OK, little miffed right now. How come none of you geniuses pointed out that these drone motors are 3-phase? That ESC is for regular single-phase motors (or wasn't that obvious).
I'll have all of you know I've never actually built a drone before so I don't appreciate being made look an idiot (however it probably makes a kick-*** 8 channel single-pase motor control board...once its fully designed/troubleshot). Ok so little angry now about the possibility of having to use 6 MOSFET's to control a single motor (how the HELL did someone come up with the idea of using a 3-phase motor for these toys...what was it some CAD/CAM guy...and what i the whole difficulty with brushes anyways?). How is this for an idea of how to use 3 MOSFET's to control one of these drone motors? I figure that its the voltage that the motor "sees", I can feed it a 50% PWM signal that my motors will think is zero volts (silly things). Then I can go down to 0% PWM for the negative voltage eliminating the need for the additional 3 MOSFETs. Run 100% for max positive voltage. Impressed with this way of using EMF blowback for controlling the motors though. I went to Digikey/Microchip to get the low-down on brushless motor control and read up on back EMF. However I'm dreaming that I'll just use my gyro package to restart the motors in case of shut down, the main CPU I mean. Gosh, I can see why you guys just talk about this stuff. Its fun and relaxing. *innocent smile* Thoughts? About the technology I mean.
