Specific embodiment
The specific implementation of the utility model is described further below in conjunction with attached drawing and example, but the reality of the utility model
It is without being limited thereto to apply protection, is that those skilled in the art can refer to if place is not described in detail especially it is noted that having below
The prior art understand or realize.
A kind of brushless slotless of Novel splicing formula of the present embodiment without rectification adverser permanent magnet DC motor, including external stator,
Inner stator and rotor all parts are connected as shown in Fig. 2, Fig. 4, Fig. 5.The external stator has fixed card slot 3002 and inner stator
The fixed bayonet 4005 of inner stator and external stator be connected；The inner stator has the fixed bayonet 4005 of inner stator and external stator, and outer
Stator card slot 3002 is connected；The inner stator uses partitioned organization, has the fixation bayonet 4001 between default sub-piecemeal, makes default
It is fixed to each other between sub-piecemeal；The inner stator uses slotless configuration, is wound on winding 5002 directly on inner stator yoke 4002,
And it is fixed on inner stator yoke 4002 by consolidating agent；The inner stator has winding 5002 to be wound on inner stator yoke, makes winding
On one side in interior stator inner surface, on one side in interior stator outer surface；The inner stator distinguishes coiling one in each default sub-piecemeal
Winding is covered, makes each default sub-piecemeal can be with separate machined；The rotor makes not there are two the radiation ring 1001 of opposed polarity
It is opposite with the radiation corresponding air gap portion magnetic direction of ring 1001；The rotor has annulus copper sheet between different radiation rings
2001, barrier magnetic field is circulated in the axial direction of air gap；The inner stator has line outlet groove 5003.
The design of the present embodiment is exactly the magnetic field that abundant application radiation ring 1001 generates monopole, and wire cutting generates certain matter
The direct current of amount, operates in Generator Status.Or it is passed through armature supply, make conductor in the magnetic field that radiation ring generates by power
Effect operates in motoring condition so that drive rotor rotates.In design, rotor there are two opposed polarity radiation ring, generation
Magnetic field, a part such as Fig. 5 of each pole cutting stator conductor in rotor high speed rotation；Simultaneously by coil 5002 in difference
Line outlet groove 5003 among radiation ring makes the conductor of the current direction inner stator outer surface slot, in addition the magnetic conduction of inner stator 4002,
The magnetic field intercepts for rotating the coil side for being in inner stator outer surface not are generated without electromotive force.Thus make each coil
Total electromotive force direction is consistent.By deriving it can be concluded that the electromotive force generated isWherein B is magnetic field strength, and v is magnetic field rotating speed, and l is one side length of winding
Degree, N are windings in series the number of turns.It thus can be the electromotive force that different magnetic field polarity on two stators generates by producing in series and parallel
Raw different voltage, it is consistent in the electromotive force direction of coil, make motor operation in Generator Status.When two stators armature around
Group is passed through different direct currents, and the current direction as Fig. 5 generates two sets of armature winding in interior stator interior is opposite.Due to two
Laundry makes place at the coil side of inner stator surfaces externally and internally in the magnetic conduction of the radiation ring position and inner stator 4002 of opposed polarity
In different magnetic field, the power of generation is also different, and the power that wherein inner surface is subject to is greater than outer surface, by deriving power suffered by motor
HaveWherein B is magnetic field strength, and I is every conductor current size, and l is one edge lengths of winding, and N is windings in series
The number of turns.Two stator current differences make rotor by the power in the same direction simultaneously, and then operate in electric motor state.
Each stator is made of four default sub-piecemeals simultaneously.It is default that armature winding 5002 is wrapped in each default sub-piecemeal
On sub- yoke 4002, such as Fig. 5.Then armature winding 5002 is fixed on inner stator yoke 4002 with consolidating agent.Its effect is to make line
Circle during installation can be on one side in interior stator inner surface, on one side in interior stator outer surface, such as Fig. 5, so that rotating excitation field be made only to cut
Secant circle inner stator inner edge, the not side outside sectioned coil inner stator.It can mutually be supported to avoid the electromotive force generated in coil in this way
Disappear, direct current can not be generated when to operating in Generator Status, when operating in electric motor state, can not generate torque.
Coil is during installation on one side in interior stator inner surface, on one side in interior stator outer surface.Because the magnetic permeability of copper is close
Air, so equal in a kind of air-gap field intensity distribution of the brushless slotless of Novel splicing formula without rectification adverser permanent magnet DC motor
It is even.There will be no fluctuations for the direct current in this way generating motor and torque.The main flux that winding generates simultaneously only passes through inner stator
Forming circuit, without the rotor for having permanent magnet, such motor can eliminate the demagnetization effects of armature-reaction, while just not have to
Compensative winding and commutation winding are installed, to reduce the complexity and cost of direct current generator.
The radiation ring 1001 of two opposed polarities of rotor equipment makes the electromotive force of inner stator yoke when cutting inner stator medial surface
It cancels out each other, so that electromotive force will not be generated externally, threatens the staff for using motor.Simultaneously different radiation rings 1001 it
Between there are also annulus copper sheet 2001 with reduce it is different radiation rings 1001 magnetic fields be directly closed between air gap, thus reduce motor leakage
Magnetic.
