Hi all, So I'm trying to build a simple quadcopter that uses an analog circuit to balance the copter in the air, as part of an analog electronics course. As part of this project we bought replacement motors for the Phantom 2, specifically the 2212 motors with 920 kv. While we have been able to generate the 3phase wave needed to drive the motor, it does not respond to our signal. My guess is we need to run more current through the motor, so we will be getting power opamps soon to supply up to 3 amps, but if anyone has specific details on what voltages or currents we need to drive the motor, I would really appreciate it. Thanks.
