Description
Technical field
The utility model relates to machine field, is specifically related to a kind of insulation without the high-power external rotor high-speed electric expreess locomotive of magnetic teeth groove stator core.
Background technology
In traditional magneto body, on armature core, there is teeth groove, easily occur cogging torque.Due to the existence of stator teeth groove, when p-m rotor magnetic pole is relative with stator teeth groove during at diverse location, there is variation in the magnetic conductance of main magnetic circuit.Even motor winding no power, due to the effect of cogging torque, rotor has and is parked in the trend on several settling positions on circumference.In the time that motor rotates, cogging torque shows as a kind of additional pulsating torque, although it can not make the torque of motor average effective increase or reduce, it seems more obvious while causing velocity perturbation, motor oscillating and noise, particularly light load and low speed.In the time of variable speed drives, if approaching system frequency, cogging torque frequency may produce resonance and intense noise.In the time starting, because the existence of cogging torque need to increase initial starting torque, this is just more responsive without transducer control mode for some in addition; For single-phase permanent brushless motor, excessive cogging torque even makes motor normally not start.In order to reduce the cogging torque of magneto, way adopts slotless structure exactly the most thoroughly, and non-gullet motor can be eliminated cogging torque and slot ripples, rotor is rotated and tend to be steady.
For example, and traditional non-gullet motor is that winding is attached to smooth iron core surface or stator adopts non iron-core structure (: hollow-cup motor etc.) mostly.The former relatively bothers in setting-in, the insulation process of coil, and the bulk strength of stator is bad; The latter, because stator adopts insulation framework structure more, make its heat-conducting effect poor, and motor overall structure is larger, has limited its development to high-power direction.
Utility model content
Based on above weak point, the utility model provides a kind of and insulate without the external rotor Large-power High-Speed motor of magnetic teeth groove stator core, and the utility model overcomes tradition the cogging torque of teeth groove motor, and bulk strength is low; The setting-in of existing slotless magneto coil, insulation trouble, stator heat-conducting effect is poor, cannot be designed to the deficiency of the aspect such as high-power.
The purpose of this utility model is achieved through the following technical solutions:
A kind of insulation without the high-power external rotor high-speed electric expreess locomotive of magnetic teeth groove stator core, comprise motor stator and motor outer rotor, it between motor stator and motor outer rotor, is air gap, motor stator comprises that insulation is without the stator core of magnetic teeth groove, stator coil, stator core installing rack, stator core binding ring and stator core fitting key, insulation is installed on stator core installing rack without the stator core of magnetic teeth groove, insulation positions with stator core fitting key without magnetic teeth groove stator core two ends, insulation is fastening with stator core binding ring without magnetic teeth groove stator core one end, stator coil setting-in to electrical machine insulation without in magnetic stator slot, described motor outer rotor comprises motor outer rotor magnet steel and motor outer rotor iron core.
The utility model also has some technical characterictics like this:
Described insulation comprises stator magnetic guiding loop without the stator core of magnetic teeth groove, stator insulation is without magnetic tooth bar, the first insulation is without magnetic tooth bar positioning disk, second insulate without magnetic tooth bar positioning disk and insulate without magnetic tooth bar platen, stator insulation without magnetic rack buckle on stator magnetic guiding loop, stator insulation first uses first without magnetic tooth bar two ends, the second insulation is located without magnetic tooth bar positioning disk, and then compress without magnetic tooth bar platen with insulating, stator insulation is uniformly distributed on stator magnetic guiding loop without magnetic tooth bar, adjacent two stator insulations are without forming electrical machine insulation in the middle of magnetic tooth bar without magnetic stator slot, for setting-in stator coil.
Principle of the present utility model is: the utility model adopt stator insulation without magnetic rack buckle on stator magnetic guiding loop, locate without magnetic tooth bar positioning disk with insulation at two ends, finally compress and form insulation without the stator core of magnetic teeth groove without magnetic tooth bar platen with insulation again, insulation is uniformly distributed on stator magnetic guiding loop without magnetic tooth bar, between adjacent two tooth bars, form stator slot, coil is inlaid in stator slot.Because the tooth bar that forms stator slot is for insulation non-magnet_conductible material, be just equivalent to not have teeth groove, so can eliminate cogging torque and slot ripples in the time of motor rotation and speed change, rotor is rotated and tend to be steady.Coil of stator of motor is close to stator magnetic guiding loop by insulation simultaneously, can effectively reduce the heat of coil of stator of motor.
The utlity model has following useful effect:
The utility model advantage is compared with prior art: the utility model utilizes insulating material and permeability magnetic material to form insulation without the stator core of magnetic teeth groove, has following characteristics compared with existing slotless permanent magnet high-speed motor:
(1) more existing slotless permanent magnet high-speed motor, the utlity model has the advantage that setting-in, insulation processing are simple, bulk strength is high of coil: coil setting-in has teeth groove motor identical with common, because the material that forms stator slot is for insulation non-magnet_conductible material, so only need to do the insulation between winding and magnetic guiding loop.
(2) more existing stator non iron-core motor (for example: hollow-cup motor), the utlity model has the advantage that thermal conductivity is good: because winding is near stator magnetic guiding loop, so heat is easily derived.The skeleton entirety that winding is installed than its stator of the aircored motor of stator is insulating polymer material, and heat-conducting effect will obviously be improved.
(3) more existing stator non iron-core motor (for example: hollow-cup motor), the utility model more easily designs and produces into high-power.Because stator non iron-core motor generally has two rotors, be used to form magnetic loop, so physical dimension is bigger than normal.And the utility model structure and common electric machine structural similarity do not limit in structure aspects, be more suitable for making heavy-duty motor.
