So, this is the part everyone has been waiting for. Franken Pump drinks its first blood. And by blood I mean.... wait, Frankenstein doesn't drink blood... Anyways! Horrible humor aside.. The operation of this pump is exciting! It's probably...
On this video I do a quick introduction to some of the Power PACk boards and how they can drive a small aerial vehicle motor. In this case, the motor was taken to 2600 Hz at 26V and 3.3A or so, which is in the 85W worth of input power. How much power...
Size 50mm square and 58mm round On board absolute magnetic encoder is either MA730, MA702, AS5147 or AS5047 There are others in this range. Connectors clockwise from the top BLDC motor connectors & Power In/OutExternal Motor TempqwiicUSBEncoder SPIFan...
Outputs Generate step/dir for controlling a stepper motor, or generate PWM/dir for controlling a BLDC motor or standard DC motorFor the prototype, the current motor is a stepper. The end goal is to drive the BLDC motor. Software generates a trigger,...
So I'm looking for where I misplaced my tin foil box, and I see something in the bag of TCT360 goodies I got months ago:It's a peek print on a metal ball chain! And, conveniently enough, it's the size I've been using for the current Tetrinsic redesign....
So I've looked into the TC358870XBG and it seems that 2 I2C pins, 1 reset pin, 1 clock pin and an INT pin is needed. One probably could make a circuit that generated the clock instead of the MCU, but a free pin is cheaper than that. The main issue...
I think part of the reason that I'm still cautious with #Tetrinsic [gd0041] -- even though I've got a potentially wearable form factor concept now -- is because a solution has not been computed for Tetent Tiny and #Tetent TestCut [gd0139] is...
Today I accomplished two main things. The first was quite simple. I was able to get the gate driver IC's mounted to the SOIC-8 to DIP-8 breakout boards from sparkfun. The second was to determine where to place the hall effect sensors to meet the needs...
So you've made it this far with me. It's time we assemble the beast and bring Franken pump to life! This was a very straight forward assembly almost boring perhaps. Surprisingly there were absolutely no major issues with my designs and subsequently...
So here's something the average build does not have: A thread running in the background continuously checking the integrity of the flash memory! So while your high performance powertrain is crunching numbers, running a 30kHz control loop, communications,...
Fresh merge from VESC repository: https://github.com/vedderb/bldc/pull/88 Last week we provided the code to handle 2 dangerous failure modes: Sensor/wiring damageFault to ground If a current sensor is damaged, the FOC will run out of control, with dangerous...
When the nozzle puts the SMD parts down, the part height actually has some tolerance associated with it. This looks to be between 0.1mm and 0.5mm of deviation I will need to account for. I do have fine control over the Z axis with my chosen...
Ive been running into this issue when trying to run the motor. The company which sells the motor driver shield for the Arduino has a demo code uploaded on github, so i copied it and put it on the Arduino. The shield also had to be adjusted for this type...
In S-drive controller I used a 10-bit encoder. The encoder is connected to the output shaft of the BLDC motor. There is no encoder on the output shaft after the reducer. That means that one revolution of BLDC is equal to 1024 ticks of the encoder. One...
