With an Assembled & Tested PCB

DIY kit comes with an Assembled and Tested PCB ensuring 100% output guarantee. Includes hardware for assembling project from scratch. Fully supported by elaborate documentation, audio visuals and tools to independently carry out the project work.


The project is designed to protect an induction motor from single phasing and over temperature. Providing a protection system is very important in industries, using lot of motors such that production is not hampered owing to failure of any motor.

The basic idea for the development of this project is to provide safety to the industrial motor/pump/lift Motor etc. If any of the phases, out of the 3 phases is missing or if the temperature of the motor during operation exceeds the threshold value, motor stops immediately.

The system uses a 3-Phase power supply where three single phase transformers are connected to it. If any of the phases is not available the corresponding transformer stops supplying power to the circuit. This leads to one of the four relays getting switched OFF.

The main relay which is powered through a set of four relays gets disconnected because of one relay not being powered. Thus the main relay that delivers 3 phase supply to the motor gets disconnected. A thermistor is connected to the motor body to sense the temperature. If the temperature increases then supply to the fourth relay is disconnected.

Further the project can be enhanced by using current sensors for over load protection and phase sequence sensor for protecting the motor from applying wrong phase sequence.

We came to know about edgefx is through searching key words wireless power transfer in google
By seeing the website it so attractive and it is easy to understand
I received with the right components in right time
supported team helped me to purchase kit online
develop more projects related to all aspects
i will refer this site to our friends
i will go through your blog

While searching in the Net I came to know about Edgefx and I used the keyword Electrical readymade project to find the Edgefx.I decided because it is easy to understand I like the database like Report and videos. Yes the kit delivered on time with the right components.I purchased through online.Delivery aspect should be improved.
