Abstract
The utility model relates to a motor. The utility model is composed of a by stator core (4), a machine casing (5), a rotor (6) and an end cover (7), wherein, a sound absorption and vibration-proof layer (1) composed of elastic damping material is arranged between the machine casing (5) and the stator core (4); the connecting position of the end cover (7) and the machine casing (5) is provided with an elastic sound absorption mat (3); the interior of a pipe cavity of an axial through hole of the stator core (4) is filled and padded with sound absorption strips (2). The utility model stresses to eliminate a source which produces the noise, and the vibration is absorbed by the sound absorption layer, the sound absorption mat and the sound absorption strips; accordingly, the noise is completely absorbed, and the utility model becomes a noiseless motor.
Description
The utility model relates to a kind of motor, is a kind of noiseless motor.
In the conventional motors structure, between stator core and the casing, be connected for direct mechanical between end cap and the casing, during use, with rotor rotation, the noise of motor is directly delivered to outer surface, and the internal shape cavity of forward and backward end cap forms sound resonance by the axially extending bore tube chamber on the stator core simultaneously, makes motor noise bigger, cause environmental pollution, make the motor people around and feel tired brain.Solving motor noise is long-term next anxious technical barrier to be solved.
Task of the present utility model is to solve above-mentioned technical barrier, proposes a kind of noiseless motor.
The technical solution of the utility model is: a kind of motor is made of flexible damping material is formed between casing and stator core sound-absorbing, vibrationproof layer stator core, casing, rotor, end cap.At the flexible sound-absorbing pad of end cap and casing junction.
Owing to adopt such scheme, eliminated the noise that sends owing to vibration, collision between casing and the stator core, eliminate the noise source of original motor, make motor become the noiseless motor, finish the invention task.
Fig. 1 is embodiment of the present utility model.
Fig. 2 is the structure between end cap of the present utility model, casing.
Below in conjunction with accompanying drawing, be described in detail the utility model.
A kind of motor is made of flexible damping material is formed between casing (5) and stator core (4) sound-absorbing, vibrationproof layer (1) stator core (4), casing (5), rotor (6), end cap (7).At end cap (7) and the flexible sound-absorbing pad in casing (5) junction (3).In the axially extending bore tube chamber of stator core (4), fill and be lined with elasticity sound-absorbing bar (2).Elastic damping material can be rubber, elastoplast or flexible foam plastic.Sound-absorbing vibrationproof layer, pad, bar can be to be bonded in stator, end cap with soft glue, constitute glued construction (Fig. 1, Fig. 2) on axially extending bore tube chamber or the casing.
The utility model is conceived to eliminate the source that produces noise, absorbs vibration by sound absorbing layer, pad, bar, can eliminate noise fully, makes motor become the noiselessness motor.
Claims (3)
1, a kind of motor is made of stator core (4), casing (5), rotor (6), end cap (7), it is characterized in that: flexible damping material is formed between casing (5) and stator core (4) sound-absorbing, vibrationproof layer (1).
2, by the described motor of claim 1, it is characterized in that: at end cap (7) and the flexible sound-absorbing pad in casing (5) junction (3).
3,, it is characterized in that in the axially extending bore tube chamber of stator core (4), filling and be lined with elasticity sound-absorbing bar (2) by the described motor of claim 1.
