Abstract
The motor comprises a rotor 2 in magnetic material with a plurality of angularly equidistant lobes or poles 2a and one stator 4 with a pack of laminations 5 presenting a central opening 6 in which a plurality of poles 7 extends, protruding radially towards the rotor 2 and angularly equidistant along a circumference and each bearing a respective winding W1, W2, W3 appertaining to a different motor phase. The number of stator 4 poles 7 is different from the number of the poles or lobes 2a of the rotor 2. The pack of stator laminations 5 has an external polygonal profile and in one of its angle parts 5a has at least one seat 9a, which is adjacent to at least two stator poles 7 and housed in which are protective thermal sensors 12 suitable for providing an electric signal when the heat developed by the currents flowing during operation of the stator winding phases W1, W2, W3 exceeds a predetermined value. <IMAGE>
