The Dynamic Simulation of the Three-Phase Brushless Permanent Magnet AC Motor Drives Using Lab View

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,...

Design of a novel phase-decoupling permanent magnet brushless ac motor

Design and optimization of dc brushless permanent magnet motor

Electric motors that have found wide application in various sectors of industry Have unique features such as high reliability, high efficiency, quick acceleration and have small sizes. Brushless DC motors meet these requirements well. In this study, the design of a brushless DC motor speed limits for the particular application at 1800 rpm that can be equivalent to 140 watts output was provided....

Design and Development of Three Phase Permanent Magnet Brushless DC (PM BLDC) Motor for Variable Speed

A major part of the power consumption in the low-wattage reciprocating compressors, used for household refrigeration units, is associated with the motor. A variable speed compressor as opposed to a single speed compressor is known to provide energy savings due to its ability to match the load demand from the pump more closely to the power delivered by the pump. The current article presents an o...

State of the Art on Permanent Magnet Brushless DC Motor Drives

Permanent magnet brushless DC (PMBLDC) motors are the latest choice of researchers due to their high efficiency, silent operation, compact size, high reliability and low maintenance requirements. These motors are preferred for numerous applications; however, most of them require sensorless control of these motors. The operation of PMBLDC motors requires rotor-position sensing for controlling th...
