This is a brushless (BLDC) outrunner motor specifically made for quadcopters and multirotors. It is a 1400kV motor. It provides high performance, super power and brilliant efficiency.
D2826-10 is a brushless motor with a KV rating of 1400. Brushless motors are synchronous motors that are powered by a DC electric source via an integrated inverter/switching power supply, which produces an AC electric signal to drive the motor. In this context, AC, alternating current, does not imply a sinusoidal waveform, but rather a bi-directional current with no restriction on waveform.
Note: D2826-1400kV is a Short shaft BLDC motor.
