4. Introduction
• DC MOTOR WITH PWM SPEED CONTROL IN ALL FOUR
QUADRANTS USING MICROCONTROLLER

5. HARDWARE REQUIREMENTS
• Power supply
• Transformer
• 8051 Microcontroller
• Bridge rectifier
• Regulator
• Motor driver IC
• DC motor
• Push button
• Crystal
• Network resistor

6. Information of each material
• Transformer
it is used to convert 230v to 12v to provide.
• Bridge rectifier
it is employed to convert A. C to D. C supply.

7. • Push Button
Push Button Switch is widely used as a standard
input “button” on electronic projects.
• Voltage Regulator
A DC Voltage Regulator is a device that maintains the
output voltage of an ordinary power supply constant
irrespective of load variations or changes in input A.C
voltage.

8. • Motor driver IC
microprocessors operate at low voltages and a little amount of
current to work whereas the motors need a comparatively
higher voltage and current.
• DC motor
Centre Shaft DC Geared Motor we used our project
DC motor used for load.

9. • Crystal
Crystal and ceramic resonator-based oscillators typically
provide very high initial accuracy and a moderately low-
temperature coefficient.
• Network Resistor
A network resistor is a passive circuit element that is
a combination of multiple resistances. It forms a
convenient solution when the user needs multiple
resistances while constructing a circuit.

10. • L.C.D.
LCD technology is used for displaying the
image in a notebook or some other
electronic devices like mini computers.
• LED
A light-emitting diode (LED) is a semiconductor light
source that emits light when current flows through it. Electrons
in the semiconductor recombine with electron holes, releasing
energy in the form of photons.

11. • 8051 Microcontroller
The Brain of the our project
it's used for synchronization and manages all processes that area
unit in the microcontroller.

13. Four Quadrant Operation of DC Motor:

14. • requires the less maintenance
• Safety to use
• It gives a reliable, durable, accurate, and efficient way of speed control of a DC
motor
• Connection is easy to understand
• Instantaneous break
• Easy to operate.
ADVANTAGE

15. APPLICATION
• Robotic controlled applications.
• One of those applications embodies electrical traction systems, cranes and lifts, and
engine check loading systems.
• In industrial applications like conveyer belts, the right-handed and anticlockwise
operation of the DC motor is the crucial intensity.

16. FUTURE SCOPE
• This is useful for the future robotics application.
• This is useful for automation system and where is dc motor is widely used in
industries.
• This is the helpful for which company want to motor is operate in all four-quadrant.

17. CONCLUSION
• It is proved to be operated so simply.
• The hardware for four-quadrant dc motor speed control using a microcontroller is designed.
• In the proposed model, the PWM technique has been used to control the speed of
the DC motor.
• We conclude that the motor operates in all four quadrants and how to control the motor.
