IF the motor is connected to the ESC, and you have not yet gone through the full setup procedure, the ESC may be "almost" making the motor run... Since modern speed controls use high frequency pulses to control motor speed, they make the motor "sing" and near stall speeds (pulses to motor, but not enough for it to start turning)...
Go through the setup process CAREFULLY, so that the neutral setting is correct -- it should be quiet, but may "sing" as you just barely start to apply throttle....
