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...

The Permanent Magnet Brushless DC (BLDC) motor offers higher efficiency, low maintenance, reduced weight and compact construction. For many industrial applications, the BLDC motor is increasingly being used. This paper presents a new sensorless drive scheme for BLDC motor based on the back EMF difference. The commutation point of the drive is determined by detecting the Zero Crossing Point (ZCP...

This paper deals with the Direct Torque Control (DTC) of Brushless DC (BLDC) motor drives fed by four-switch inverters (also known as B4inverters) rather than six-switch inverters (also known as B6 inverters) in conventional drives. The principle of operation of the BLDC motor is firstly recalled considering both cases of B6and B4-inverters in the armature, with emphasis on the twoand three-pha...
