<p>The invention relates to a commuted reluctance motor, with internal rotor self-ventilation. According to the invention, the motor consists of a stator () made of electrotechnical steel sheets forming eight stator poles and an electric circuit () consisting of four phases, each phase comprising two coils wound around the salient poles located diametrically opposed, and a rotor () located inside the stator (), also made of electrotechnical steel sheets, between every two consecutive salient poles of the rotor () there being located some elements () made of non-magnetic material, uniting the margins of the poles at the two extreme ends of the rotor (), said elements () being arranged slantwise, being twisted in such a manner as to ensure a perfect alignment with the margins of the rotor poles, at the extremities of rotor (), said elements () acting as an internal fan which, together with the rotor () movement ventilates the stator windings, forcing the warm air around the windings to get out, being replaced with cold air from outside.</p> |
