Description
Technical field
The present invention relates to a kind of linear electric motors, particularly a kind of automobile-used class tubulose permanent-magnetism linear motor that is applicable to electric automobile.
Background technology
Be that power battery charging be a kind of automobile-used distance increasing unit technology of efficient, high power density in conjunction with free piston internal combustion engine as the electric automobile distance increasing unit with linear electric motors.At present the tubular linear motor overall structure of using axisymmetricly, radial load is cancelled out each other, and does not have the transverse edge effect, the structure of revolving body formula is beneficial to and carries out integrated with the free piston internal combustion engine prime movers simultaneously.But traditional following shortcoming of tubular linear motor ubiquity:
(1) stator punching complex process, the winding difficult arrangement.Be subjected to the restriction of tubular linear motor magnetic circuit, stator need adopt the mode of circumferential arc lamination or piece, makes the stator punching processed complexization; Simultaneously the structure of tubulose comprises the layout of winding on stator to roll off the production line and the outlet difficulty that becomes.These make the difficulty of processing of tubular linear motor stator bigger;
(2) the annular permanent-magnet body specification of finished product is less, and cost is higher.The tubular linear electric mover adopts the annular permanent-magnet body, and finished product annular permanent-magnet body specification on the market is less at present, and this has limited the scale of outer stator winding; The more block permanent magnet cost of annular permanent-magnet body is also higher simultaneously;
(3) radiating condition is relatively poor.The internal environment of sealing makes the radiating condition of tubular linear motor poor, and this is to the operation of tubular linear motor, and especially the operation under high-frequency has bigger negative effect.
Advantage efficient as electric automobile distance increasing unit generator, high power density that the deficiency of conventional tube linear electric motors will be offset undoubtedly becomes its bottleneck of further being used at electric automobile of restriction.
Summary of the invention
Technical problem to be solved by this invention be to provide that a kind of manufacturing process is simple, production cost is low, excellent in heat dissipation effect and the high automobile-used class tubulose permanent-magnetism linear motor of power density.
In order to solve above technical problem, the invention provides a kind of automobile-used class tubulose permanent-magnetism linear motor, the mover iron core of described motor is positive six prismatics, inlay flat permanent magnet on its six side surfaces, one connecting axle passes the mover iron core, affixed with the mover iron core, the two ends of connecting axle link to each other with bracing or strutting arrangement or prime mover; The stator core of described motor is divided into six, adopts the structure of circumferential lamination, is arranged in the outside of mover iron core and permanent magnet, and six side surfaces with the mover iron core are relative respectively; The outside of described stator core is casing, and casing and stator core are affixed.
Described stator core adopts concentrates the winding mode to arrange three-phase coil.
The present invention is when starting, feed three-phase alternating current to coil, the armature field of setting up and the magnetic field interaction of permanent magnet, producing tangential electromagnetic force drags the mover iron core and does straight reciprocating motion at motor internal, the three-phase current size that feeds coil is controlled with phase sequence, obtained the suitable dynamicthrust that rises, and realize the accurate commutation of electromagnetic force, thereby drive prime mover reciprocating motion by connecting axle, move as linear motor this moment; Start the successfully magnetic field intercepts coil of back permanent magnet generation, produce induced electromotive force and induced current at coil, the reciprocating mechanical energy of prime mover is converted to electric energy output, the present invention's this moment moves as linear electric generator.Can realize the electronic switching with generating state of the present invention by the external control unit, thereby realize the integrated of starting-generating.
Compare with existing tubular linear motor, the present invention all has clear superiority on processing technology, production cost, heat radiation, power density:
(1) the present invention replaces conventional tube linear electric motors cylinder stator core with the circumferential form that distributes of six tabular stator cores, avoided the mode of the circumferential arc lamination of stator core or piece, the also layout of very convenient winding of flat stator core is simultaneously simplified greatly thereby stator core stamping sheet processing and winding are rolled off the production line, go out Wiring technology;
(2) the present invention replaces conventional tube linear electric motors cylinder mover iron core with positive six prismatic mover iron cores, thereby the annular permanent-magnet body can be replaced with the tabular permanent magnet, and is applied widely, is conducive to cost simultaneously and reduces;
(3) compare the sealing of conventional tube linear electric motors cylindrical structure, version of the present invention all is in the relative open environment coil, stator core and mover iron core, has effectively improved the problem of conventional tube linear electric motors poor heat radiation;
(4) can be drawn by the conventional tube permanent-magnetism linear motor of Fig. 4 and Fig. 5 same diameter and power and the voltage comparison diagram of class tubulose permanent-magnetism linear motor of the present invention, the present invention is similar to the conventional tube linear electric motors on performance, but the present invention is lighter than conventional tube linear electric motors quality, and therefore tool has great advantage on power density.
