Abstract
The invention relates to an air way structure of a low-noise motor. The air way structure comprises a motor casing and is characterized in that a top casing is arranged on the upper portion of the motor casing and divided into a left air inlet chamber, a right air inlet chamber and a middle air outlet chamber by clapboards, wherein a first air inlet is formed in the end of the outer side of the left air inlet chamber, a second air inlet is formed in the end of the outer side of the right air inlet chamber, and a first air outlet is arranged on the upper portion of the air outlet chamber. A third air inlet and a fourth air inlet are arranged at two ends of the motor casing respectively, a second air outlet is arranged in the middle of the motor casing, clapboards are arranged in the left air inlet chamber and the right air inlet chamber, bent air flues are formed in the left air inlet chamber and the right air inlet chamber, the first air inlet and the second air inlet serve as the inlets of the air flues respectively, the third air inlet and the fourth air inlet serve as the outlets of the air flues respectively, and the second air outlet is communicated with the air outlet chamber. The special top casing is added, so that the air way can be effectively enlarged by the top casing and the clapboard structures in the top casing.
Description
Technical field
The present invention relates to a kind of wind path knot of low noise motor, especially a kind of wind path structure for high-low pressure Y-series low-noise three-phase asynchronous motor (as Y500-2-1250KW 6KV motor).
Background technology
To the improving constantly of environmental requirement, noise pollution is also the aspect that people are concerned about due to people.During original threephase asynchronous machine design, it is not so strict that noise is controlled, now a lot of clients are higher to the noise requirements of motor product, especially the requirement of 2P centrifugal motor is more increased, a lot of clients can propose noise sound lower than 85dB(A), also some customer requirement is higher, noise sound is lower than 80dB(A), this causes very large pressure for the design of electrical motor staff, also causes very large pressure to design cost simultaneously.
The noise of motor is relevant with several factors as everybody knows, as: the fan of motor, the wind path of electric motor fan, the temperature rise of motor etc.
Fig. 1 is the low noise wind path structure of existing threephase asynchronous center Y500-2-1250KW 6KV high-voltage motor, at the two ends of motor case 1a, air inlet 2a and air outlet 3a are set respectively, wind path is inner for entered motor case 1a by air inlet 2a, an end by rotor is delivered to the other end, then is sent by air outlet 3a.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of wind path structure of low noise motor is provided, increase effective wind path, reduce noise.
According to technical scheme provided by the invention, a kind of wind path structure of low noise motor, comprise motor case, motor shaft, stator, rotor and coil, feature is: the top at the motor case arranges overhead guard, overhead guard is become the air compartment that outes at left inlet air plenum, right inlet air plenum and middle part by baffle for separating, outboard end in left inlet air plenum arranges the first air inlet, in the outboard end of right inlet air plenum, the second air inlet is set, and on the top that goes out air compartment, the first air outlet is set; At the two ends of described motor case, the 3rd air inlet and the 4th air inlet are set respectively, at the middle part of motor case, the second air outlet are set; In described left inlet air plenum and right inlet air plenum, dividing plate is set, form respectively the air channel of bending in left inlet air plenum and right inlet air plenum, the import in air channel is respectively the first air inlet and the second air inlet, and the outlet in air channel is communicated with the 3rd air inlet and the 4th air inlet respectively; Described the second air outlet with go out air compartment and be communicated with, the first air outlet is in communication with the outside.
Be equipped with silencing cotton at the inner surface of described overhead guard and the surface of overhead guard internal partition.
The present invention is by increasing a special overhead guard, and the diaphragm structure in overhead guard and overhead guard can effectively increase wind path; And the silencing cotton in overhead guard effectively reduces noise.
