The novel structure makes the novel motor satisfy some requirements of high accuracy and high performance.
Description
The utility model belongs to magneto and slotless electric machines.
Gong Ying motor generally has been the groove motor in the market.Such as in the direct current machine class, 4 serial DC motor of AEG company, the IGG5 series DC motor of Siemens Company, Z4, the Z2 series DC motor that China is existing etc.In the alternating current machine class, Y series, JO2 series asynchronous motor, the small-sized three-phase synchronous generator of T2 series etc.These motors all have groove on iron core, winding is embedded in groove.Most of as common driving class motor or general generator.But, to some high accuracy, high-performance and require the little direct current tachogenerator of voltage ripple; The wide range speed control motor that electrical time constant is little, the moment ripple is little and require commutation ability, high-speed electric expreess locomotive that operating characteristic is good is with there being the groove motor often can not realize.
Traditional direct current machine and ac synchronous motor are wound with an excitation winding on its magnetic pole.This winding and armature winding series, parallel or self are independently switched on.The magnetic pole that has excitation winding occupies bigger a part of space in motor, the weight of motor and external diameter are strengthened, and heating increases, and heat radiation, the difficulty of ventilating are to efficiency of motor, stock utilization, overload magnification, all have in various degree an influence.
The utility model is exactly in view of the problems referred to above that exist in common electric machine, and for effectively addressing these problems.
Therefore the purpose of this utility model is exactly to change the structural shape of motor and process and its performance index are increased significantly.
For the permanent magnetism slotless electric machines of the present utility model of above-mentioned purpose promptly is that magnetic pole to motor adopts the permanent magnetic steel of high-coercive force, high energy product, high remanent magnetism in order to suitable magnetic field to be provided, the armature structure of motor is designed to not have groove pattern simultaneously, the armature winding of motor is arranged in the surface of armature core.
Below with reference to accompanying drawing the utility model embodiment inventive features purpose and effect are further described.
The explanation of accompanying drawing drawing:
Figure one revolving-armature type permanent magnetism slotless electric machines schematic diagram
Figure two revolving-armature type permanent magnetism Smooth dynamo rotor schematic diagrames
Figure three armature core punching schematic diagrames

At first, describe with reference to one to figure four couple of first embodiment of figure.
Figure one expression magnetic pole is an external stator, and armature is the permanent magnetism slotless electric machines of internal rotor.As figure, magnet steel (3) by polar body (2), is fixed on the support (1).Wherein, magnet steel (3) and polar body (2) are formed a magnetic pole of permanent magnetism slotless electric machines.Some magnetic poles and support (1) constitute the stator of motor.
Magnet steel among the figure (3) is the permanent magnetic steel of high-coercive force, high energy product, high remanent magnetism.As rare earth permanent-magnetic material.Polar body (2) is a magnetic conductive material.
The armature core (4) that armature rotor (7) is laminated by silicon steel sheet (5) and arrange thereon armature winding (6) etc. and form.The rotor (7) of figure two expression present embodiments.Figure three expressions constitute the silicon steel sheet (5) of rotor core (4).Silicon steel sheet (5) laminates mutually, and places on the gyroaxis (8), forms armature core (4).Armature core (4) surface should be bright and clean, no convex-concave and burr.On armature core (4), be wound with armature winding (6).And, between armature core (4) and the armature winding (6), armature winding (6) inside separates with insulating material each other.Just in order to simplify drawing, these insulation material layers do not draw in the diagram.
It needs to be noted, each conductor in the armature winding (6) can be according to actual needs solid wire, several threads and around or (with) several threads Split Down strand system forms.The purpose of Split Down strand system is in order to make motor obtain good characteristic.One of preferred plan of Split Down strand system be conductor wire with seven same line footpaths with the position mode Split Down shown in the figure four after evenly strand make.At last, the outermost layer of the rotor (7) of the good armature winding of coiling (6) with the banding insulation material wrap up in fully around.
In order to improve motor performance, in figure one, add polar body (2).Polar body (2) is made by permeability magnetic material.Can be an integral body, also can be to form by the folded system of punching.On the other hand, as the consideration of structural shape aspect, also can be directly installed on that support (1) is gone up to magnet steel (3) and without polar body (2).
Then describe with reference to six couples second embodiment of figure.
In figure six, permanent magnetic steel (13) is installed on the rotor (11) by polar body (12).Armature winding (10) is arranged on the stator core (9).Rotor (11) can be formed by the folded system of the silicon steel sheet shown in schematic diagram three (5), also can be a magnetic conduction integral body.Therefore, in the present embodiment,, armature winding is arranged on the out frame, forms rotary pole formula permanent magnetism slotless electric machines by permanent magnetic steel is installed on the rotor.Similar to first embodiment, permanent magnetic steel (13) is directly installed on rotor (11) and goes up or be fixed on the rotor (11) by polar body (12).Polar body (12) is made by permeability magnetic material.Can be an integral body, also can be to form by the folded system of punching.
Below some details of invention of the present utility model is further described.
The arrangement mode of the armature winding shown in figure one, figure two, the figure six has various ways.
The armature winding (6) of given embodiment and armature winding (10) arrangement mode are two-layer in figure two, figure six schematic diagrames.Promptly the active conductor of the armature winding that will arrange evenly is divided into two equal portions, respectively they be arranged in armature core on the layer that rolls off the production line.
The another kind of form that figure five draws and arranges at the revolving-armature type permanent magnetism slotless electric machines armature core surface armature winding of first embodiment.In figure five, armature winding (15) is divided into four layers of arrangement.Promptly the active conductor of armature winding (15) evenly is divided into quarter, respectively they is arranged on 4 wiring layers of armature core.
