Description
Technical field
The present invention relates to motor, specifically is a kind of high-power disc type drive motors of high power density with axial flux structure.
Background technology
At present, the desk permanent-magnet motor of axial magnetic circuit has multiple way of realization, as: internal rotor shape---rotor of two stators is arranged; External rotor shape---two rotors are arranged, a stator; Single-side structural---stator of a rotor; Polygon structure---have a plurality of rotors and a plurality of stator.But all there is following deficiency in above structure:
(1) with regard to the inner rotor core of two stators, single rotor, permanent magnet need be directly embedded in the rotor disk, thereby rotor disk must be non-magnet_conductible material and have very high mechanical strength, and magnet steel is difficult with fixing.In micro-machine, can adopt the high-intensity resin material directly permanent-magnet steel to be poured into the method for rotor disk, but this method is hour feasible at the rotor radius, and in case change big volume into, powerful motor just is difficult to realize; Document " high density AFIR disc wheel Design of PM Motor " has proposed a kind of fixedly method of magnet steel of stainless steel stent that adopts, and there is the magnet steel location difficulty in this method, complex process, the little deficiency that waits of mechanical strength; In the document " design and research of high power density disc type permasyn motor "; Be employed in the method for two-sided stationary permanent magnet on the rotor yoke iron, utilize the suction of permanent magnet and yoke fixing through the super glue bonding again, adopt this method just must adopt thicker rotor yoke; To prevent the magnetic saturation of yoke; Because the existence of rotor yoke iron has caused the magnetic loss of motor to increase, reduced efficiency of motor simultaneously.
(2) to two rotors are arranged, the outer-rotor structure of a stator, rotor disk must be permeability magnetic materials; Need magnetic circuit be provided for permanent magnet; Because stator component is clipped in the middle of two rotor disks, the film-cooled heat of motor reduces greatly, is unfavorable for being designed to high-power water-cooled machine simultaneously;
The single-side structural of (3) stators, a rotor; The film-cooled heat of stator is unaffected; But owing to have magneticaction all the time between rotor permanent magnet and the stator; Have very big axial magnetic pull in the rotating shaft, increased the load of bearing, especially be unfavorable for being made into motor high-power, big volume;
(4) to many rotors, multiple stators structure, it is very complicated that electric machine structure will become, and the requirement of processing technology is improved greatly, and it is big that the difficulty of Electric Machine Control becomes, and also increased the complexity of the motor type of cooling simultaneously.
Summary of the invention
Technical problem to be solved by this invention is, a kind of deficiency that overcomes existing axial-flux electric machine is provided, and provides a kind of volume high power density little, in light weight, that power density is high, efficient is high high-power disc type drive motors.
The high-power disc type drive motors of high power density of the present invention is the axial flux structure with two stators, single rotor, and it comprises installation stator core and rotatable rotor dish in the enclosure; Said rotor disk comprises rotor pallet and permanent magnet, and the rotor pallet is discoid, is fixed with permanent magnet respectively on two end faces of rotor pallet, and permanent magnet circularizes along the circumferential arrangement of rotor pallet; Respectively there is a stator core rotor disk both sides, are embedded with stator coil in the stator core, and stator core is fixedly connected with the end cap at shell two ends; Permanent magnet on the rotor disk both ends of the surface forms air gap with the inner face of two stator cores respectively.
Said rotor pallet is processed by non-magnetic material; Said permanent magnet is divided into two kinds, and a kind of is the pole orientation vertical pole permanent magnet vertical with the card of rotor pallet, and another kind is the pole orientation parallel magnetic pole permanent magnet parallel with the card of rotor pallet; Said vertical pole permanent magnet is arranged along circumference is staggered with parallel magnetic pole permanent magnet, between promptly per two adjacent vertical straight magnetic pole permanent magnets a parallel magnetic pole permanent magnet is arranged, and a vertical pole permanent magnet is also arranged between per two adjacent parallel magnetic pole permanent magnets; And the pole orientation of per two adjacent vertical pole permanent magnets is opposite, and the pole orientation of per two adjacent parallel magnetic pole permanent magnets is also opposite.
Be respectively arranged with cooling jacket on the end cap at said housing two ends.
Because adopt above technical scheme, the present invention has following advantage:
(1) rotor magnetic steel has adopted two-sided array distribution, has increased the effective area and the air gap magnetic field intensity of magnet, has improved the power density of motor;
(2) the rotor pallet of non-magnet material does not have magnetic loss, has improved efficiency of motor; Because the rotor pallet does not constitute magnetic circuit,, can reduce the axial length of motor to not restriction of thickness;
(3) stator faces is installed cooling jacket, and film-cooled heat is big, has improved power of motor density effectively;
The coil of (4) two stators can carry out the serial or parallel connection combination, and motor can be worked under different rated voltages;
(5) motor volume is little, and is in light weight, and efficient is high, and rotor weight is light, and control performance is good, and can realize high-power.
