Week 11

Title of the activity:  Compile/get the result

Objective:

• To obtain this project working based on expected
• To ensure the project is follow the main objective of this project or not

Content/Procedure:

• Understand the main objective
• Get the result based on objective

The main objective

• To design an automatic controller circuits via combination of software (Proteus) and hardware
• To understand the operation of speed control system for a ceiling fan application.
• To evaluate the functionality of the ceiling fan controller by considering the relationship of the speed change and room temperature.

Result based on objective

• Compare the result between in proteus with hardware part

Ø  Speed1

   

Ø  Speed2

Ø  Speed3

Ø  Speed4

Ø  Speed5

• Operation of speed control system for a ceiling fan application

Ø  Ceiling fan usually using single phase AC induction motor

o   Split-phase permanent capacitor

o   Capacitor start, capacitor run

o   Shaded pole motor

Ø  Motors have windings wound for 18, 20 or 22 poles, resulting in to lower operating speeds (Most common: 18 pole)

Ø  The rotor resistance is very high for wide speed control range using the stator voltage control

Ø  The operating speed range for the ceiling fans are

o   180 rpm to 380 rpm for countries like India

o   110 rpm to 220 rpm for Developed World

o   Low Speed is approx. half of high speed

Ø  Between low and high speeds three to five operating speed at equal interval is achieved using the variable speed control.

• Relationship of the speed change and room temperature

Ø  Based on theory, the speed fan is proportional to the changers of the temperature. So, to prove whether the theory true or not, the speed of ceiling fan of this project must taken when the temperature is change. The value of rpm of ceiling fan has taken using tachometer and represented in graph form.

Analysis:

For the analysis, comparison between software (proteus) and hardware part is tally with other, when the actual temperature in proteus display for speed1 18°C and select the relay1, same like at the hardware part is do the same task. Beside, relationship between room temperature with speed of ceiling fan is proportional, when the temperature increase, the speed fan also increases

Conclusion:

As a conclusion, the main objective of this project is achieved when proved by taken the result of this project, also the objective in this task is achieved.
