Description

A kind of low coupled double remaining permanent-magnet brushless DC electric machine
Technical field
The present invention relates to a kind of permanent-magnet brushless DC electric machine.
Background technology
Along with further developing of rare earth permanent-magnetic material and electric machine theory, permanent-magnet brushless DC electric machine is widely used in Aeronautics and Astronautics field that system reliability is had relatively high expectations with its high energy product (BH), high-coercive force (Hc) and big residual flux density (Br).Especially in complicacies such as aircraft electric steering engine, engine oil gate controls and do not allow to shut down in the servo system of operation, its reliability design is most important.
The reliability of system depends on the reliability of components and parts; For the failure rate that reduces system or equipment to improve its reliability; Normal redundancy (remaining) designing technique that adopts; Promptly the key position in system increases the element of accomplishing identical function more than the cover, and after this part broke down, system still can operate as normal.More should adopt redundant technique for system or equipment complicacy, that have highly reliable and long-life to require.
The primary structure of permanent-magnet brushless DC electric machine comprises stator core, armature winding, permanent magnet, rotor core and rotating shaft, and wherein stator core is overrided to form by the stator punching of trough of belt, and armature winding is embedded in the stator core slot; Rotor core is overrided to form by lamination, and its axial length is identical with the axial length of stator core, and the permanent magnet that will be tile shape is embedded in the rotor core outer surface, and rotor core is fixed on the machine shaft.
The existing remaining configuration mode of permanent-magnet brushless DC electric machine mainly comprises two kinds of versions of parallel connection and series connection; Wherein, the two remaining permanent-magnet brushless DC electric machines of cascaded structure are to overlap independently stator and the coaxial installation of rotor with two, and two overlap independently armature winding is embedded in two respectively and overlaps independently in the stator slot; The increase of stator and rotor quantity will cause the volume and weight of motor bigger than normal; Complex structure is difficult to coordinate control between remaining, therefore be difficult to be applied to the occasion strict to volume and weight; And the two remaining permanent-magnet brushless DC electric machines of parallel-connection structure only comprise that a cover rotor and two overlaps independently armature winding; Wherein the separate armature winding separate slot of two covers is embedded in the stator slot of motor, its corresponding respectively control system of every cover winding constitutes independently passage.This is simple in structure, between remaining control convenient reduced motor volume greatly because a cover rotor is only arranged, reduced motor weight, thereby obtained using widely in remaining control field.
Yet the two remaining permanent-magnet brushless DC electric machines of parallel-connection structure have increased the uncertainty of system parameter variations, the control performance of severe exacerbation motor because the armature winding juxtaposition spatially that separate slot embeds makes motor produce bigger mutual inductance.Therefore, how to reduce the main difficult problem that the degree of coupling between two remaining permanent-magnet brushless DC electric machines two cover armature winding of parallel-connection structure becomes engineering practice.
