Initial Motor Testing
So some exciting news: the motors and ESCs from Singapore have finally arrived! We have hooked them up and tested their speed/current characteristic using a 3A power supply set to 11.1V, a 50Hz PWM (Period of 20000 at 1MHz) signal from the MaEvArM, and the tri-blade rotors. Our initial test results and some pictures/video are below!

Hello
ReplyDeleteDo you have any idea if tri blade have less vibration. And wat is the advantage of the tri. I begin to construct a Tri copter ;-)
Thanks a lot.
Ghis
what happens if i give a higher pwm pulse to ESC !!
ReplyDeletewill the motor maintain same higher speed or will it stop !!
Does anyone have any conclusions on this? Is a tri-blade or a regular dual blade setup more efficient or cause less vibration?
