Switched reluctance motor of rechargeable ship and switched reluctance drive device

Abstract

The invention provides a switched reluctance motor of a rechargeable ship and a switched reluctance drive device. The switched reluctance motor comprises a housing, broad stator tooth poles, narrow stator tooth poles, stator auxiliary slots I, stator auxiliary slots II, rotor tooth poles, rotor auxiliary slots and a rotor main body, wherein six broad stator tooth poles are fixed on the inner wall of the housing at equal distances; six narrow stator tooth poles are arranged on the inner wall of the housing at equal intervals; two stator auxiliary slots I are processed in the outer end of each broad stator tooth pole; two stator auxiliary slots II are processed in the outer end of each narrow stator tooth pole; the six broad stator tooth poles are wound by an A-phase coil, a B-phase coil and a C-phase coil respectively; eight rotor tooth poles are fixed at the outer end of the rotor main body at equal distances; and two rotor auxiliary slots are processed in the outer end of each rotor tooth pole. By the switched reluctance motor of the rechargeable ship, magnetic saturation is prevented, the rotating effect of a rotor is improved, the number of quasi-salient poles is increased, the unilateral deformation is reduced and torque ripples, air pulsation and acoustical power are reduced.

[0002] With the development of electromagnetic technology and power electronics technology, motors have been greatly improved in terms of efficiency and speed regulation performance. On the one hand, it solves the unreliability and safety hazards of brush motor commutation. , flexible control, good speed regulation performance and efficiency. For the existing switched reluctance motor, the stator specifications are the same, which often causes magnetic saturation and affects the rotor rotation effect. The rotor rotation on the existing switched reluctance motor is determined by The excitation magnetic field of the stator is coupled in the salient pole rotor, which is caused by the component of the magnetic pulling force in the tangential direction of the rotor based on the principle of "minimum reluctance". This determines that the reluctance motor has a simple structure, firmness, convenient processing, and low cost. features

However, the salient pole structure of the reluctance motor and its switch control characteristics also make its torque ripple, vibration, and noise a problem that restricts its development
