Technical field
The present invention relates to a kind of rotor for reluctance motor, the reluctance motor with this rotor, motor vehicle and the method for the manufacture of mentioned rotor.Rotor has multiple single lamination of being electrically insulated from each other or rotor pack, and it is stacked into stack of laminations with stacking.
Background technology
For the rotor of reluctance motor from US5, known in 818,140A.Wherein describe a kind of rotor, its stack of laminations is made up of rotor pack, and rotor pack has pressing part.Rotor at this also referred to as being Vagati rotor.Obtain arc strip lamination portion section by pressing part, lamination portion section is used as flux channeled portion section and with for providing mode direct magnetic flux necessary necessary magnetic resistance for rotor.Between each flux channeled portion section, be through the air of pressing part, namely play the nonmagnetic region of magnetic flux lock portion effect.High amount of torque is obtained by the flux channeled portion section of bar shaped.The impedance of stack of laminations due to nonmagnetic region along the direction of q axis, namely magnetic latch direction be less.The flux channeled portion section of bar shaped connects transverse to q Axis Extension and by the pole adjacent in circumferential direction of rotor, i.e. d axis.But, for providing nonmagnetic region or the pressing part for forming flux channeled portion section to result in weakening of the mechanical stability of stack of laminations, make described rotor be not suitable for large rotating speed, especially be not suitable for being greater than the rotating speed of 3000 revs/min.For this reason, the reluctance rotor of described type is not suitable for the rotation speed requirements had in the automotive field of electric driver.
From JP2002095227A, there is known a kind of Vagati rotor, wherein, magnetic flux blocked region is cast with synthetic resin.At this, contiguous flux channeled portion section has trapezoidal vacancy, and when casting, synthetic resin flows in this vacancy equally.Thus, flux channeled portion section is connected with the synthetic resin of sclerosis via dovetail connection subsequently.Therefore, in high-revolving situation, the pulling force flux channeled portion section from the outside caused due to centrifugal force is inwardly transmitted to axle via synthetic resin.That synthetic resin can tear when tensile load in this shortcoming.Vacancy in flux channeled portion section adversely have impact on the efficiency of engine, because hamper magnetic flux.
Summary of the invention
The object of the invention is to, provide a kind of rotor starting described type, it not only can realize high torque (HT) but also realize high rotating speed, thus makes it be particularly suitable as the assembly of the electric drive for motor vehicle.
This object is realized by rotor according to claim 1, reluctance motor according to claim 11, motor vehicle according to claim 12 and method according to claim 13.Favourable improvement project of the present invention is provided by dependent claims.
Rotor according to the present invention is reluctance rotor, and namely rotor arranges and is used for reluctance motor.Therefore, rotor according to the present invention has stack of laminations in known manner, namely by multiple soft magnetism rotor pack be electrically insulated from each other form stacking, rotor pack radially extends away from the rotation of rotor respectively.In other words, rotor pack strings along rotor axis or piles up.Rotor according to the present invention meets the Vagati reluctance rotor (US5,818,140A) described by beginning.Therefore, each layer of stack of laminations has the rotor pack of energy magnetic conduction, wherein forms by such as pressing part the multiple flux channeled portion section being used for magnetic flux.Flux channeled portion section is especially bar shaped and/or two the adjacent in circumferential direction d axis being connected to rotor in known type.Flux channeled portion section is separated from each other respectively by nonmagnetic region, the vacancy namely such as stamped out.Nonmagnetic region is played the effect of magnetic flux locking and is preferably extended between two of rotor adjacent in circumferential direction q axis respectively.Magnetic be especially interpreted as ferromagnetic, preferred soft magnetism at this.Correspondingly, this by non-ferromagnetic for being interpreted as of nonmagnetic or non-magnetic, be non-soft magnetism especially.Nonmagnetic region is filled with air or polymer, especially synthetic resin especially respectively to this.In addition, the metal alloy of non-magnetic can be adopted, preferably there is when less density the aluminium alloy of high-tensile high solidity.
When rotor rotates, centrifugal action is in each flux channeled portion section, and centrifugal force makes the regional of rotor pack away from rotation ground radially outward.But, reduce the mechanical load-bearing capacity of rotor by nonmagnetic region, i.e. such as pressing part.
In order to compensate the mechanical reduction caused owing to arranging nonmagnetic region, what arrange in rotor according to the present invention is, each magnetic flux blocked region of different layers is in turn arranged in the axial direction when being strung by rotor pack, forms space or hoistway respectively on the whole with the magnetic flux blocked region of the mutual correspondence making each layer in stack of laminations.In other words, the vacancy of single lamination can alignedly in turn be arranged in the axial direction, and namely each rotor pack does not have or only mutually torsionally arranges along rotation slightly.Now at least one hoistway, arrange non-magnetic strutting piece respectively, i.e. such as bar.To this, each strutting piece is designed for, and opposing is movably in radial directions to corresponding radial built-in, the adjacent flux channeled portion section of outer support.Therefore, can such as insertion rod in each hoistway, it inwardly extrudes single lamination when rotor rotates rotation.
Describe with beginning, Vagati rotor is connected via dovetail the solution that keeps together unlike, following advantage is had in rotor according to the present invention, strutting piece is not loaded by pulling force when rotor rotates, but pressure must be applied in inner flux channeled portion section by strutting piece.Therefore, the material of strutting piece is compacted and do not expand, and this makes rotor more stable.
In order to derive the power be radially outward applied on strutting piece of strutting piece, propose the improvement project that of rotor is favourable, be furnished with dish at one or two end face side place of the columniform basic configuration of rotor, it is connected with each strutting piece.Such dish can depend on the power ground that is applied on strutting piece and substantially be connected than dovetail well known in the prior art on its thickness with material behavior with therefore depending on the desired maximum (top) speed of such as rotor and mate more simply.
