Operating principle and design features

The BKM 340 motor is a brushless motor. It works on the principle of a synchronous electric machine. The current creates a magnetic field in the stator windings. It interacts with the permanent magnets of the rotor. A torque arises that rotates the shaft. Outrunner design provides high torque.

Russian engineers have created an engine with improved performance. It has less weight with higher efficiency. This allows you to install more payload on the drone. Your quadcopter will have an advantage in carrying capacity. The motor is part of a new line of domestic power plants.
