Abstract

The invention discloses a rotor inner-cooling type pulse generator, and belongs to the technical field of motor rotor cooling. The invention aims to solve the problem that it is difficult to cool therotor due to serious heating of excitation windings of the existing pulse generator. The cooling structure comprises a cooling water outlet section, a cooling inlet section and an internal cooling main body, wherein the internal cooling main body is arranged in a rotor yoke and is close to the excitation windings along the radial direction; the cooling inlet section is introduced from a cavity formed in the end part of the rotating shaft and is communicated with an inlet of the internal cooling main body, and an outlet end of the internal cooling main body is communicated with the cooling water outlet section; the internal cooling main body comprises a plurality of spiral cooling pipes which are evenly distributed in the circumferential direction, the number of the spiral cooling pipes corresponds to the number of the excitation windings, and the positions of the axial center sections of the spiral cooling pipes in the circumferential direction correspond to the center positions of theexcitation windings in the circumferential direction. The pulse generator is effectively cooled, and the discharge capacity of the generator and the repeated discharge frequency of the load can be improved.

Description

Technical field [0001] The invention relates to a rotor internal cooling pulse generator, and belongs to the technical field of motor rotor cooling. Background technique [0002] The pulse generator integrates inertial energy storage, electromechanical energy conversion and power adjustment. It has the comprehensive advantages of "single element", such as high energy density, high power density, suitable for repeated discharge, and flexible pulse waveform adjustment. , Industrial and civilian fields have a wide range of applications. [0003] Compared with traditional iron-core motors, air-core pulse generators ("air-core" that use non-magnetic materials) require higher excitation current, resulting in higher excitation winding losses. The high copper loss of the field winding makes the winding heating problem more prominent, which limits the further improvement of the pulse generator performance. In order to improve the power level, power density, discharge capacity, and repetit...
