Abstract
The utility model discloses a water pump magneto rotor including a rotating shaft, injection mold on the rotating shaft and magneto on the injection mold; the magneto is covered with an injection mold protection coat. Because the magneto of the utility model is completely covered with an injection mold protection coat, the rotor of the magneto boasts large amounts of movement without producing magnetic rag in collision.
Description
Technical field the utility model relates to a kind of water pump rotor, particularly a kind of water pump permanent magnet rotor.
Background technology is well-known, the basic functional principle of permanent magnet water pump is: under the magneticaction of permanent magnet rotor in electromagnetic field in the pump, begin to start and drive blade rotation, when it produces centrifugal action, water is forced out, and to be permanent magnet the add injection moulding of general water pump permanent magnet rotor structure, the power transmission between permanent magnet and the moulding is to come anti-the slip and transmission by the groove of elliptical aperture in the magnet and permanent magnet end face or hole.The structural advantages of this general water pump permanent magnet rotor is simple in structure, injection moulding efficient height, shortcoming is: transfer motion power is little, and injection moulding core frangibility is in addition because permanent magnet is to belong to ceramic-like, so it is frangible, particularly after permanent magnet magnetizes, owing to magneticaction is easy to collide with other magnetic conductor such as iron class workpiece, in case collision, just produce the magnetic bits, will be stuck and there is magnetic to consider to be worth doing water pump.
Summary of the invention is for solving the deficiencies in the prior art parts, and the utility model is special disclose and a kind ofly to improve from structure, big to reach the rotor rotation amount, does not produce the water pump permanent magnet rotor that magnetic is considered to be worth doing simultaneously after the collision.
The technical solution of the utility model is achieved in that one one kinds of water pump permanent magnet rotor, comprises moulding in rotating shaft, the rotating shaft and the permanent magnet on the moulding, and the outer surface of described permanent magnet also is coated with the injection moulding protective layer.
Structural advantages of the present utility model be whole permanent magnet when injection moulding, all be injection molding the layer wrap up comprehensively.Injection molded layers is having the recovery effect after Overheating Treatment, permanent magnet is wrapped in the injection molded layers tightly, even permanent magnet can not produce the magnetic bits in back and other magnetic conductor collision of magnetizing yet like this.Thereby it is big to have reached rotational power, and does not produce the purpose of magnetic bits after the collision.
Description of drawings is further described the utility model below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model
Embodiment
As shown in drawings; a kind of water pump permanent magnet rotor; comprise moulding 2 in rotating shaft 1, the rotating shaft 1 and the permanent magnet 3 on the moulding 2; the outer surface of described permanent magnet 3 also is coated with injection moulding protective layer 4; thereby it is big to reach the permanent magnet rotor amount of spin, does not produce the beneficial effect that magnetic is considered to be worth doing again simultaneously with after other magnetic conductor collision.
