Received Feb 14, 2017 Revised Apr 14, 2017 Accepted Apr 29, 2017 Brushless DC (BLDC) motors are becoming an increasingly popular motor of choice for its unique characteristics. The BLDC motor drive is assumed to have trapezoidal back-electromotive force (EMF), rectangular phase currents and together produces the desired torque. However, practical back-EMF waveform might not be exactly trapezoid...

This paper presents the development of an experimental platform to test a real-time controller for a small Permanent Magnetic Brushless Direct Current (PM BLDC) motor using a Controller Area Network (CAN) communication bus. The CAN communication bus transmits and receives information between modules to control the speed, acceleration/deceleration, and rotational direction of the motor. The desi...

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....

چکیده: عیب گردش روغن در یاتاقان­ لغزشی اگر به موقع تشخیص داده شود می­توان از آثار مخرب آن جلوگیری کرد. در این مقاله پس از توصیف عیب مذکور، فرکانس هارمونیک­های ناشی از آن در شکل موج توان لحظه­ای موتور القایی به روش تحلیلی تعیین می­شود. سپس با استفاده از تابع فاصله هوایی مناسب، از روش تابع سیم­پیچ برای شبیه­سازی موتور القایی قفس­ سنجابی با عیب گردش روغن یاتاقان استفاده می­گردد. ترسیم طیف فرکانس ت...

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...
