Abstract: The brushless DC electric motor comprises, a rotor including a shaft and a permanent magnet fixed on said rotor shaft, stator including a winding in the shape of a hollow cylinder and composed of a plurality of rhombic single coils made of flat wire. The single coils overlap each other in an imbricated manner, wherein the single coils are performed to form an offset at least in the region of two opposite corners. The winding have legs, wherein half of the legs are located in a first radius and half of the legs are located in a second radius. The motor further comprises a housing having two end plates and supporting said rotor and stator.
