It is commercial and police.
Motor is as the automobile-used power unit of electrodynamic balance, and its performance impact has arrived the driveability of electrodynamic balance car and made
Use effect.Motor includes shell, permanent-magnet stator, armature rotor and Hall element, and permanent-magnet stator is fixed on the inwall of shell, electricity
Pivot son to be inserted in shell, Hall element is fixed on the rotor core of armature electronics, armature rotor is in high-speed rotation, production
Heat amount, demagnetizes, and reduces the service life of motor.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of demagnetization rate low rotor
Iron core.
To achieve the above object, the utility model provides following technical scheme：
A kind of motor rotor core, including iron core body and rotor windings, the rotor core include cylindric rotor
Cylinder and several the T-shaped supports being connected on rotor cylinder outer circumference surface；
Each T-shaped support extends to the other end from one end of rotor cylinder along its axis direction；
Several T-shaped supports are evenly distributed on the outer circumference surface of rotor cylinder；
The quantity of the rotor windings is consistent with the quantity of T-shaped support, and rotor windings are wound with each T-shaped support；
One end of the rotor cylinder offers heat emission hole, and the heat emission hole extends to it along the axis direction of rotor cylinder
The other end.
By using above-mentioned technical proposal, the setting of heat emission hole can not only reduce material, reduce cost, most importantly
Radiating effect for improving rotor cylinder.
The utility model is further arranged to：The cross section of the heat emission hole is set to ingot shape.
By using above-mentioned technical proposal, the heat emission hole increasing heat radiation area of ingot-shaped structure.
The utility model is further arranged to：The heat emission hole is provided with several, along the radial distribution of rotor cylinder.
By using above-mentioned technical proposal, make the radiating of rotor cylinder evenly.
The utility model is further arranged to：The outer surface of the rotor cylinder and T-shaped support is sprayed with insulating lacquer layer, institute
The insulating lacquer layer stated on T-shaped support relative rotor winding other end is removed by polishing.
The utility model is further arranged to：The thickness of the insulating lacquer layer is 0.12-0.22mm.
By using above-mentioned technical proposal, the rotor core being made up of rotor cylinder and T-shaped support passes through its distinctive sky
Between structure, in high-speed rotation, be easy to the volatilization of heat；In addition, the heat emission hole opened up on rotor cylinder can be further functioned as
The effect of radiating.Therefore, the utility model has demagnetization rate low, can improve the service life of motor.
Brief description of the drawings
Fig. 1 is the schematic diagram of motor rotor core embodiment.
In figure：1st, iron core body；11st, rotor cylinder；12nd, T-shaped support；2nd, heat emission hole.
Embodiment
The utility model motor rotor core is described further with embodiment referring to the drawings.
According to Fig. 1, a kind of motor rotor core, including iron core body 1 and rotor windings, rotor core includes cylinder
The rotor cylinder 11 of shape and several the T-shaped supports 12 being connected on the outer circumference surface of rotor cylinder 11；Several T-shaped supports 12 are equal
It is even to be distributed on the outer circumference surface of rotor cylinder 11, and extended to from one end of rotor cylinder 11 along its axis direction another
End；The quantity of the rotor windings is consistent with the quantity of T-shaped support 12, and rotor windings are wound with each T-shaped support 12；By turning
The rotor core that sub- cylinder 11 and T-shaped support 12 are constituted, by its distinctive space structure, in high-speed rotation, is easy to heat
Volatilization.Therefore, the utility model has demagnetization rate low, can improve the service life of motor.
One end of rotor cylinder 11 offers the hot hole that cross section is ingot shape, axle of the heat emission hole 2 along rotor cylinder 11
Line direction extends to its other end, and the setting of heat emission hole 2 can further function as the effect of radiating, and heat emission hole 2 is set to
Ingot-shaped structure, increases its cross-sectional area, improves area of dissipation.
The outer surface of rotor cylinder 11 and T-shaped support 12 is sprayed with insulating lacquer layer, and the T-shaped relative rotor winding of support 12 is another
Insulating lacquer layer on end face is removed by polishing.The interference for being provided for reduction signal of insulating lacquer layer.The thickness of insulating lacquer layer
For 0.15mm.
Armature spindle is inserted with the inner ring of rotor cylinder 11, armature spindle is interference fitted with rotor cylinder 11, and armature spindle is by aluminium
Alloy material is made, and the armature spindle that aluminum alloy materials are made is more preferable compared to the armature spindle heat dispersion that more traditional iron material is made.
