Product Description

This brushless motor powers quadcopters and similar multicopters. Designed for an 11.1 V battery voltage, it produces up to 1250 g of thrust, enabling the stable flight of medium-weight aircraft.

The motor requires an electronic speed controller (ESC), which regulates the rotational speed using a control signal from the flight controller. Counterclockwise rotation is required to compensate for reactive torque in symmetrical four-propeller configurations; without the correct motor arrangement, uncontrollable torque will occur. A current draw of up to 15 A requires an ESC with the appropriate current rating.

The motor is used in compact multicopters that perform stabilized aerial photography or transport payloads weighing up to a few hundred grams. With a flight weight in the range of 900 to 1200 g, an aircraft equipped with four such motors can be operated.

A flight controller that outputs PWM or digital control signals is required for operation. The appropriate ESC must be rated for at least 15 A. A stable 3-cell battery with sufficient discharge current capability is also required; in addition, all four motors must have very similar specifications to achieve balanced flight.
