Embodiment Construction
[0116] figure 1 The device 1 depicted in includes a magnet frame 3 extending radially along the axis of rotation X of the rotor, which frame is preferably formed of stacks of laminations stacked along the axis X, the laminations being considered in this example as complete identical and exactly overlapping.
[0117] The rotor 1 comprises a plurality of permanent magnets 7 placed in respective accommodation areas 5 of the magnetic rotor frame 3 so that two consecutive magnets 7 have the same polarity on faces facing each other.
[0118] The rotor frame 3 is mounted on a support body 2 , which is, in the example considered, a shaft made of a magnetic material such as steel.
[0119] The rotor frame 3 has a central opening 4 for mounting it on the shaft 2 . D The central opening 4 has a diameter D of, for example, between 40 mm and 50 mm.
[0120] Furthermore, the central opening 4 has an anti-rotation projection 11 which engages in a corresponding slot in the shaft.
