RELAY• Relay is an electrically

operated switch

• Very fast in operation

• Used to protect electrical devices

• It reduces number of switches in the circuit

• Small current can be used to switch on and off a circuit with the large current

More than 75% of Industrial Applications AC 3 Phase IM is Majorly used….

Operation to be Perform

• Start and stop

• Forward and reverse

• Jogging and inching

• Dynamic braking

• Speed control using phase control

• Speed monitoring

Jogging and Inching and Braking:Jogging refers to repeated starting and stopping of a motor in short bursts to perform a particular movement such as moving a crane to a particular location. The motor is operated on full power. Special Jogging circuits are available. Inching is similar to Jogging and the two are often confused with each other. Inching involves short thrusts of motion at reduced power. The motor is made to run at a reduced voltage.

Jogging should not be done more than 5 times in a minute. This is because jogging can cause the motor to overheat. If Jogging is to be done frequently, the starter of the motor should be derated. Special Jogging Blocks are also available which prevent the motor from being jogged more than 5 times an hour by logging the number of starts per hour.

SoftwareAndroid app development using High level Language

Eclipse IDE and ADT(Android Development Kit) Integrated developed environment use any type of language like C, C++, Java etc.

Android studio GUI (Graphical User Interface)

GUI based android Application developmentAndroid SDK (standard development kit)different versions of android like Eclairs ,Jellybean, Kit Kat, Marshmallow….

Software

Arduino and Others

• Arduino v1.6 for audio programming

• Mat lab for simulating power circuits

• Eagle PCB for PCB Designing for TRIAC

• Fritzing for Arduino and bread board connection

SOFTWARE USED:MIT APP INVENTOR

App Inventor for Android is a open-source web application .

It allows newcomers computer programming to create software applications for the Android operating system.

It uses a graphical interface, very similar to Scratch and the StarLogo TNG user interface.

MIT APP INVENTOR 2 It allows users to drag-and-drop visual objects to create

an application that can run on Android devices. In creating App Inventor, Google drew upon significant

prior research in educational computing, as well as work done within Google on online development environments

App Inventor and the projects on which it is based are informed by constructionist learning theories.

It emphasizes that programming can be a vehicle for engaging powerful ideas through active learning.

The MIT AI2 Companion app enables real-time debugging on connected devices via bluetooth.

APPLICATION:Many industrial applications require adjustable speed and

constant speed for the improvement of quality product….

Intensity of light can also be controlled with a help of android application…

Motion drive applications like such as Conveyors, Blowers, Pumps as well as many direct drive or geared application…

Wood working machineries, Air compressors, high processors, water pumps, vacuum pump and high torque application….

PROS: Remote Operation is achieved by any smartphone

with the Android OS…...

Technical expert controller is not required, easy GUI control….

Android and Arduino are open source system to develop any programming code...

Bluetooth consumes less power so more preferable….

More useful for patient and disabled persons….

A smartphone can control multiple machines, So Control wiring are reduced…

FUTURE SCOPE:GSM module adding with Bluetooth technology to

make long and short distance speed control of the induction motor.

The Load Current also can able to monitor in Smartphone…

By using temperature sensors to stop the motor at Over load or over heated Condition and it can also able to Monitor…

Variable frequency speed control also Possible by Introducing inverter drive…

Multiple Motor control also possible in this smart phone Application..

CONCLUSION:

The objective of the project has been achieved for developing hardware and software for controlling the speed of the induction motor using android application.

The demand for wireless operating devices has been increasing because it is more preferable than wired devices.
