<p>A simple, easy and small shaped brushless electric motor which can be electronically commutated and is able to start regardless to each initial position of its rotor, by which moreover the power can be controlled electronically and the turning speed can be adjusted continuously, comprises a housing (10) of a non¬ magnetic material, within which a shaft (20) is embedded, to which a winding assembly (2) is connected with the possibility of torque transmission, wherein said winding assembly (2) comprises electric conductors (21, 22, 23, 24, 25, 26, 27, 28) which are adapted to cooperate with a magnetic assembly (1) which is firmly attached to said housing (10) and consists of a pre-determined number of magnets (11, 12, 13, 14, 15, 16, 17, 18) which are firmly attached onto at least two discs (101, 102, 103) which are fixed within said housing (10) and in the axial direction spaced apart from each other, and wherein a disc (201, 202) is inserted in each gap between each two neighboring discs (101, 102, 103), which consists of at least two printed conductor layers (2011, 2012; 2021, 2022), each layer (2011, 2012; 2021, 2022) consisting of electric insulating material and is on its each side which is faced towards said magnets (1 1, 12, 13, 14, 15, 16, 17, 18) furnished with mesh- shaped electric conductors (21, 22, 23, 24, 25, 26, 27, 28) formed as a surface layer consisting of electric conductive material.</p> |
