So head sinks are needed to cool the circuit. If motors are needed to run with high current then lot of dissipation is there. We can also make a small truth table according to the switching of H-Bridge explained above.Īs already said, H-bridge can be made with the help of trasistors as well as MOSFETs, the only thing is the power handling capacity of the circuit. Similarly, when you switch on low side left and high side right, the current flows in opposite direction and motor rotates in backward direction. rather of being cheap, they only increase the size of the design board, which is somtimes not required so using a small 16 pin IC is preffered for this purpose. H-bridge can also be made with the help of trasistors and MOSFETs etc.
#L293D MOTOR DRIVER CIRCUIT DIAGRAM WIKIPEDIA DRIVERS#
These days many IC manufacturers have H-bridge motor drivers available in the market like L293D is most used H-Bridge driver IC. Usually H-bridge is preffered way of interfacing a DC motor. In this part of tutorial we will learn to interfacing a DC motor with a microcontroller. So you can see DC motors are no less than a stepper motor. keeping track of how many turns are made by your motors etc. For example you can control the speed of motor, you can control the direction of rotation, you can also do encoding of the rotation made by DC motor i.e. There are many things which you can do with your DC motor when interfaced with a microcontroller. DC motors are always preffered over stepper motors. When it comes to speed, weight, size, cost. And there are always two options in front of the designer whether to use a DC motor or a stepper motor. Whenever a robotics hobbyist talk about making a robot, the first thing comes to his mind is making the robot move on the ground.
