Due to the simple structure, high torque density, low maintenance, and high efficiency, brushless direct current (BLDC) motors are widely used in automation and industrial applications. A control strategy based on single current sensor is proposed for a four-switch three-phase BLDC motor system to lower cost and improve reliability. The whole working process of the BLDC motor is divided into si...

Abstract This study presents a new predictive control approach for brushless DC (BLDC) motor to smooth its commutation process. The proposed method is applied the BLDC motor's equivalent current. Therefore, this utilises only one prediction equation, which means less calculation than standard schemes. Here, current equation defined according model‐free theory remove back‐EMF voltage estimation ...

Brushless direct current (BLDC) motors are high efficiency synchronous that employed in a variety of applications due to prominent features such as long operational life, low maintenance requirements, and great dynamic response. BLDC driven by energizing the motor stator windings with an inverter circuit. To commute switches, trapezoidal (120°) method is generally used considering back electrom...
