A Hard disk drive motor has more coils than this simple triphased motor. Practically I have found 24 stable positions. The basis sequence of 6 positions is thus repeated 4 times. And 24 is a very convenient number for a clock !As we have 24 stable...
I started to look more closely at the centripetal force equation, since I've been wary of raising the Gyrofan speed higher with its full mass, as I didn't know exactly how much force was being generated. I'd like to ramp the thing up to get appreciable...
Rotating polygon laser scanners need to keep track of the angular position of theprism or mirror.In an earlier version of Hexastorm, this was achieved with a Sharp A160 polygonmotor. This board has a NIBC3111 chip. Motor speed could becontrolled by sending...
A Connector board is used to connect the S-drive BLDC driver to the 24 power supply and to the teensy microcontroller. They are designed to be stacked one on one with brass spacers.
Pricing all the parts for 2 bldc motors, two vesc controllers, charger, etc for what I wanted to build here put me at about $400. That was a bit high...I have revised the plan. Do what I can using what I got on hand, and spend less than $100...
Detailed technical description: (ax1 is the base rotation, ax2 the joint just above it, and so on...) For control I use 5X Teensy 3.2 microcontrollers, they are connected together into a single CAN network, (Odrive is also on...
The focus of this project is a very low cost robotic platform that provides a test bed for a new model of machine cognition. A purpose built micro cluster serves as the 'brain' and the BigSack deep K/V store was optimized for cluster operation. The Robot...
A picture story:I have completed the building of my first motor driver board. This is a prototype so it has been constructed on a perf board protyping board that I bought at Fry's electronics. This is not meant to be a flying prototype just a test bed...
This project has six systems that make up the cooling pack system. Power Management: Charger/Li-ion cell balancer.Dual battery pack management.(implemented in later models)Li-ion charger and DC/solar power input.TI MSP430 microcontroller power control...
