Description
Technical field
The present invention relates to a kind of motor of special construction, specifically a kind of stator corresponding integrated electric machine.
Background technology
Common electric machine generally is made up of stator and rotor, and stator includes stator core, stator winding and support, and stator winding is made up of many coil parts that insulated conductor turns in stator core, and stator core and support join.Each coil generally is by the some circles of sub-thread insulated conductor coiling, forms a whole, and is called element.Sometimes in order to satisfy the requirement of processing technology, also use stranded conductor and, link together with multiply and around all tops of lead then around fabrication techniques, all ends also all link together, and finally reach effect and the effect identical with the single cord coiling.The very ripe also relative fixed change of the making pattern of this motor stator, but the weak point that exists is exactly if the insulation of the somewhere of element is broken, just might burn the accident of stator winding; And if rupture in the element somewhere, can influence the stator winding of a whole phase, cause the imbalance or the phase-deficient operation of motor operation, bring serious safety problem thus.
Summary of the invention
Purpose of the present invention just provides a kind of stator corresponding integrated electric machine of brand-new stator winding connecting mode, to overcome the deficiency that exists in the existing motor stator winding mode of connection, improves motor reliability of operation and fail safe.
The present invention is achieved in that the stator corresponding integrated electric machine, form by stator and rotor, stator includes stator core, stator winding and support, and stator winding is made up of the coil part that insulated conductor turns in stator core, and stator core and support join.Each element in the stator winding is made of the sub-element with independent terminals more than at least 2, and the sub-element number in each element equates that all sub-elements in each element are positioned at identical stator slot.Get the sub-element set of in each element one and form a sub-element group, then sub-element group number is just identical with sub-element number in the element.Sub-element in all sub-element groups all interconnects according to the connected mode of element, and respectively draws one group of independently binding post.
The present invention can adopt multi-thread and carry out the coiling of each element in the motor stator winding around technology.Yet, in same element, the end of each bar lead will be no longer directly and connect, but independent tap respectively, thereby in an element, just formed a plurality of discrete " sub-elements " (be made as N, and N 〉=2).Each sub-element all is parts multi-thread and in the element that is produced, and the sub-element in each element takies identical stator slot, promptly in the physical space of motor stator and put.If this moment, all conductor cross-sections were also identical, then each sub-element in the identity element just has identical physics and electrical structure performance naturally, but separate on electrical structure.
Each sub-element in element only is connected with corresponding sub-element in other elements, promptly has only the sub-element of forming same sub-element group to interconnect, its connect correspondence position in rule and the common electric machine each element to be connected rule identical.So just be equivalent to the complete stator winding of the cover of one in the common electric machine is decomposed into geographically overlapping fully N cover stator winding, also can be described as the stator unit of N coordination in support.Like this, each stator unit all has identical, the complete logic function of stator with corresponding common electric machine, becomes N " logic stator ".The shared same rotor of this N stator unit, therefore, each logic stator all forms virtual " a logic motor " with rotor.Each logic motor all has one group of independently corresponding and corresponding with common electric machine binding post.N independently logic motor has constituted " integrate motor " on the physical significance.Core of the present invention just is being this.
Under integrate motor pattern of the present invention, control to each heavy-duty motor can be converted into N the parallel control of the logic motor of smaller power relatively, and then makes that the bigger high-power control transformation of difficulty is the less relatively small-power of difficulty, multiple unit control.Like this, when a certain logic motor or a certain control unit generation local fault or be subjected to external force when damage, only can influence single logic motor, local problem just for integrate motor.As long as can in time go out its switching this moment, integrate motor just can continue stable operation, and can not cause systemic breakdown, and can avoid the situation of motor phase-deficient operation to take place.Can also accomplish " compensatory formula " operation of motor, until maintenance this moment by changing the operational factor of other logic motors.Realized motor stabilizing " operating with failure " thus, and made it have " anti-injuring " ability.This be common electric machine incomparable advantage, can improve motor reliability of operation and fail safe effectively thus.
Description of drawings
Fig. 1 is that each sub-element group is the motor stator winding figure that " Y " shape connects among the present invention.
Fig. 2 is that each sub-element group is the motor stator winding figure that " △ " shape connects among the present invention.
Embodiment
As shown in drawings, stator corresponding integrated electric machine of the present invention, its mechanical structure is identical with the electric machine structure that existing known technology is made, promptly form by stator and rotor, stator includes stator core, stator winding and support, stator winding is made up of the coil part that insulated conductor turns in stator core, and stator core and support join.Each element in the stator winding all is the sub-element formations that had independent terminals by N (N 〉=2), and establishing its label is 1～N.All the sub-element of all same numerals is divided into one group in the element, then total N sub-element group.Each sub-element group connects according to the conventional connected mode between the element in the existing common electric machine stator winding, draws one group (3 pairs) independently binding post then.The binding post of each sub-element group all according to " Y " shape (as shown in Figure 1) or all connect according to the connected mode of " △ " shape (as shown in Figure 2), can be constituted the stator corresponding integrated electric machine that a stator winding becomes " Y " shape or one-tenth " △ " shape to connect respectively.
Therefore the mechanical structure of integrate motor of the present invention and common electric machine is identical, and rolling off the production line by new mode on the support of common electric machine when making gets final product.Sub-element conductor cross-section in each element or line footpath can be identical.Structure because of all sub-elements is identical again, and its operating voltage also equates, so the power of each logic motor also is identical.
The present invention also can have the different sight of conductor cross-section, and promptly sub-element conductor cross-section in each element or line directly have difference.But should guarantee that the conductor cross-section of each sub-element set group or line directly are identical.Like this, the power of each logic motor will be different because of the conductor cross-section or the line difference directly of each sub-element group.
Adopt above-mentioned different structural design, decompose in order to carry out power exactly, make it to form the logic motor that several can satisfy the control unit requirement, to satisfy the different design needs of integrate motor.
In above-mentioned various integrate motors, the binding post of each sub-element set group is connected to a control unit.All control units can be the identical small-power controllers of power parameter, to control the identical logic motor of corresponding power parameter (the sub-element wire diameter is identical); Also can be power parameter and small-power controller inequality, to control corresponding power parameter and logic motor (sub-element wire diameter difference) inequality.Thereby be expected to guaranteeing under standardization, the normalized prerequisite that raising design, the flexibility of making also reduce production costs.
If with the electric parallel connection of binding post of all sub-element set groups, connect a controller that is complementary with whole integrate motor gross power altogether, then this integrate motor just is equal to a common electric machine that utilizes existing known technology to make fully.If N logic motor is connected respectively also and can works in the mode of highly-parallel with a corresponding N control unit, then the final output of integrate motor just is equivalent to a corresponding common electric machine.Because of its total component structure is constant, total copper consumption is constant, and proper as long as control is coordinated, then total peak power output is constant.Also can finely tune by the angle of carrying out between the Different Logic motor-field vector simultaneously, and motor characteristic is improved, promptly output characteristic is more steady, and torque ripple reduces, and the fail safe of motor and control system thereof and reliability but can be protected.
Stator corresponding integrated electric machine of the present invention both may be made in motor, also may be made in generator; Both may be made in AC induction motor, ac synchronous motor, also may be used on the direct current machine field.In a word, when improving motor characteristic, can improve motor reliability of operation and fail safe effectively, thereby be the change of an essence in the field of motor manufacturing.
