ASF AVR CONTROL DC MOTOR HOW TO

In 1834, Jacobi Moritz had already presented a highly powerful motor (three times more powerful) than that of Davenport. The reason why he praised Davenport as the original inventor is because he applied for a patent earlier. However, Davenport was not the first person as such to build an electric motor as other inventors in Europe had developed more powerful version earlier. Davenport was the first person to go ahead and seek a patent for a useable electric motor. In the United States, Thomas Davenport was the inventor of the first electric motor. But who was the inventor of the DC motor? Just every other innovation, there are plenty of people who played a role through the development of other equipment. All this is through a rotating movement.ДЄ DC motor is an outstanding piece of electrical device that has revolutionized peoples lives in many different ways. These fundamental operating principles allow DC motors to convert electrical energy from direct current to mechanical energy that can use for propulsion equipment. Upon turning on and off the coils in sequence, there is the creation of a magnetic field that interacts with different areas of the stationary magnets creating torque. The rotating electrical switch allows every armature coil to get energized, thereby creating torque or a steady rotating force.

The windings of the insulated wire get connected to a rotary electrical switch (commutator), that goes ahead to apply an electrical current to the coil windings. One or more coil windings of the insulated wire get wrapped surrounding the core of the motor for purposes of concentrating the magnetic field. The loop of wire has a current that runs through it generating an electromagnetic field that is aligned. The stator is the permanent part of the engine, and the armature is the rotating part.ДЄ DC motor uses stationery sets of magnets found in the stator in addition to a coil of wire. But again, how does a DC motor work? DC motors consist of two essential parts: an armature and a stator. You can find significant mechanisms used to pull hoists and elevators, power vehicles, to small ones found in toys. The output supply (VCC2) has a wide range from 4.5V to 36V, which has made L293D the best choice for DC motor driver.DC motors vary in power and size. Moreover, for protection of circuit from back EMF output diodes are included within the IC. L293D has an output current of 600mA and peak output current of 1.2A per channel. L293D is a dual H-Bridge motor driver, So with one IC, we can interface two DC motors which can be controlled in both clockwise and counterclockwise direction and if you have the motor with fix direction of motion you can make use of all the four I/Os to connect up to four DC motors. H-Bridge Circuit using transistors for bidirectional driving ofВ DCВ motor.В H-Bridges in ICвЂ™s reduces the drive circuit complexity. The next figure shows the direction of motor control to the input given If you want the o/p to be enabled entirely, then you can connect Enable to VCC and only two pins needed from the controller to make the motor work. Three pins are needed for interfacing a DC motor (A, B, Enable). This chip is designed to control 2 DC motors. A very easy and safe is to use favorite L293DВ chips. As the MCUs PORT is not powerful enough to drive DC motors directly, so we need some drivers. You can reverse the direction of rotation by reversing the polarity of the input. When connected with the power supply the shaft rotates. GearвЂ™s reduce the speed of the motorВ and increases the torque.Д¬hoosing aВ DCВ MotorВ depends upon the application.

Gear reduction is the standard method by which aВ motorВ is made meaningful. A typicalВ DCВ motorВ operates at speeds that are far too high speed to be useful and torque that is far too low. DCВ Motors are small, inexpensive and powerful motors used widely in robotics for their small size and high energy out. For the sake of simplicity, we will learn a way to interface DC motor and not controlling its speed. This tutorial will aim at interfacing a DC geared motor with the ever-popular ATMEGA series.
