Embodiment

The utility model is explained in detail below in conjunction with the accompanying drawings.

The low Low noise cleaner motor that shakes of a kind of D types as shown in Figure 1, including electric machine casing 1 and in electric machine casing 1 Rotor core 2, stator core 3, determine impeller 4, movable vane wheel 5, fan housing 6 and commutator 7, in described rotor core 2 and Be respectively provided with winding on stator core 3, D type motor of dust collector transformed in order to reduce noise, it is original determine impeller 4 be by PA66+GF30 is made, and PA66+GF30 material is partially soft, causes the intensity deficiency of motor, and determines when in motor operation Impeller 4 is affected by temperature larger, and blade 9 easily deforms at high temperature, thus determine impeller 4 by BMC BMC one into Type is made；BMC BMC has an excellent mechanical performance, heat resistance it is strong and with it is excellent be chemical corrosivity, again Various moulding process are adapted to, so as to meet requirement of the motor of dust collector to performance, the intensity of motor of dust collector can be strengthened, are reduced Vibration, noise is reduced, noise is reduced to 100dB from original 102dB, and the air quantity of motor of dust collector adds 10.8%, from original 39.7m3/s increase to 44m3/s.

It is original that impeller 4 was determined using PA66+GF30, its insufficient strength thus to design its air channel smaller, in use, lead Cause the air quantity of motor of dust collector smaller, so that the temperature rise of motor of dust collector；It is fixed now to be strengthened using BMC BMC The intensity of impeller 4, so as to be redesigned to its air channel 10, the width in air channel 10 is adjusted to 2.1mm by original 1.8mm, Highly it is 6mm so that the air quantity increase of motor of dust collector, wind speed can be accelerated, so that temperature reduces.

The blade 9 for determining impeller 4 is designed as arc, and radian is outwards gradual change type from center, and its radian from center outwards by Gradual change is small, and specific blade 9 is integral type and combined by the radian section of 4 sections of different radians so that radian is rounder and more smooth, wind Stream is more smooth, flow increase, improves efficiency.

In original design, determine impeller 4 and be integrally fixed on support, and original support is to separate with electric machine casing 1 Shaping, used after assembling, and this mode fit precision is insufficient, easily causes larger vibration, it is existing in order to reduce vibration The use of determine impeller 4 with electric machine casing 1 is being integral type structure, is being not in precision not foot phenomenon, it is possible to reduce the behaviour of 2 processes Make, cost saved for company, the vibration values of motor can reduce by 28%, by original 20mm/s~25mm/s will be 13mm/s~ 18mm/s, due to cancelling support, air-flow directly blows to armature portion, and determines the air channel 10 of impeller 4 and widen, so that motor of dust collector Temperature in use reduces, and will be 76K by original 81K.

Rotor core 2 and stator core 3 are made using B35A300 silicon steel or 50W470 silicon steel, root According to performance of silicon steel itself, it is possible to increase the efficiency of motor.

To sum up, the low Low noise cleaner motor that shakes of D types effectively reduces the vibration of motor, and the vibration values of motor can reduce 28%, will be 13mm/s~18mm/s by original 20mm/s~25mm/s, the vibration of effective improvement motor of dust collector is big to ask Topic, reduce noise；Blade wheel structure is determined using integral type, air-flow blow-through armature, so as to cool, the production cost saved for company with And time cost.

It is emphasized that：It the above is only preferred embodiment of the present utility model, not the utility model appointed What formal limitation, every any simple modification made according to the technical essence of the utility model to above example, etc. With change and modification, in the range of still falling within technical solutions of the utility model.
