Brushless dc (BLDC) motor drives are continually gaining popularity in motion control applications. Therefore, it is necessary to have a low cost, but effective BLDC motor speed/torque regulator. They are used in Residential and commercial appliances such as refrigerators and air conditioning systems with conventional motor drive technology. A Brushless DC (BLDC) drives are known for higher eff...

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 ...

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 proposes a new approach to direct torque control (DTC) method for brushless direct current (BLDC) motor drives. In conventional DTC method, two main reference parameters are used as: flux and torque. In this paper, the new approach has been proposed to improve the BLDC motor dynamic performance. A main difference from the conventional method of it was that only one reference paramete...

Brushless Direct current (BLDC) motors are gaining attention these days in many applications because of their simplicity in its control and high power density. Due to their usage many advances are taking place in field of automobiles in general and locomotives in particular. To have an effective control over the locomotive it is desirable to have control over starting, running and braking of a ...

─ Brushless dc (BLDC) motor drives are continually gaining popularity in motion control applications. Therefore, it is necessary to have low cost, but effective speed/torque characteristics. A Brushless DC (BLDC) drives are known for higher efficiency and lower maintenance. As the name implies, BLDC motors do not use brushes for commutation instead, they are electronically commutated. For effec...

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...

This paper provides a technical review of position and speed sensor less methods for controlling brushless direct current (BLDC) motor drives, including the background analysis using sensors, limitations and advances. The performance and reliability of BLDC motor drivers have been improved because the conventional control and sensing techniques have been improved through sensor less technology....

Two constant current models of Permanent Magnet Brushless Direct Current Motor (PM BLDC) are presented in the paper. In the first part of the paper principle of operation, basic properties and mathematical equations describing PM BLDC models are given. Then, two different constant current models of PM BLDC motor are considered: In the first model, PM BLDC motor is approximated with dc motor; in...

This study focused on efficiency improvement of BLDC motors via reduction of torque ripple, core loss, and permanent magnet loss. To achieve this objective, we proposed an improved 150° commutation method for three-phase permanent magnet brushless DC (BLDC) motors to improve the current waveform. Although the 120° commutation method is generally employed for a BLDC motor, the 150° commutation m...
