چکیده

This study focused on the efficiency improvement and acoustic noise reduction of brushless DC (BLDC) motors by reducing current harmonics using a novel BLDC commutation method. To achieve these goals, we designed an improved 150° method for three-phase permanent magnet motor that can improve waveform. Although 120° is generally employed motors, introduced to operate with increased similar AC motor. investigated attributes various methods, both theoretically experimentally, determine optimal The results this indicate in terms harmonic reduced torque ripple, allowing it reduce noise.

Proposed Commutation Method for Performance Improvement of Brushless DC Motor

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...

A Comparison Study of the Commutation Methods for the Three-phase Permanent Magnet Brushless Dc Motor

The three-phase permanent magnet brushless dc (BLDC) motor inherently needs an electronic commutation circuit to drive it because it is not a self-commutating motor. It is contrary to the conventional brush motor which commutates itself. This paper presents a comparison study of three widely used different commutation methods in terms of the complexity of the commutation circuit, torque ripple,...

Torque Ripple Reduction of Brushless DC Motor on Current Prediction and Overlapping Commutation

Based on the analysis of the principle of torque ripple with commutation time for brushless DC motor, this paper proposes a method to restrain commutation torque ripple. This method is an improved predictive current control. First, an expression is built about the torque ripple during commutation time. After analysis, the non-commutation phase current is related to torque ripple. Then, a kind o...

Reduction of Commutation Torque Ripple in Sensorless Brushless DC Motor using Fuzzy Logic Controller

Brushless Direct Current (BLDC) motors are widely used due to high reliability, simple frame, straight forward control, and low friction. BLDC motor has the advantage of high speed adjusting performance and high power density. Speaking of the motor drive control, the most important part is commutation control. On the other hand, they show a high torque ripple characteristics caused by nonideal ...
