This Paper mainly deals with the implementation of vector control technique using the brushless DC motor (BLDC). Generally tachogenerators, resolvers or incremental encoders are used to detect the speed. These sensors require careful mounting and alignment, and special attention is required with electrical noises. A speed sensor need additional space for mounting and maintenance and hence incre...

This paper presents a performance of the canonical switching cell (CSC) converter fed brushless DC (BLDC) motor drive for power quality (PQ) improvement. The use of CSC not only controlled the DC link voltage but also make the inverter to operate at low frequency so that switching losses are minimized. Moreover the use of front end CSC improves the power factor at AC mains. The system needs onl...

This paper deals with a comprehensive study on reducing cogging torque generated in Brushless DC motor drives (BLDC). In such drives, cogging torque suppression techniques that are practically effective in low speed as well as high speed regions are scarcely found in literature. A well-known skewing technique is adapted in the stator slots to reduce the cogging torque using CAD package Magnet 6...

Simulation, design and prototype construction of a low cost three phase permanent magnet (PM) brushless DC (BLDC) motor controller for low power applications is studied in this paper. The drive circuitry is based on the PIC16F877A microcontroller (μC), which –among othersperforms pulse width modulation (PWM) control for a 6-step, 120-degree trapezoidal PM BLDC motor drive. The specific processo...

Abstract— Brushless motors are gaining attention from various Industrial manufactures because of its high efficiency, noise less operation and high speeds. In conventional control methods of Brushless Dc motors, the back electromotive force is assumed to be in ideal form i.e., Trapezoidal form, so that rectangular currents are injected from the inverter. In real time, the back-Emf may not to be...

<span lang="EN-US">This paper presents an efficient interval type 2 fuzzy (IT2F) based on a single neuron proportional–integral–derivative (PID), also known as IT2FSNPID controller. The main purpose of the proposed control technique is to track motion profile brushless DC (BLDC) motor. Also, comparative study was investigated 1 (FT1) and IT2F. IT2F can treat uncertainty nonlinearity BLDC ...

Recently, BLDC motors have become very popular in wide application areas. The BLDC motor does not have a mechanical commutation, and is, consequently, more reliable than the classic DC motor. In recent years, with the increasing number of nonlinear loads drawing nonsinusoidal current, power quality has become a serious problem; hence an optimal control scheme must ensure the desired motor behav...

Solar photovoltaic (SPV) power systems can be employed as electrical power sources to meet the daily residential energy needs of rural areas that have no access to grid systems. In view of this, a standalone SPV powered air cooling system is proposed in this paper, which constitutes a dc-dc boost converter, two voltage source inverters (VSI) connected to two brushless dc (BLDC) motors which are...
