A kind of armature rotor iron core of four utmost point direct current permanent magnet motors comprises the rotor core body, it is characterized in that said rotor core body has hollow structure, and this hollow space injection moulding is filled with the insulation resin medium.
In the embodiment, the hollow space of said rotor core is the circular configuration that edge distribution has support slot.
In one execution mode, said rotor core body is that the folded riveting of the automatic stamping-out of stamping machine forms.
In another execution mode, said insulation resin medium is the PVC dielectric, and this PVC dielectric forms for the hollow space that directly injects rotor core through injection mold.
In the execution mode, said rotor core is pressed into axostylus axostyle through worker's clamp device by hydraulic press again, and the part that axostylus axostyle combines with rotor core is for being in strip annular knurl and adding the support slot structure.
The present invention also provides a kind of preparation technology of armature rotor iron core of four utmost point direct current permanent magnet motors, it is characterized in that said preparation technology comprises:
Adopt the folded riveting of the automatic stamping-out of stamping machine to prepare the rotor core body; Utilize injection mold directly to inject the PVC dielectric at the hollow space of rotor core body; This hollow space is the circular configuration that edge distribution has support slot, and this PVC dielectric combines with rotor core body one.
In the embodiment, said preparation technology further comprises:
Be pressed into axostylus axostyle in the axle center of rotor core by hydraulic press through worker's clamp device, the part that axostylus axostyle combines with rotor core is for being in strip annular knurl and adding the support slot structure.
The armature rotor iron core of this four utmost points direct current permanent magnet motor is designed to the circle with support slot with the core of rotor core body, reduces metallic object to greatest extent, increases the resistance of metallic object, reduces iron loss.The metallic object of rotor core is formed by the folded riveting of the automatic stamping-out of stamping machine, realizes that metallic object centre-of gravity shift value is little, and structure is tight, and aequum is little.Insulating medium layer directly injects the PVC dielectric by injection mould, concentrates many cover technologies.The armature rotor iron core can be pressed into axostylus axostyle by hydraulic press through worker's clamp device, and because of the craft precision maintenance of injection mold, the combination form and position tolerance deviation of axostylus axostyle and rotor is little, and the spin balancing amount deviation of rotor is little; The partial design that axostylus axostyle combines with rotor core is in strip annular knurl and adds support slot, the axle that makes and the retain strength >=19.5NM of rotor core.
Beneficial effect of the present invention is; The iron core metallic object of the armature rotor iron core of this four utmost points direct current permanent magnet motor is few; Copper loss and iron loss are all less, its have the efficient height, in light weight, moment of inertia is little, reliability is high; The characteristics that cost is low; Can promote electric energy conversion efficiency, improve the magnetic line of force and distribute, it is close to strengthen magnetic; Reaching the piece electrical performance that promotes motor, is traditional permanent magnet DC motor upgrading products.Its preparation technology is simple, has omitted the multiple tracks preparation section.
Below in conjunction with accompanying drawing and embodiment the present invention is done further elaboration.
