Direct Torque Control of Permanent Magnet Synchronous Motors With Non-Sinusoidal Back-EMF. (May 2008) Salih Baris Ozturk, B.S., Istanbul Technical University, Istanbul, Turkey; M.S., Texas A&M University, College Station Chair of Advisory Committee: Dr. Hamid A. Toliyat This work presents the direct torque control (DTC) techniques, implemented in fourand six-switch inverter, for brushless dc (B...
Brushless DC motors (BLDC) are widely used in industrial areas. The BLDC motors are driven either by indirect ACAC converters or by direct AC-AC converters. Direct AC-AC converters i.e. matrix converters are used in this paper to drive the three phase BLDC motor and it eliminates the bulky DC link energy storage element. A matrix converter converts the AC power supply to an AC voltage of variab...
This paper presents performance analysis of permanent magnet brush less dc motor (BLDC) using FEA based CAD package MagNet 6.13.First the characteristics of the standard BLDC motor is analysed. Then the design modifications are introduced and the performance of the machine is analysed. Based on the results optimum design is obtained.

This paper refers to the design of a motor control system required for a brushless DC motor control application. The paper work includes the design and development of the necessary hardware supported by appropriate embedded software. The BLDC motor has certain advantages over other motors such as maximum torque to weight ratio, high speed etc, but it requires an electronic commutator such as a ...
AbstractIn this paper, an efficient simulation model for fuzzy logic controlled brushless direct current motor drives using Matlab/Simulink is presented. The brushless direct current (BLDC) motor is efficiently controlled by Fuzzy logic controller (FLC). The control algorithms, fuzzy logic and PID are compared. Also, the dynamic characteristics of the BLDC motor (i.e. speed and torque) and as w...
The components of blower are composed of motor and impeller. Motors transform electric energy into mechanical rotating kinetic energy and this rotating kinetic energy produces flow through impeller. And thus blower is divided into motor and impeller. In actual development and study, the process of system formation is followed generally by joining the two independent research results. This study...
This paper presents an influence issue improved by victimisation buck-boost convertor for BLDC motor drive as a value effective answer for low power applications. AN approach of speed management of BLDC motor by dominant the DC link voltage of VSI (Voltage supply Inverter) is employed. This facilitates the operation of VSI at fundamental change by victimisation the electronic commutation of BLD...
Brushless DC (BLDC) motors are widely used for many industrial applications because of their high efficiency, high torque and low volume. In view of the problem that the current control method of speed regulation system of BLDC motor has poor control effect caused by fixed parameters of PID controller, an adaptive PID algorithm with quadratic single neuron (QSN) was designed. Quadratic performa...
