The project is designed to develop a four quadrant speed control system for a DC motor. The motor is operated in four quadrants i.e. clockwise; counter clock-wise, forward brake and reverse brake. It also has a feature of speed control.

The four quadrant operation of the dc motor is best suited for industries where motors are used and as per requirement as they can rotate in clockwise, counter-clockwise and also apply brakes immediately in both the directions.

In case of a specific operation in industrial environment, the motor needs to be stopped immediately. In such scenario, this proposed system is very apt as forward brake and reverse brake are its integral features.

Instantaneous brake in both the directions happens as a result of applying a reverse voltage across the running motor for a brief period and the speed control of the motor can be achieved with the PWM pulses generated by the microcontroller.

The microcontroller used in this project is from 8051 family. Push buttons are provided for the operation of the motor which are interfaced to the microcontroller that provides an input signal to it and in turn controls the speed of the motor through a motor driver IC. Speed control feature by push button operation is also available in this project.

This project can be enhanced by using higher power electronic devices to operate high capacity DC motors. Regenerative braking for optimizing the power consumption can also be incorporated.

I came to know about Edgefx through Internet.I Trusted Edgefx that was the reason I bought a kit from Edgefx. I like the extra components set, Documentation in my kit.The kit delivered on time with the right components.Edgefx team is very respectable.Mat lab based projects should be implemented & even Documentation should be improved further.

While I was searching in the net I found Edgefx and I decided to buy a kit from Edgefx.I like the Report in my respective kit.Suggestion is that I am expecting more innovative projects.

My friend suggested me that Edgefx kit is excellent.I like the PCB and components.Suggestion is that there should not be any model number on the PCB.
