Abstract
The utility model provides a molding half-element winding structure for a high-specific-power motor. According to the technical scheme provided by the utility model, a winding element is a molding half-element; the molding half-element is a half-element which is molded by using a flat copper enameled wire (or a naked copper wire) and is provided with molding elbows at two ends; a plurality of rectangular open grooves are uniformly distributed in an inner hole of a stator along the circumference; molding half-elements are arranged in the rectangular open grooves in two layers; a plurality of molding half-elements are radially embedded into the lower layers of the rectangular open grooves; a plurality of molding half-elements are radially embedded into the upper layers of the rectangular open grooves symmetrically to the lower layers; contacted molding elbows on the molding half-elements are welded together, so that a wave-wound winding is constructed; and slot wedges are inserted into the two ends of each rectangular open groove along a length direction. According to the molding half-element winding structure, high groove filling rate can be ensured, complex tool clamps are omitted, and the reliability of a manufactured motor is ensured; and the molding half-element winding structure is particularly suitable for small-scale and multi-variety production.
Description
Technical field
The utility model relates to the used for electric vehicle electric drive motor, in particular for the moulding half component type winding construction of high-specific-power motor.
Background technology
In the existing used for electric vehicle electric drive motor; No matter be asynchronous machine or permanent magnet synchronous machine or brshless DC motor; Its stator generally adopts the multiply enamel insulated round copper wire and makes around mode, because the objective reality in the gap between the enamel-cover circle line, and the influence in the dead band that the interference between each groove winding forms after the winding employing distribution coiling; Groove wire embedding degree can only maintain a reduced levels, and there is following shortcoming in this method in the manufacturing practice of electric drive motor:
Low copper factor present situation causes electric drive motor or must design with bigger volume and hold enough leads to reach specified power (or torque) requirement; Can increase motor weight like this, reduce motor specific power (power divided by volume or power divided by weight).Keep constancy of volume, make machine operation under higher working temperature, the perhaps magnet steel of the insulating material of motor, efficient, bearing is selected for use and has all been received restriction.
In order to reach high-specific-power, high efficiency and the temperature rise of control motor and the purpose of volume; The raising groove wire embedding degree is one and effectively improves direction; In that this side up, abroad the someone has adopted with profile member and ripple around mode embedding system motor windings, after embedding system is accomplished; Turn one's head in the end, then welding.Though adopt this method can significantly improve groove wire embedding degree, the shaping mould more complicated of electrical machine element, needs are made the complicated frock of turning one's head.Motor stator end easy damage winding when turning one's head causes stator winding end to the stator core short circuit in addition, and the power of drive motors is big more, and the problems referred to above can be outstanding more.If in addition the every groove conductor of motor number reach 4 or more than, then not only need 2 cover size differences but shape is similarly turned one's head frock, and stator winding end wants secondary to turn one's head, element Forming Quality and insulation property more cannot say for sure to demonstrate,prove.And electric drive motor often kind is numerous, in batches less, according to said method make the remarkable increase that can cause manufacturing cycle and cost.
Summary of the invention
The utility model proposes to be used for the moulding half component type winding construction of high-specific-power motor, can guarantee higher copper factor, avoid complicated frock clamp again, guarantees the reliability of the motor of manufacturing, is fit to many kinds, the small lot batch manufacture of electric drive motor.
The technical scheme of the utility model is: the moulding half component type winding construction that is used for the high-specific-power motor; It is characterized in that: the element of winding is a moulding half dollar spare; Structure is: confirm that according to the length of stator the length of flat copper enamelled wire, the both ends of flat copper enamelled wire are the shaping elbow of symmetry; The endoporus of stator is uniformly distributed along the circumference and is provided with a plurality of rectangular aperture grooves; The arrangement form of moulding half dollar spare in the rectangular aperture groove is two layers; A plurality of moulding half dollar spares are from radially being embedded in the lower floor of a plurality of rectangular aperture grooves, a plurality of moulding half dollar spares with the mode of placing with the lower floor symmetry from radially being embedded in the upper strata of a plurality of rectangular aperture grooves; The shaping elbow of the moulding half dollar spare on upper strata contacts under the moulding half dollar spare of each rectangular aperture groove lower floor and the rectangular aperture groove, and the shaping elbow of contact welds together, and constitutes the winding of ripple around mode; Each rectangular aperture groove two ends along its length is inserted with slot wedge.
Beneficial effect: the utility model is owing to adopt moulding half dollar spare;, accomplished half dollar spare the end moulding when making; Half dollar spare is directly put into the rectangular aperture groove of stator during stator built-in line, fixes through slot wedge, has saved the end operation of turning one's head; Simultaneously also guaranteed copper factor, embedding speed is fast, the manufacturing cycle short; In addition in the manufacture process frock clamp simple in structure, quantity is few.Be particularly suitable for small lot, many variety production.

Embodiment
The moulding that is used for the high-specific-power motor half component type winding construction as shown in Figure 1; The endoporus of stator 1 is uniformly distributed along the circumference and is provided with a plurality of rectangular aperture grooves 2; The arrangement form of moulding half dollar spare 4 in the rectangular aperture groove is two layers; A plurality of moulding half dollar spares 4 are from radially being embedded in the lower floor of a plurality of rectangular aperture grooves, a plurality of moulding half dollar spares 4 with the mode of placing with the lower floor symmetry from radially being embedded in the upper strata of a plurality of rectangular aperture grooves; Each rectangular aperture groove two ends along its length is inserted with slot wedge 3, is used for fixing moulding half dollar spare.
As shown in Figure 2 is open slot enlarged drawing on the stator, can find out clearly that the endoporus of stator 1 is provided with rectangular aperture groove 2.
As shown in Figure 3, the structure of moulding half dollar spare 4 is: confirm that according to the length of stator the length of flat copper enamelled wire, the both ends of flat copper enamelled wire are the shaping elbow 5 of symmetry.
In conjunction with shown in Figure 4, the shaping elbow 5 of the moulding half dollar spare 4 on upper strata contacts under the moulding half dollar spare 4 of each rectangular aperture groove lower floor and the rectangular aperture groove, and the shaping elbow 5 of contact welds together, and constitutes the winding of ripple around mode.
Described flat copper enamelled wire also can substitute with bare copper wire, but must carry out insulation.
