Abstract
The invention relates to an external rotor motor capable of raising protection grade which comprises an external rotor, a stator and a fixed axle which are arranged in the external rotor. The stator is fastened on the fixed axle. Two ends of the fixed axle are installed with bearings. The external rotor rotates through the bearing on the fixed axle. The external rotor motor in characterized in that: the external rotor is cast as one body with a cast aluminum rotor and a cast aluminum housing; the two ends of the external rotor are provided with end caps with fixed screws; the two ends of the fixed axle extend from the end caps respectively; a frame type rotation oil sealing device is arranged between the fixed axle and the end caps; the stator is embed with coil which is connected with leading-out wire; the leading-out wire goes through a through wires hole in the center of the fixed axle; sealing filler is filled between an outer wall of the leading-out wire and the through wires hole of the fixed axle; and the gap between the external rotor and the end cap end cap are sealed with a sealing member. The external rotor motor in the invention has the advantages of simple structure, beautiful profile and zero additional apparatus, and protection grade of the external rotor motor is raised to IP66 effectively.
Description
Technical field
The present invention relates to a kind of outer rotor motor of high-protection level, especially a kind of outer rotor motor that can improve degree of protection to IP66 belongs to field of motor manufacturing.
Background technology
Along with outer rotor motor being extensive use of of blower fan field, more and more require outer rotor motor can adapt to the operational environment of the rainy water of many dusts, promptly require the outer rotor motor of high-protection level.And because the inherent structure of outer rotor motor; so its degree of protection is general or be IP44 or IP54; be by in Fan Equipment, adding other safeguard procedures; as increase rainhat, thereby allowing outer rotor motor protect, increase dust filtration device etc. improve degree of protection in Fan Equipment.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of outer rotor motor that can improve degree of protection is provided, can in the adverse circumstances of the rainy water of many dusts, use.
According to technical scheme provided by the invention, the described outer rotor motor that can improve degree of protection, comprise external rotor, be arranged on the stator and the fixed axis of external rotor inside, described stator is fastened on the fixed axis, two ends at fixed axis are equipped with bearing, and external rotor rotates by the bearing on the fixed axis; Feature is: described external rotor is formed by cast-aluminum rotor and cast aluminium shell cast solid, end cap is installed by hold-down screw in two ends at described external rotor, stretch out from end cap respectively at the two ends of described fixed axis, and skeleton rotary oil seal is installed between fixed axis and end cap; Be embedded with coil on described stator, be connected with lead-out wire on coil, lead-out wire passes from the through wires hole at fixed axis center, is filled with airtight and watertight padding between the through wires hole of the outer wall of lead-out wire and fixed axis.
Described end cap seam offers the groove that can hold seal on the plane, seals by seal between described external rotor and the end cap.
Described seal is fluid sealant or O RunddichtringO.Described fluid sealant adopts silicon rubber sealant.
Described airtight and watertight padding is an epoxide-resin glue.
The invention has the advantages that: can improve the outer rotor motor of degree of protection, simple structure, good looking appearance, no attachment device, low cost of manufacture.Lead-out wire waters envelope by epoxide-resin glue in fixed axis, external rotor and end cap be coating silicon rubber fluid sealant (or the O RunddichtringO is installed) in the groove of assembling mating surface, skeleton rotary oil seal is installed between fixed axis and end cap, can be improved the degree of protection of outer rotor motor effectively to IP66.
