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 Flux Motor.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, permanent-magnetic motor with transverse magnetic field provided by the invention, comprise axle, bearing, permanent magnet pole, stator silicon steel sheet yoke, armature winding and shell, it is characterized in that: permanent magnet pole evenly distributes to be fixed on the shell abutment wall along circumference and constitutes main pole, produces the main field of motor; The direction of magnetization of permanent magnet pole is that axially permanent magnet pole is held in the mouth in stator silicon steel sheet yoke and rotated, and air gap is between stator silicon steel sheet yoke and permanent magnet pole, and the direction of air gap is axial; 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 stator silicon steel sheet of motor number of pole-pairs yoke; Stator silicon steel sheet yoke evenly distributes along circumference, by embedding on support mutually; Permanent magnet pole, axial air-gap and stator silicon steel sheet yoke constitute closed magnetic circuit; Ceoncentrically wound coil is wound in the stator silicon steel sheet yoke and constitutes armature winding, and support is fixedlyed connected with axle, they with armature winding and stator silicon steel sheet yoke as motor stator; Each phase 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.
