In a conventional three phase Brushless DC machine with 120° electrical conduction, Harmonics and commutation torque ripple occurs because of changeover of load current from one phase to another at every 60 electrical degrees. This paper presents techniques for diminishing the harmonics and torque ripples in sensor Brushless DC motor. This torque ripple(More)
Torque-Ripple control of brushless DC motor has been the main obstacle in drive system in which speed fluctuation, vibration and acoustics noise should be minimized. This paper proposes the results of simulation and the experiment shows that the stator current can be improved and torque-ripple can be reduced obviously. Model predictive control (MPC) is used(More)
The objective of this paper is to build a simple voltage and current controlled modulation techniques for brushless dc motors using PSIM. In electric traction and most other applications, a wide range of speed and torque control of the electric motor is required. The dc machine fulfills these requirements, but the dc machine requires constant maintenance.(More)
