Scientists and engineers from the Polytechnic Institute of South Ural State University in Russia have 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 patent pending.
One of the drone's most critical features is its brushless motor, which uses a system of permanent magnets on its rotor (the rotating part) and stator (the stationary part). The computer charges the electromagnet and creates motion.
“Today, all drones, quadcopters and electric helicopters use this motor as the main motion drive, the question now is the increasing power of the machine and its feasibility in manned aviation ” said Viktor Fyodorov, associate professor at the Polytechnic Institute of Aircraft and Automation Department.
However, a team of Russian scientists broke through this power barrier and developed a motor with a power of 3 kilowatts and an active system of about 750 grams. Manufacturers who produce the electric motor say it is highly reliable because it contains only two components, the rotor and stator, making it less likely to fail and having more moving components than a piston engine. Additionally, the combination of electric motors and efficient electrical energy sources improves performance and reduces environmental impact.
It is expected that the shipment of consumer drones will reach 13 million units by 2018. Currently, the company has great market opportunities and can provide new components for various drones. Web link
