Abstract
The utility model provides an axial-flow fan motor which comprises a shaft of a motor, a stator, a rotor and two end covers. The utility model is characterized in that an outer rotor motor is adopted; one end cover is respectively fixedly connected with a shaft of the electric machine and the rotor, and the other end cover is fixedly connected with the stator. The motor has novel structure and light weight, the axial dimension is reduced by 60%, the weight is decreased by 30%, and material and space are saved, which leads the flow quantity of a fan to be increased and full pressure to be improved. In addition, the assembly is simple, the maintenance is easy, the operating performance is good, and the utility model is an ideal motor used by an axial-flow fan.
Description
Affiliated technical field
The utility model provides a kind of Axial-flow fan motor, belongs to technical field of motors.
Prior art
Traditional Axial-flow fan motor major part is that common electric machine is an inner rotor motor, the motor axial dimension is big, determined and to have had very long axial dimension by the series blower fan, waste material and space, this is obvious especially in the air-conditioning of size-constrained system, simultaneously motor fixedly is a difficult point, and simple insufficient strength is complicated and must influence flow, total head and the efficient of blower fan.
The utility model content
The purpose of this utility model provides a kind ofly can overcome above-mentioned defective, reduce the blower fan axial dimension, save material and parameters such as space, the flow that can increase blower fan and total head, improve the Axial-flow fan motor of fan efficiency.Its technology contents is:
Comprise motor shaft, end cap, stator and rotor, it is characterized in that: adopt external rotor electric machine, an end cap is connected to one with motor shaft, rotor respectively, and another end cap is fixedlyed connected with stator.
Described Axial-flow fan motor, motor shaft and end cap interference fit are integral, and this end cap and motor rotor die-casting are one, and another end cap and stator interference fit are one.
Its operation principle is: end cap of motor and stator transfixion, rotor and another end cap are that one is rotated round motor shaft.
This electric machine structure novelty, weight are light, reduce 60% than common electric machine axial dimension, weight saving 30%, and assembling is simple, and maintenance is installed on it on axial flow blower easily, and result of the test is to make compressor flow increase by 10%, and total head improves 5%.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
