Yeah you need to look and do some more research micro soldering at home is becoming a thing so parts like he just created are actually shrunk into a tenth of the size of what it is already
@Reneg973 make the chip cylindrical and place it in a compartment slightly extending off the bottom. Due to the size of the chip it would be a very tiny difference. And it could make it flush and simple yet not over heating. THEORETICALLY
@@snek9388FIRST Robotics Competition has a few motors that do this! They're brushless, and you control them over CANbus (usually) but it's that exact idea.
the moving of air from the motor or its moving is enough to cool it. its also not powerful and other drones do the same thing with more powerful components @@Reneg973
Try using a smaller PCB: you are using the soldering method, which forces you to dedicate most of the PCB to connection to cables (and solder points add much weight), but you could use the type of connection used with little LC displays: conductive foam. Your wires would then be a flexible, narrow printed ribbon, the driver's PCB, eight times smaller.
But that's just an H-bridge. It still needs an MCU, at which point you can move the H-bridge to MCU PCB and say that you've saved the weight of the whole ESC
FYI this entire video has some horrific high pitched sound in the background of the video starting from around when the motor starts spinning the first time
If I wanted to make a quad copter drone I would need 4 drive cells? What is the recommended way to chain the drive logic from the main computer to all 4 cells.
Largest issue in these motors is not a driver, but motor design itself. Especially brushes, that are so small that effectively die after 10-15 work hours.
I know you meant Carl, but yeah, it depends on your use case. If what you need is a very tiny motor use coreless motors. They are very efficient for DC motors because the only part that turns is the copper winding, eliminating core losses. Having no iron in the rotor means they are extremely low inertia as well and can spin incredibly fast. I've seen them in sizes down to 4x6 mm.
Sir, how would an h- bridge control motor speed. PWM controllers sre supposed to control the speed of th motor &, of course, a variable dc supply can also control the motor soeed. An h-bridge is used to start or stop & control the direction of motor rotation.
