SEM 2 WEEK 5

TITLE:

Soldering the components

OBJECTIVE:

Put the components into PCB become actual circuit.

CONTENT/PROCEDURE :

Before soldering process, I need to identify and study little bit about the components. Using the skill that I learn before, the process going smooth. If I make the wrong identification it will affect my circuit driver. I didn't cut the component's leg because need to show my adviser first to check the circuit and if  the mistake happens such as misplace the component's polarity, the correction can be done easily.

 CONCLUSION:

The progress for soldering process is about 70 percent done.

SEM2 WEEK 4

TITLE:

 Fabricate the actual Printed Circuit Board

OBJECTIVE:

 

Convert the circuit into to PCB layout.

CONTENT/PROCEDURE :

 

Here is the PCB layout that I have draw using Livewire software, before fabricate the circuit into actual printed circuit board

CONCLUSION:
I had successfully fabricate the PCB of my 1phase BLDC circuit driver.

SEM2 WEEK 3

TITLE :

Design circuit diagram using Livewire software

OBJECTIVE :

To investigate the voltage output from the circuit before convert to PCB layout

CONTENT/PROCEDURE :

 I had a problem to simulate the driver circuit  because one of the component which is IR 2110 is not in the library. I went to see Mr. Suhairi to tell him about this problem. We discuss and agree to not doing the simulation and told me to proceed with the actual circuit on the breadboard to test it before doing it on the pcb.

 This figure show the 1 phase BLDC circuit driver using Livewire

CONCLUSION:

      The objective of this week is to understand and investigate the output circuit using  software and replace the components that not available for before convert into PCB layout.

SEMESTER 2 WEEK 2

Title:Research information about the project.
Objective:To ensure student understand about the project.

Discussion/Analysis:

This project will design the drive system for single phase brushless dc motor. The BLDC is droved to move in rotational.

Why use brushless DC motors ?

Brushless DC motors are synchronous motors suitable for use as a simple means of controlling permanent drives (e.g. ABS pumps, EHPS pumps, fuel pumps or cooling fans). This type  brushless DC motor will increasingly replace brushed DC motors. Brushed DC motors require maintenance, e.g. to service coal brushes and commutator. Another major problem with a brushed DC machine is the possibility of brush burnout in the event of an overload or stall condition.

The purpose of the development of the driving system is to control the speed of the motor. The main idea for controlling the speed of the motor is by controlling the switching of the power MOSFET.The power MOSFET will be control by MOSFET driver, while the MOSFET driver will be control by Logic-Gates which , and then the signal will be the input pulse to activate the MOSFET driver. To control the speed of the motor, the input voltage will be varied by user to desire speed.

 
 

SEMESTER 2 WEEK 1

Title:Searching for Component
Objective: to find the component are available on the market before assemble

Discussion/Analysis:

 

I went to Jalan Pasar, Kuala Lumpur to search for components for my FYP. Overall the components are easy to get but some of the component are not available in Malaysia and need to order from oversea through internet. After discussion with supervisor, he suggest to replace that component (IRFB4332) to IRFB640.

WEEK 12

Title: fyp sem 1 presentation

Objective: To present about the project

Discussion/Analysis:

This week, we have been  evaluated  by the examiner in project presentation. Every student will be given two examiners. My first examiner is, Miss. Pusparini Dewi Bt Abd Aziz and second examiner are, Mr. Ahmad Sabry B Mohamad. They ask many questions about  my project. This happens to all the fyp sem 1 student. For me, the aim of this presentation is, to make sure the student is on right track with their project. My examiner was helpful of give new ideas and improvement.  I will suggest these ideas to our supervisor. 

WEEK 11

TITLE : Preparation for fyp presentation

OBJECTIVE : To analyze every part of system use in the project and put it in slide show.

Discussion/Analysis: 


This week, i went to my supervisor and discuss more detail about my project before presentation in week 12. I already do the slide show and the expected question, and discuss with him about the answer. My supervisor ask to follow the format of  slide show that be given on RPS. the correction is implemented.
