Abstract
The present invention relates to a magnetism-collecting transverse magnetic field motor which comprises a shell body, a stator core, a stator annular coil, a rotor core, a permanent magnet pole and a rotation shaft. The present invention is characterized in that a transverse concave stator is composed of an outer stator core, an inner stator core and an excessive core in each group stator, wherein the inner and the outer stator cores are interlaced along an axial cross section, an N phase stator is correspondingly interlaced with 1/N polar pitches, and the outer stator core, the inner stator core and the excessive core are respectively formed by overlapping core punching sheets; the stator is fixed by an end plate on a machine seat, rotor spokes are arranged on the rotation shaft, rotor excitation rings which are formed by alternately connecting permanent magnets and the cores are arranged on the rotor spokes, and the magnet poles of the adjacent permanent magnets on the rotor excitation rings are opposite. The present invention has the advantages that a combined stator structure is adopted, the magnetism-collecting transverse magnetic field motor having each power class with different number of poles and phase numbers is composed of the permanent magnets and the core punching sheets, so the air gap flux density is effectively improved, an output torque and the output power are enhanced, a structure is simplified, and the cost is reduced.
Description
Technical field
The present invention relates to a kind of horizontal magnetic field motor, particularly a kind of focused transverse magnetic field motor.
Background technology
But horizontal magnetic field motor is owing to have not coupling independent analysis and control between each phase at present, and every phase only needs one group of winding, winding constitutes simple and convenient, rotor is made of the structure of poly-magnetic iron-core lamination and permanent magnet, can produce very big air gap flux density, design freedom is big, can change magnetic circuit size and coil window thereby developed and application as required, but its stator employing U-shaped or C shape are applicable to the core construction of major diameter horizontal magnetic field motor, are not suitable for the focused transverse magnetic field motor of minor diameter.
Summary of the invention
The objective of the invention is to solve the stator employing U-shaped of horizontal magnetic field motor in the prior art or the core construction that C shape is applicable to the major diameter motor, be not suitable for the problem of the focused transverse magnetic field motor of minor diameter.The present invention designs focused transverse magnetic field motor, comprise housing, stator core, the stator annulus, rotor core, permanent magnet pole, rotating shaft, it is characterized in that: every group of stator is by external stator core, inner-stator iron core and excessive iron core constitute a horizontal concave shape stator, external stator core and inner-stator iron core cross section vertically is staggered, N phase stator 1/N the pole span that stagger relatively, N is the number of phases of motor, external stator core, inner-stator iron core, excessively iron core constitutes by the core stamping closed assembly, the length of external stator core and inner-stator iron core, highly identical, stator is fixed by the end plate on the support, rotor spoke is arranged in the rotating shaft, the excitatory ring of rotor that has permanent magnet and rotor core alternately to join and constitute on the rotor spoke, permanent magnet pole adjacent on the excitatory ring of rotor is relative.Advantage of the present invention is to adopt combined stator structure, form the focused transverse magnetic field motor of the various power grades of the different numbers of phases of different poles number with the rotor that constitutes by permanent magnet and iron-core lamination, magnetic flux in the iron core is assembled to reach the effect of poly-magnetic, effectively improve air gap flux density, improve the output torque and the power output of focused transverse magnetic field motor, and simplified stator structure and manufacturing process, reduced production cost.
