Abstract
Permanent magnet blocks fixed on sidewall evenly along circle constitutes main pole. Rotor is composed of end cover and connected bearing as well as pole of permanent magnet. Number of magnetic yoke piled from U type silicon steel sheets is corresponding to number of number of magnetic pole. Yokes distributed along cycle and embedded in bracket constitute U type closed magnetic circuit. Concentrating winding is enwound on U type slot constitutes armature winding. Bracket fixed on axis, winding and magnetic yoke are as stator. In the invention each phase is independent, thus any number of phase can be made. Stator tooth space is perpendicular to armature coil. Thus, size of stator and energized winding are not restricted each other. Radial magnetization of permanent magnet is changed to axial direction magnetization so that number of permanent magnet blocks is reduced to half.
Description
Technical field
The invention belongs to the magneto technical field, specifically, it relates to a kind of horizontal magnetic field motor of permanent magnet axial magnetized, and this motor is particularly useful for the direct driving on electric motor car and naval vessel.
Background technology
In the prior art, common magneto since stator (or rotor) tooth and groove on same cross section, its size is restricted mutually, and motor output torque is restricted.For this reason, De Guo professor H.Weh has invented permanent-magnetic motor with transverse magnetic field.The stator teeth groove structure of this motor and armature coil are vertical mutually on the locus, and the main flux in the motor is along the axial circulation of motor, thereby stator dimensions and hot-wire coil is big or small separate, can obtain higher torque and power density.On this basis, professor G.Henneberger of Germany has designed the flat magnetic field structure permanent-magnetic motor with transverse magnetic field (G.Henneberger of monolateral stator, M.Bork.Development of a New Transverse FluxMotor.New Topologies for Permanent Magnet Machines (Digest no:1997/090), 1997, (1): 1-6.).Permanent magnet is attached to rotor surface equably in this motor, and adjacent permanent magnet is magnetized into different polarity respectively.The stator core module of U-shaped is evenly distributed on the whole circumference with the distance of multiple pole span, the permanent magnet polarity of two tooth portion correspondence is opposite, and the auxiliary stator magnetic circuit that placement is made by soft iron material between two adjacent stator cores, form closed magnetic loop, to reduce the influence of contiguous pole pair work main pole.But this electric machine structure complexity is processed very difficultly, and in order to reduce leakage field, is attached between the adjacent vertically permanent magnet of rotor surface and need leaves enough spacings, and axial dimension is bigger.Therefore, this motor is in the middle low power field, and there is very big limitation in the occasion that particularly requires thin type to install, is difficult to extensive use.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned motor, a kind of permanent-magnetic motor with transverse magnetic field is provided, this motor can shorten axial dimension greatly, and can increase the effective area of air gap when small-power, improves power of motor density, its structural manufacturing process is simple relatively, torque density is big, and stator coil is installed easily and do not had the end loss, and is every independent fully mutually, there is not electromagnetic coupled each other, can high torque (HT) and efficient operation in the rotating speed of broadness and power bracket.
For achieving the above object, a kind of horizontal magnetic field motor provided by the invention, comprise axle, bearing, permanent magnet pole, silicon steel sheet yoke, armature winding and shell, it is characterized in that: permanent magnet evenly distributes to be fixed on the shell abutment wall along circumference and constitutes main pole, the end cap of shell links to each other with bearing, forms rotor jointly with permanent magnet pole; The grouping of U-shaped silicon steel sheet laminates and the corresponding yoke of motor number of pole-pairs, be uniformly distributed along the circumference, by embedding on support mutually, constitute the U-shaped closed magnetic circuit, ceoncentrically wound coil is wound on and constitutes armature winding in the U-lag, support is fixedlyed connected with axle, they with armature winding and silicon steel sheet yoke as motor stator; Armature winding is drawn in the middle of the bearing of hollow respectively.
Each is separate fully mutually among the present invention, thereby easily makes heterogeneous arbitrarily.The stator teeth groove structure of this motor is vertical mutually on the locus with armature coil, thereby stator dimensions and hot-wire coil can not be restricted mutually, can choose arbitrarily within the specific limits.It is axial magnetized that the present invention changes the permanent magnet diametrical magnetization, and every phase permanent magnet blocks number is reduced by half.The silicon steel sheet that constitutes yoke among the present invention only need be fixed on the support simply, and the bindiny mechanism that need not assist between the homophase permanent magnet, has saved the space greatly, makes torque density bigger.

Embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing:
As shown in Figure 1, the present invention includes axle 1, bearing 2 and 12, support 3, permanent magnet pole 6, armature winding 7, silicon steel sheet yoke 8, shell 5, shell 5 comprise abutment wall 9 and end cap 11.Bearing 2 and 12 is enclosed within on the axle 1, and permanent magnet pole 6 is bonded on the abutment wall 9, and end cap 11 links to each other with 12 with bearing 2, and forms rotors jointly with permanent magnet pole 6; Armature winding 7, silicon steel sheet yoke 8, support 3 are fixedlyed connected with axle 1, as motor stator.Lead-out wire 4, tapping lead-in wire links to each other from the open-cycle controller that the hollow parts of axle 1 is drawn outside the machine with other joins.Controller can adopt traditional approach, also can adopt advanced DSP technique construction.
Figure 2 shows that the structure of a phase silicon steel sheet yoke 8 and armature winding 7, yoke becomes U-shaped, evenly distributes along circumference, is embedded on the support by the U-shaped silicon steel plate stacking fixedly to form together, and ceoncentrically wound coil constitutes armature winding in U-lag.
Figure 3 shows that the structure of abutment wall 9 and permanent magnet pole 6, permanent magnet pole 6 bonds together with abutment wall 9.In the implementation process, can be divided into some groups to magnetic pole along circumference, each several part can be combined the formation circle distribution when needing only last the installation; Certainly, also can adopt other version to be guaranteed.
The essential characteristic that the motor of said structure has is: the U-shaped yoke and the armature winding of motor are orthogonal on the locus, and permanent magnet pole is by axial magnetized.
The present invention also can the position near permanent magnet pole be provided with hall position sensor 10 on the silicon steel sheet yoke being positioned at, and motor is carried out closed-loop control.Wherein position transducer also can adopt other modes, as photoelectric encoder, resolver etc., as long as can detect motor rotor position delicately.
