Torque Control of Brushless Direct Current Motor Drives Using Single Current Sensor with High Reliability

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...

Study of Direct Torque Control Scheme for Induction Motor Based on Torque Angle Closed-Loop Control

Abstract: For disadvantages of the large flux and torque ripple and current waveform distortion of Direct Torque Control (BASIC-DTC), the DTC scheme for induction motor based on torque angle closed-loop control was presented and the proposed scheme was realized with three methods of torque angle closed-loop control. The main characteristics of three methods of torque angle closed-loop control f...

Current Control Strategy for the Sensorless Speed Control of Permanent Magnet Brushless Direct Current Motor

─ 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...
