Description
Technical field
The present invention relates to motor and technical field of generators, particularly to a kind of motor inner chamber radiating efficiency of increasing
Band fan blade rotor connection structure.
Background technology
Disc-type electric motor can produce substantial amounts of heat in operation process, and this heat concentrates in motor case assembly for noise reduction,
Will build up on into harmful if can not discharge in time, have a strong impact on the service life of motor, cause motor temperature the highest and can not continue
Continuous normal work.Rare earth permanent magnet disc style motor, as common synchronization motor, is all made up of rotor and stator, has efficiently
Rate, High Power Factor, energy-saving effect outstanding feature, it is widely used.But rare earth permanent magnet disc style motor there is also
The rotor of permasyn morot heated up the problem such as high, although prior art part takes wind cooling temperature lowering measure, but
Its structure can not form the circulation canal that effectively dispels the heat so that enters the cold air in motor case assembly for noise reduction less, flowing speed
Spending unhappy, the thermal Finite taken away, cooling-down effect is the best, it is clear that for the rare-earth permanent magnet motor that caloric value is bigger, existing electricity
Aeration radiation system device within motivation particularly its inner rotator attachment structure can not reach and meet disk electric
The cooling requirement of machine.
Summary of the invention
The present invention is directed to the deficiency of existing motor stator rotor internal cavity structure design, it is provided that a kind of motor inner chamber that increases dissipates
The band fan blade rotor connection structure of the thermal efficiency.
It is an object of the invention to be achieved through the following technical solutions:
A kind of band fan blade rotor connection structure increasing motor inner chamber radiating efficiency, including motor rotary shaft, left shell,

Being equipped with positioning spigot on the left side of face and right rotor, connection ring set fixed cover is on positioning spigot, by left rotor and right-hand rotation
Son links together；In described left rotor, the external diameter of boring ratio motor rotary shaft is big, at endoporus and the motor rotary shaft of left rotor
Circular radiating vent passages is formed between external diameter；The cylindrical of described connection ring set has multiple radial air openings, connects ring set
Fan blade it is also equipped with on cylindrical.
The present invention has a following beneficial effect:
This device in order to solve the intrinsic stator rotor radiator structure of traditional rare earth permanent magnet motor the most airtight do not dispel the heat ask
Topic, this device uses unique structure, can form, at stator and rotor internal cavity, the circulation canal that effectively dispels the heat, and vent cuts
Area is big, and vent passages is unimpeded, substantially increases radiating efficiency, additionally, connect ring set to be provided with radial ventilation groove and fan
Blade, greatly improves the result of ventilating heat dissipation of motor.
