Abstract
The utility model relates to a DC motor rotor core structure, comprising a rotor core body, characterized in that the rotor core body is provided with a hollow structure, the hollow portion is filled with a resin insulation medium body in a method of injection molding. The DC motor rotor core structure is reasonable in structure design, small in metal consumption, and smaller in copper loss and iron loss, and has the characteristics of being high in efficiency, light in weight, small in rotational inertia, high in reliability and low in cost, thereby enhancing electric energy conversion efficiency, improving distribution of magnetic force lines, enhancing magnetic flux density, and increasing comprehensive electrical performance of the motor; and is an upgraded product based on a traditional permanent magnet DC motor, is simple in preparation process, and omits a plurality of preparation steps.
Description
Technical field
The utility model belongs to the rotor DC machine iron core, concrete relates to a kind of improvement that utilizes structure and technology, promotes the rotor core structure of the direct current permanent magnet motor of motor performance.
Background technology
Iron core and coil in the rotor winding of conventional motors, its iron core metal are than great, so quality is heavy, and motor exists bigger copper loss and iron loss when operation, and efficient is difficult to improve significantly.In sum, make conventional motors exist bigger energy consumption, productivity effect is not high.
For reducing the metal consumption of iron core, occurred adopting dielectric to replace the core of iron core in the prior art, with reduction irony consumption, but the binding ability between this dielectric and iron core is poor, can't satisfy the requirement of electronics rotor winding.
The utility model content
The utility model provides a kind of iron core metallic object few, the DC motor rotor core structure that copper loss and iron loss are all less, and it is simple in structure; 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 the upgrading products of traditional permanent magnet DC motor.
The technical scheme that the utility model adopted is following:
A kind of DC motor rotor core structure comprises the rotor core body, it is characterized in that said rotor core body has hollow structure, this hollow space injection moulding potting resin dielectric body.
In the embodiment, the hollow space of said rotor core body is the circular configuration that edge distribution has support slot.
In one embodiment, said rotor core axle center is provided with axostylus axostyle, and the part that axostylus axostyle combines with the rotor core body is for being in strip annular knurl and adding the support slot structure.
In another embodiment, the setting of combining closely of said insulation resin dielectric and said rotor core body.
This DC motor rotor core structure 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 body 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 the rotor core body is in strip annular knurl and adds support slot, the axle that makes and the retain strength >=19.5NM of rotor core body.
The beneficial effect of the utility model is that this DC motor rotor core structure is reasonable in design, and the iron core metallic object 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, reaches 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 utility model is done further elaboration.
