Due to the weight-sensitivity of aircraft, electric motors are chosen largely based on their power to weight ratio. PMAC (PMSM) and BLDC motors have the highest power/weight. Low-power brushed DC PM motors are also favored for use on ultralight aircraft because the motor and controller are relatively inexpensive.
