BLDC / L293D / Arduino

This is the lab animal for Portland State University's EE410/510, Electric Vehicle Technology, Lab 6. It's a brushless DC motor that was the spindle motor from an old CD-ROM drive. It's being driven by an Arduino Mega, through a pair of L293D driver chips on a modified Adafruit Motor Shield. The resistors (5 ohms, 2W on each leg) are in series with the windings to keep the current down to a level the L293D can handle, and to keep from inadvertently smoking the windings. The BLDC motor has three Hall sensors, with an LM339 comparator to drive Arduino inputs. When the sensors change, Arduino switches the winding drive accordingly.

don't need schematic just the source code.

@veerendra2020 you will not build the ESC any cheaper than China manufacturers...

Schematic? :D

Hi! I'm a novice and I'm trying to drive a motor savaged from a dvd drive.. could you please share the circuit and the code. Thanks :)

[veerendra2020]

Nice....Can RC BLDC motor controlled with this..? I mean eliminating the expensive ESC from RC plane...

Please post the complete project with circuit diagram....

Its help-full to all.........

Very cool. Thank you for the information also :)
