An object of the utility model is to provide a motor protector to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a motor protector, includes main shaft, skeleton sealing washer one, protection casing and O shape sealing washer, main shaft and end cover combination department are provided with skeleton sealing washer two, main shaft and protection casing combination department are provided with skeleton sealing washer one, the protection casing adopts threaded connection with the end cover tang, the protection casing is provided with the O shape sealing washer with end cover tang terminal surface, and this protector is rational in infrastructure, and the assembly is compact, but the wide application is in the motor that uses in the IP66 environment.

Preferably, a V-shaped sealing ring is arranged at the top of one end of the main shaft.

Preferably, the V-shaped sealing ring is arranged at one end of the bottom of the end cover.

Preferably, the framework sealing ring I and the framework sealing ring II are arranged close to each other.

Preferably, the protective cover is sleeved at the outer positions of the second skeleton sealing ring and the O-shaped sealing ring, so that a protective effect is achieved.

Preferably, the protection casing is used for protecting skeleton sealing washer one, skeleton sealing washer two and the whole axle of O shape sealing washer electrical equipment.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) This kind of motor protector through inside using after this protector at the motor and not discovering water and comdenstion water and entering into the motor, motor steady operation duration and life-span are showing and are improving, and the user reaction is good. The protection device has reasonable structure and compact assembly, and can be widely applied to motors used in cooling environments. The invention carries out a plurality of tests in a factory, and is used in a plurality of domestic markets, the reaction conditions are ideal, the design output can be achieved, and compared with the original waterproof structure, the waterproof performance can reach IP66;

(2) This kind of motor protector, through at a motor protector protection device include the protection casing structure, protection casing and end cover adopt threaded connection's mode, then protection casing and end cover combination department are equipped with O type sealing washer, protection casing and main shaft combination department adopt skeleton seal circle one sealed, and end cover and motor main shaft combination department are equipped with skeleton seal circle two, the cooperation realizes playing the work of leakproofness enhancement protective effect to the junction, this protection device is rational in infrastructure, the assembly is compact, but wide application is in the motor that uses in the IP66 environment.
