A motor-wheel comprises an axle (1), a rim (2) mounted rotatably about the axle (1), a voltage control unit (32) and an electric motor comprising a stator (4) secured on the axle (1) and provided with a magnetic circuit (5) with electromagnets (6, 7) arranged in two groups, and a rotor (10) connected to the rim (2) and provided with a magnetic circuit (11) with magnetic elements (12), current collectors (8 and 9) and a distributing collector (13). The groups of the electromagnets (6 and 7) are mutually offset so that when the current collecting elements (17, 18 or 19, 20) of the current collector (8 or 9) corresponding to one of the groups of electromagnets (6 or 7) are situated between the plates (14, 15) of the distributing collector (13) the electromagnets (6 or 7) of that group are disconnected from the voltage control unit (32), whereas the electromagnets (7 or 6) of the other group are electrically connected, through a contact element (21), the current collecting elements (19, 20 or 17, 18) and the plates (14, 15) of the distributing collector (13), to the voltage control unit (32) and are magnetically interconnected with the magnetic elements (12) of the rotor, thus providing for rotation of the rim (2), while the axes (43) of the electromagnets (7 or 6) of that said group are situated between the axes (44) of the magnetic elements (12) of the rotor (10). <IMAGE> |
