Equal pole double-section reluctance generator

Abstract

The invention relates to an equal pole single-section and double-section reluctance generator, which comprises two sections of stators and two sections of rotors, wherein the two sections of stators and the two sections of rotors are respectively of a salient pole structure. A stator pole is provided with armature concentrated wildings or layer windings, and stator windings can form multigroup reversed polarity series connection or like polarity parallel connection of each-phase winding. The rotors are provided with rotary poles with the same pole number as the stators, and each pole is a permanent magnet surface-mounted electric excitation hybrid pole or a permanent magnet built-in radial pole. The number of poles of the stators is equal to the number of poles of the rotors, and the stators and the rotors are respectively composed of even number of poles, namely pair poles. The length of the two sections of stators and the length of the two sections of rotors are equal, iron core poles of the two sections of rotors align with each other, and iron core poles of the two sections of stators are different from each other by 1 / 2 polar distance angle. Each rotor can be of an inner rotor type and an outer rotor type. When an outer armature is used, each rotor is a permanent magnet surface-mounted electric excitation hybrid inner rotor or a permanent magnet built-in radial inner rotor; and when an inner armature is used, each rotor is a permanent magnet surface-mounted electric excitation hybrid outer rotor or a permanent magnet built-in radial outer rotor. The equal pole single-section and double-section reluctance generator can be applied to the novel technical field of various frequency conversion speed change, frequency conversion voltage transformation and frequency conversion power transformation.

Description

technical field [0001] The invention belongs to the technical field of generators, in particular to an improved equal-pole double-segment reluctance generator. Background technique [0002] In the existing switched reluctance motor technology, due to the difference in the double salient pole magnetic pole structure of the switched reluctance motor, that is, the salient poles of the stator and rotor are not equal, the number of salient poles of the stator is greater than the number of salient poles of the rotor, and switch control is also required in the power generation state The excitation current of the sub-winding and the time to control its excitation control angle increase the manufacturing cost and operating cost by 1 / 3-2 / 5, and the excitation method is a phase-by-phase excitation method, that is, the switched reluctance motor is reversible Its control is more complicated when the state is used as power generation. When the motor rotates once, the power tube is electro...

Problems solved by technology

However, the effect is not perfect when the power is medium, the number of poles is small, and the operation is at low speed, especially when the stator and rotor equipolar technology is adopted. Although the power output is increased, the magnetic poles of the stator and rotor equipolar technology are equivalent to the stator and rotor N, S, The N and S magnetic circuits are in the closed state of the static magnetic poles, but the static magnetic resistance is relatively large, resulting in large starting resistance for power generation, large low-speed noise, and there are also shortcomings in mechanical resonance vibration and magnetic pole resonance noise caused by magnetic resonance.
