Specific embodiment
As Fig. 1 be shown in a kind of high-speed rail car door driving motor implement structure diagram.By bearing, stator core, armature around
Group, permanent magnet, pulley, door-plate, axis, guide rail composition；The pulley on axis is fixed on to be located among the two sides door-plate of high-speed rail car door；Door
Stator core is respectively fixed with towards the two sides of pulley on the inside of plate；Axis is mounted on door-plate using the bearing at both ends.
As Fig. 2 be shown in a kind of high-speed rail car door driving motor side view.It is solid respectively towards the two sides of pulley on the inside of door-plate
Surely there are 9 pairs of sub- stator cores, every pair of sub- stator core is made of two identical sub- stator cores, adjacent two pairs of sub- stator cores
Along the circumferential direction differ 30 degree；
Every sub- stator core has the armature pole stretched out to axle center, and one side of the armature pole towards pulley is in fan
Shape；The root of armature pole is wound with a centralized armature winding in every sub- stator core；
The pulley is identical with the coiling direction of armature coil in the sub- stator core on one side；It is same to sub- stator iron
The coiling of two armature coils in the heart is contrary.
The fan-shaped outer diameter of pulley fan-shaped pylone is bigger than the outer diameter of armature pole end face sector, the fan-shaped internal diameter of pulley fan-shaped pylone
Internal diameter than armature pole end face sector is small.
As Fig. 3 be shown in a kind of high-speed rail car door driving motor pulley figure.8 fan-shaped pylones are evenly equipped on pulley circumference,
Junction between two through-holes is made of permeability magnetic material；The periphery of pulley has V-groove, can slide on guide rail；It is sliding
The not side of stator core and guide rail contact on wheel.
As Fig. 4 be shown in a kind of high-speed rail car door driving motor permanent magnet figure.By permanent magnet, stator core, axis, guide rail group
At.The junction of the sub- stator core of described every pair accompanies a permanent magnet；The end face of permanent magnet is in rectangle；All permanent magnets
Magnetizing direction is identical.
Its working principle is that: since excitation source (permanent magnet or electrical excitation magnetic pole) of the invention and armature pole are right in the axial direction
Together, therefore when the part of rotor core energy magnetic conduction is aligned with armature pole, the magnetic resistance minimum of the armature pole linkage, armature winding magnetic
Chain is maximum；When the fan-shaped pylone of rotor core is aligned armature pole, the magnetic resistance of the armature pole linkage is maximum, armature winding magnetic linkage most
It is small；When the part of rotor core energy magnetic conduction moves closer to armature pole, the mutual inductance of the phase armature winding and excitation winding is increasing；
The self-induction of the phase armature winding is also increasing.When rotor core energy magnetic conduction is when being partially disengaged armature pole, the phase armature winding with
The mutual inductance of excitation winding is increasing.The self-induction of the phase armature winding is also reducing.Due to pulley fan-shaped pylone number and armature pole
The ingenious combination of number, the armature winding in every sub- stator core have its unique phase.
Since the magnetic linkage of the self-induction of the application armature winding, armature winding linkage is also constantly changing, so if
It is powered to excitation winding and excitation field and movable rotor iron core is provided, then armature winding can generate induced electromotive force.Here it is this
The principle that application motor is run as generator.
When the application motor is as motor running, positive electricity is passed to the phase winding for generating positive induced electromotive force
Stream, then the winding can produce positive torque；Pass to forward current to the phase winding for generating negative induced electromotive force, then it should be around
Group can produce negative torque.Three-phase current is passed to according to phase difference, can be rotated with driving pulley.
