<span lang="EN-US">Brushless DC (BLDC) motor is widely used for various applications such as transportation. BLDC has many advantages compared to brush more compact, high robustness and simplest construction. The maintenance of this also low due absent the inside motor. For electric bicycle application, conventional electromagnetic torque because not properly designed. It faces density in...

The paper presents a methodology for developing adaptive speed controllers in a permanent-magnet brushless DC (BLDC) motor drive system. A proportional-integral controller is employed in order to obtain the controller parameters at each selected load. The resulting data from PI controller are used to train adaptive neuro-fuzzy inference systems (ANFIS) that could deduce the controller parameter...

Developing of fault tolerant control systems (FTCS’s) for permanent magnet Brushless DC (BLDC) motor drives to diagnose and handle various faults have been of the research concentrations in the last decade. In this paper a novel fault diagnosis algorithm for position sensors (Hall Effect sensors) failure of the BLDC motor is presented. Fault detection and identification of Hall Effect sensors a...

Now a day’s Brushless DC motor drives are becoming more popular in industrial applications. The major problem in BLDC drive system is that some disturbances are originated in the drive which will results in errors and reduces the stability of the system. The state variables and control variables of the BLDC drive system are synthesized in this paper. The main objective of this paper is to formu...

Brushless dc motors are widely used in many industrial applications due to their high efficiency, high power density and ease of control. In this paper, sensorless direct torque control (DTC) of bldc motor is implemented using fuzzy logic. In actual DTC both torque and stator flux linkage is controlled. In the proposed system, the control of stator flux linkage is avoided because every commutat...

Brushless DC motor has a rotor with permanent magnet and has no mechanical commutator which leads to many advantages like less maintenance, long life, high reliability, low inertia, low friction and low noise. Since the brush system/commutator assembly is replaced by an electronic controller which can be easily integrated into other required electronics, thereby improving the effective power to...

A prominent and realistic problem in magnetics is the optimal design of a brushless direct current (BLDC) motor. key challenge designing BLDC motor to function efficiently with minimum cost materials achieve maximum efficiency. Recently, new metaheuristic optimization algorithm called Coronavirus Herd Immunity Optimizer (CHIO) reported for solving global problems. The inspiration this technique...

Received Nov 21, 2017 Revised Jan 29, 2018 Accepted Feb 17, 2018 This paper presents a performance investigation of bldc motor employing KY converter. Conventional The landsman converter is used to minimize the ripples but the inverter produces high output power ripples, which in turn affect the output of the inverter in The proposed KY converter reduces ripples and smooth dc supply gives to th...

This study presents the design of a magnetically levitated (maglev) axial magnetic flux brushless direct current motor (AF-BLDC) for an axial blood flow ventricular assist device (VAD). It has three phases, twelve salient stator poles, and eight rotor magnet poles. It is designed in miniature size. Twin AF-BLDC motors are placed in the VAD symmetrically and rotors are coupled to the pump from t...

This paper describes a simple way to control, in a sensorless way, a Brushless DC (BLDC) motor for electric vehicle applications. To control this machine it is generally required to count with a position sensor because the inverter phases, acting at any time, must be commuted depending on the rotor position. Encoders and resolvers have been used for sensing rotor position with respect to stator...
