| Scientists and engineers at the South Ural State University Polytechnic Institute of Technology in Russia used 3D printing technology to develop a brushless motor made of light metal alloy coils that can be used in unmanned aircraft and quadcopter aircraft. The motor is currently being patented.  One of the most crucial functions of a drone is its brushless motor, which uses a permanent magnet system on its rotor (rotating part) and stator (stationary part), and the computer charges the electromagnet and generates motion. 'Today all UAVs, quadcopter and electric helicopters use this type of motor as their primary motor drive. The problem now is the increasing power of the machine and its feasibility in manned aviation.' Polytechnic Aircraft and Automation Department Associate Professor Viktor Fyodorov said. However, a Russian team of scientists broke through this power barrier by developing a motor with 3 kW and an active system of about 750. Manufacturers of production motors said the motor was highly reliable because it contained only two components, the rotor and the stator, This makes it less likely to fail, having more moving components than a piston engine.In addition, the combination of a motor and an efficient electrical energy source increases performance and reduces environmental impact. It is estimated that by 2018 consumer unmanned aircraft shipments will reach 13 million units, the company has a great market opportunity, for a variety of UAVs to provide new parts. In addition to the increased sales of commercial UAVs, the military is increasingly using drones for surveillance and other tasks, such as the US marines, where 3D printing has been heavily used to develop new military UAVs.
