Hi, It has been a while, but maybe some people can remember me from the T053 (T-34/85 tank). I was always fascinated by the working principles of an ESC. For a long time my idea was to build one by my self.
Finally I have build a speed controller for a robot project. It's based at the OSMC H-bridge (http://www.robotpower.com/products/osmc_info.html) I've build 2 of these boards(single layer design). For the T053 I've bought in the past several ESC's from Anvilus Machine works. (with 4 automotive relais and 2 solid state relays). Because the microchip used on the anvilus ESC had all the functions I need, (RC input, channel mixing, motor direction and speed (PWM) as output) I could reuse the controller to drive the boards. So I've made a 3th PCB for the micro controller. The result is awesome. I've proportional speed, and I could do perfect skid steering with my weight on the robot. The robot has 350W geared motors (M01 motor). The price was around €50 (65$) per board, and the PCB with the micro controller was about €15 (20$). The total cost was less then 150$ for a 24V 160A ESC which is relative cheap. Much cheaper then the equally stuf you can find at RobotMarketPlace.com Watch the pictures. I hope this helps a bit. I can always give more information or share some files. I'm still planning on rebuilding my T053 (T34/85 tank) in steel, but the university is taking to much time now. But definatly this ESC come's in my tank :D Greetings Sam D'Haene Belgium <https://lh4.googleusercontent.com/-m41lg938IC0/UDifFMfzF1I/AAAAAAAAAAM/G7-MUG5KZj0/s1600/IMG_3420.JPG> <https://lh6.googleusercontent.com/-JpKzW7uXlq0/UDifI3SiVNI/AAAAAAAAAAk/VQXco-grVLU/s1600/IMG_3423.JPG> <https://lh5.googleusercontent.com/-aAE99y9eTa8/UDifGOzIB_I/AAAAAAAAAAU/Ng3ZqXAHNt4/s1600/IMG_3422.JPG> <https://lh3.googleusercontent.com/-CWT6VeXVQc8/UDifHI2OISI/AAAAAAAAAAc/f-KPJBkIQCA/s1600/IMG_3421.JPG> -- You are currently subscribed to the "R/C Tank Combat" group.
