Abstract
The invention provides a stator with a magnetic shielding function for a special motor drop slot opening of an electro-tricycle, relating to a motor. A pure iron or silicon steel magnetoconductive material is used for making a cuboid slot wedge, and a heat-shrinkable magnetic shielding layer is attached to the periphery of the slot wedge. The pure iron or silicon steel slot wedge overcomes the defect that the symmetrical plane of the rotor permanent-magnet magnetic shoes always overlaps the symmetrical plane of the stator tooth part, and lowers the rotary resistance of the stator, so that the electro-tricycle is more convenient to push in case of a power cut; and meanwhile, the invention enables the jitter of the motor operating at low speed to disappear, and lowers the noise of the motor in operation. In order to avoid increasing the magnetic internal loss between adjacent slots due to the connection between the pure iron and the silicon steel strip at the stator tooth part in the operation process of the motor, a heat-shrinkable tube is utilized to tightly hold the slot wedge, or rubber is processed and sulfurized to tightly hold the slot wedge, thereby avoiding the direct connection between the stator tooth part and the pure iron and silicon steel strip. The slot opening width is properly increased from 1.5mm to 1.8-2.5mm to lower the line insertion difficulty, thereby enhancing the production efficiency and economic efficiency.
Description
Technical field
The present invention relates to a kind of motor, be specifically related to a kind of electro-tricycle motor special stator that notch has separated magnetic function that rolls off the production line.
Background technology
The double rear wheel differential drive motors that uses on the electro-tricycle, its rotor assembly is embedded in the rotor that made by silicon steel sheet and that have dovetail groove by eight Nd-Fe-B permanent magnetic property magnetic shoes, and there is armature spindle at the silicon steel sheet center.The winding coil that the stator of motor is made by copper cash embeds in the line embedding groove of being made by silicon steel; According to technological requirement, winding coil must embed from the rule notch, and then the shutoff of rule notch is got up.At present on the market on the electro-tricycle motor stator line embedding groove mouth adopt insulation board or bamboo let shutoff.After the motor assembling; Gap between stator silicon steel sheet endoporus and the rotor permanent magnetism magnetic shoe external cylindrical surface is very little; Because the magnetic field intensity of rotor permanent magnetism magnetic shoe is high, the permanent magnetism magnetic shoe has very large difference to stator teeth attraction and magnet steel to the attraction of stator slot oral area.The difference of this attraction must cause motor when static state, and the plane of symmetry of permanent magnetism magnetic shoe is overlapping with the plane of symmetry of stator teeth all the time, and when motor cut off the power supply, this overlapping stator that makes rotated the generation resistance.Here it is we when the electro-tricycle battery does not have electricity, feel to have the reason of very big resistance with the hand propelled electro-tricycle.This resistance causes the electric motor car tricycle to carry out difficulty through the amplification of reduction gearing.This resistance also can cause motor when low-speed running simultaneously, shows tangible shake.The size of resistance and shake can change along with the size of width of rebate.When width of rebate during greater than 1.5mm, along with the change of width of rebate is big, resistance all can become big rapidly with shake; Can be when motor rotates simultaneously because of notch become big, motor internal produces noise and is also increasing.Line embedding groove is made a slip of the tongue little, and when width was lower than 1.5mm, difficulty strengthened in the time of can causing rule, and production efficiency reduces.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention's provide a kind of electro-tricycle motor special to roll off the production line stator that notch has separated magnetic function utilizes two kinds of permeability magnetic materials of pure iron or silicon steel to make groove and carves, and the peripheral bonding pyrocondensation that groove is carved is at a distance from magnetosphere.Make by pure iron or silicon steel material, reduce the overlapping stator that causes and rotate the generation resistance.Decrease in the magnetic when not allowing stator teeth to increase motor rotation between adjacent slot because of pure iron and silicon steel bar link to each other; With heat-shrink tube pure iron and silicon steel bar are entangled firm at present; Or secure pure iron and silicon steel bar through processing sulfuration with rubber; When this groove was carved the shutoff notch, the tooth portion of stator can directly not link to each other with pure iron and silicon steel bar.Simultaneously, suitably increase width of rebate, be increased to 1.8mm to 2.5mm by present 1.5mm.
The present invention realizes through following technical scheme: a kind of electro-tricycle motor special stator that notch has separated magnetic function that rolls off the production line, motor stator is made up of stator teeth and winding wire bag two parts.Described stator teeth is fixed in the electric machine casing after being superposeed by the multi-layer stator silicon steel sheet; The stator silicon steel sheet along the circumferential direction is uniformly distributed with makes 12 stator line embedding grooves; The inwall of stator line embedding groove is made the rule notch, and the winding wire bag embeds in the stator line embedding groove through the rule notch.Between the inboard and rule notch of winding wire bag with the shutoff of notch packaging system.It is characterized in that: described notch packaging system is carved with pyrocondensation by groove and is formed at a distance from magnetosphere two parts, and described groove is carved and is cuboid, and described pyrocondensation is bonded in the periphery that groove is carved at a distance from magnetosphere.Groove is carved by the pure iron material, also can be made by silicon steel material.
Good effect of the present invention is:
1, making groove with pure iron or two kinds of permeability magnetic materials of silicon steel carves; Has magnetic conductivity; The rotor magnetic shoe is to stator teeth attraction and close to the attraction of stator slot oral area, avoids motor when static state, to cause overlapping with the plane of symmetry of the stator teeth all the time phenomenon of the plane of symmetry of permanent magnetism magnetic shoe, when motor cuts off the power supply; The hand propelled electro-tricycle can not feel to have very big resistance yet.Shake during the motor low-speed running disappears, and reduces the operating noise of motor.
2, the rated current of motor under identical rule data reduces, and the rated efficiency of motor can promote more than 2%, makes electro-tricycle under equal charge condition, more electrical energy saving, and it is farther to go.
3, suitably increase width of rebate, reduce the rule difficulty, production efficiency is high, improves business efficiency.
4, rational in infrastructure, cost of manufacture is low, is convenient to promote the use of.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain.
