The invention relates to an electric machine meant for electric bicycle drive. According to the invention, the electric machine, consisting of a stator and a modular rotor, comprises some exterior covers (1), some rotor modules (2) among which non-magnetic separation elements (6, 7, 8) are placed, and which are made of some magnetic elements (3, 4, 5) made of sheets, which close the magnetic field path within the electric machine rotor and ensure the assembling of the wheel spokes (10, 11, 12) fixed with a spring lock (13) and the stator consists of a magnetic core (14) and a three-phase winding (15), the rotor construction on axial and transverse direction allowing a variation of the machine reluctance as well as simple and fast maintenance operations. |
