Brushless DC electric motor (BLDC motors, BL motors) also known as electronically commutated motors (ECMs, EC motors), or synchronous DC motors, are sensored brushless motor powered by DC ...
The mathematical model and the design PID speed controller for the brushless DC motor drive system are presented. A Hybrid Bacterial Foraging Particle Swarm Optimisation (HBF–PSO) algorithm is employed in order to obtain the controller parameters assuring enhanced step response performance criterion. ...
This paper presents a single–stage isolated power factor corrected power supply (SSIPP) fed permanent magnet brushless DC (BLDC) motor drive. An advantage of fast voltage regulation with single voltage control loop of SSIPP is utilised to develop a power factor correction (PFC) based BLDC motor drive. The speed of BLDC ...
Brushless DC (BLDC) motors have the performance advantages of DC permanent magnet motors without the need for motor brush maintenance. BLDC motors have the additional advantages of very high base speed (20,000 RPM and higher), quiet operation and energy efficiency. ...
BLDC motors find numerous applications in the position and speed control systems. Such motors are not able to meet the desired specifications since they respond slowly to the input owing to inherent parameters. Hence, a feasible and practically realisable controller is required to meet the desired specifications with improved performance. The proposed simple controller is implemented using a ...
In this paper, the advanced control methods to minimise torque ripple and to maximise power density of a brushless DC motor/generator system. A simple and straightforward torque pulsation control method with copper loss minimisation for BLDC machines is presented first. ...
