The Full-Bridge (H-Bridge) is the most popular driver circuit to control brushed DC motors. The main advantage of a full bridge driver is the ability to change the rotation direction of the motor, without manually reversing the supply wires. I’ve already published the Half-bridge and H-bridge driver circuits before; however, I was receiving many requests and comments for a standalone H-Bridge driver to control the DC motors, without using any external board or a controller. Therefore, I introduced a cheap, compact, and standalone H-Bridge DC motor driver that can be embedded in a variety of mechatronic devices. A cheap ATTiny13 microcontroller controls everything and I used the Arduino IDE to write the microcontroller code. All components, except for the connectors, are SMD. The motor can be controlled in three modes: Forward, Stop, and Reverse. The user can adjust the rotation speed of the motor separately in the forward or reverse direction, using two panel-mounting potentiometers. The low ON-Resistance of the Mosfets allows you to use this circuit in high currents. To design the schematic and PCB, I used Altium Designer 22. The fast component search engine (octopart) allowed me to quickly collect the components’ data and generate the BOM as well. To get high-quality fabricated boards, I sent the Gerber files to PCBWay. To test the driver board, I disassembled an electric toy car and used its powerful 775 DC motor (plus the gearbox). It’s a cool experience, just build one and have fun!

Introduction ---------------- Hi Friends, I am a newcomer. I try to make 750w DC 24V DC motor speed control. At my project i use TL494 ( ka7500) for control the motor, the current increase by 3 mosfet IRF75n75 ( IFR3205) you can use the biger mosfet for get big power. At this video i show you how to i make it. I don't have the big motor so i use 288W 24V 775 motor for test. You can see the result on my video. The circuit run very well. The total cost of the project is around $10 - $15. Step 1 Hardware Requirement You can see all of my project but i will show again Step 2 Make the PCB You can make the PCB use iron method. I have post the Shematic and PCB file. Please download bellow. Or you can order PCB online like me, i order PCB online from JLCPCB.COM. Their price is very low only 2$/10PCB with high quality. I order PCB from their lot of time. You can try. Look the PCB i had order, what do you think about that ? Step 3 Make the PCB The Schematic and layout file. you can download PDF file below and make it at home by yourself. Step 3 Finsh and Get Big Motor Controler I am a newcomer and this is the fist time i post on this forums. If i have any mistake please comment below i will try to fix in the next project. I want to share you all of thing i know. If you have any question for my project, please comment below i will help you. You can find more project about electrical on my youtube channel: https://www.youtube.com/c/LongTechnical Thank you very much 750W_DC_Motor_Controller_TOP PCB.pdf 750W_DC_Motor_Controller_SCH.pdf 750W_DC_Motor_Controller_PCB.pdf
infrared signal is used as the "trigger" for the operation of dc motors(or any other appropriate devices eg:LEDs). i have used the arduino uno as the microcontroller as it simply does the job!also it's cheap too!! future application will ultimately lead to IR controlled robot,and perhaps controlling of human mind using nothing but a simple remote control and interfacing hardware with electrodes,so that the physically disabled can attain normal "motor" functions.thanks.
