Description
Technical field
The invention belongs to a kind of technical field of motors, more particularly to a kind of two pole hollow-cup motor loop constructions and its coiling
Method.
Background technology
Hollow-cup motor belongs to minitype permanent magnet motor type, and special construction is the enameled wire that coil windings are exoskeletal
The hollow cylindrical structure of self-supporting, the special construction formed motor performance parameter be all kinds of same specification power of motor density most
Greatly, the highest type of efficiency has in such as accurate control of all kinds of high-end applications, aerospace, military science and technology, medical science and technology field
The application advantage that can not be substituted.And current hollow-cup motor coil winding technique is the technical threshold of major micro machine enterprise,
And almost coil configuration structure and process disclosed in existing market are monopolized by foreign countries for a long time, it is new therefore, it is necessary to find
Structure and process are pushed further into technological break-through and the market application of hollow-cup motor.
In the hollow cup coil arrangement being currently known, there are diamond shape coiling and crossing line two major classes, has brush in three-phase
In brushless hollow cup coil structure, each phase continuous coiling is taken to occupy the arrangement of 120 ° of modes of entire coil circumference
Structure, no matter the advantages of this arrangement is crossing line or diamond shape winding mode, each phase coil only has inlet wire and goes out
Existing two the end of a thread, it is that 6 the end of a thread belong to score winding, than integer winding but a disadvantage is that the utilization rate of coil is low to amount to three-phase
Low 15% or so power density；If using integer winding, each phase coil at least wants 2 if using diamond shape butterfly winding mode
Independent coil amounts to minimum 6 independent coils at symmetrical structure, then each phase coil can draw two into the end of a thread and two outlets
Head, entire cylindrical type three-phase coil, which can go out, generates six lead risers, and subsequent technique is needed two independent coils of each phase
Inlet-outlet line carry out line be a phase coil, technique is very cumbersome, can only manually carry out not only poor reliability, production efficiency nor
It is often low.
Invention content
In order to solve one or more drawbacks described above in the prior art, technical problem to be solved by the invention is to provide
Two pole hollow-cup motor loop constructions of one kind and its winding method improve coil utilization rate, improve power of motor density, simplify work
Skill.
To achieve the above object, include being set in outside magnet steel the present invention provides a kind of two pole hollow-cup motor loop constructions
Cylindrical shape solenoid, which is characterized in that the solenoid include three coil groups, any coil group only by one
Coiling coiling and containing only there are one into the end of a thread and a terminal, the solenoid is turned to by the coiling of three coil groups
Exoskeletal hollow cylindrical coil.
Further, the solenoid includes three coil groups, each coil group cross arrangement successively, each line
Circle group includes two absolute coils centrosymmetric each other for being wound on cylindrical surface, and two absolute coils are by same coiling
Coiling is concatenated, the upper shared arc length of end face circle of solenoid of each absolute coil in cylindrical shape is 1/6 circumference
Degree (i.e. corresponding central angle is 60 °)
The winding method of two pole hollow-cup motor coil of this programme is as follows：
(1) entire coil is divided into tri- coil groups of A, B, C, when beginning, the coilings of A coil groups is from a cylindrical end
Any point starts coiling on the circumference of face, and the surface coiling along cylinder is i.e. 180 ° opposite with starting point to another cylindrical end face
Position, then return to starting point along the surface of cylinder at same direction, form the first circle coil；It is opened later close to the first circle coil
Beginning coiling the second circle coil, and so on repeat coiling, always around the width for 1/6 arc length for occupying end face circumference, Zhi Houyin
Go out coiling reversed to 180 ° of positions of the same end face circle of leading point start it is oppositely wound as stated above, always around accounting for
According to the width of 1/6 arc length of end face circumference, the molding of A coil groups coiling at this time；
(2) start coiling B coil groups next to A coil groups according to the method for step (1), after B coil group coilings molding,
Start coiling C coil groups；After C coil group coilings molding, tri- coil groups of A, B, C arc for respectively occupying on the same end face is justified
A length of 1/3 circumferential length, at this time tri- coil groups of A, B, C form an exoskeletal hollow cylindrical coils.
When using this programme, the present invention will be divided into entire coil three coil groups i.e. three-phase, the distribution of each coil group
Two parts are respectively centrosymmetric, and arrangement occupies 1/6th arc length of circumference.When coiling, waveform winding method one is first pressed
A direction several circles of coiling for example clockwise occupy 1/6th of circumference, then lead-out wire rotates to the opposite position of circumference reversely again
The equal the number of turns of coiling occupies 1/6th；Other two groups of coils and so on, turn to a hollow whole coil of cylindrical type.
The present invention at least has the advantages that：The arrangement of coil of the present invention meet it is whole away from whole slot it is distributed around
Group structure, makes power of motor density maximize.On electromagnetic structure have symmetry, it is whole away from integer coiling arrange and only
Six extraction the end of a thread, it is simple in structure to be easy to make, power of motor density maximize and and the end of a thread it is few it is simple for process be conducive to production,
So that more efficient.
