ensure the drive of the two back driving wheels of an electric vehicle. Electronic differential controller (EDC) ensures the maximum torque and it can control both the...

The main purpose of this paper is to describe the four-switch brushless dc (BLDC) motor drive for varoius applications. For effective utilization of the developed system, a novel direct current controlled pulse width modulation scheme is designed and implemented to produce the desired dynamic and static speed–torque characteristics. Also, t h e feasibility of the four-switch converter. Keywords...

This paper introduces a BLDC fan motor driver system using modified sinusoidal PWM (SPWM). The driver board is assembled in the motor to minimize system size. Based on the signal from the hall position sensor on the board, the controller generates the SPWM to the power module to drive the BLDC motor. Because it's SPWM instead of square PWM, there is no pulsation torque. The simulation and exper...

Further, the electronic control that BLDC motors offer is critical to statutory vehicle requirements such as energy-saving, reduced environmental impact, and the creation of safer vehicles. BLDC motors are also useful for variable-speed applications where space is tight, such as fuel pump control and electronic power steering. In these types of applications, electronic control is essential due ...
