Scientists and engineers at the Polytechnic Institute of Southern Ural State, Russia, used 3D printing technology to develop a brushless motor made of light metal alloy coils that can be used in drones and quadcopters. The motor is currently being patented. One of the most critical functions of the drone is its brushless motor, which uses a permanent magnet system on its rotor (rotating part) and stator (stationary part). The computer charges the electromagnet and produces motion. “Today, all UAVs, quadcopters and electric helicopters use this type of motor as the main motion drive. The problem now is the increasing power of the machine and its feasibility in manned aviation.†Institute of Technology Aircraft and Automation Viktor Fyodorov, associate professor of the department, said. However, a team of Russian scientists broke through this power barrier and developed a motor with 3 kW of power and an active system of approximately 750 grams. The manufacturer of the motor says that the motor is highly reliable because it only contains the rotor and stator components, which makes it less likely to fail and has more moving components than the piston engine. In addition, the combination of motors and high-efficiency electrical energy can improve performance and reduce environmental impact.
