Description
Technical field
This utility model relates to motor and technical field of generators, and in increasing motor particularly to one, cavity radiating is imitated
The band fan blade rotor connection structure of rate.
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.
Utility model content
The deficiency that this utility model designs for existing motor stator rotor internal cavity structure, it is provided that in a kind of increase motor
The band fan blade rotor connection structure of cavity radiating efficiency.
The purpose of this utility model is 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, a left side
Housing, left rotor, left rare earth permanent magnet block, stator, right rotor, right rare earth permanent magnet block, right shell body, connection ring set, radial air openings,
Fan blade, left shell is arranged on motor rotary shaft left end, left rotor right side and right rotor left side by bearing and glues respectively
Posting left rare earth permanent magnet block and right rare earth permanent magnet block, the endoporus of right rotor coordinates peace by driving key with motor rotary shaft cylindrical
Dress；Stator is arranged between left rotor and right rotor, and the upper part of stator is fixing with left shell and right shell body to be connected；Left rotor
Be equipped with positioning spigot on the left side of right side and right rotor, connect ring set fixed cover on positioning spigot, by left rotor and
Right rotor links together；In described left rotor, the external diameter of boring ratio motor rotary shaft is big, and the endoporus at left rotor turns with motor
Circular radiating vent passages is formed between the external diameter of axle；The cylindrical of described connection ring set has multiple radial air openings, connects ring
It is also equipped with fan blade on the cylindrical of set.
This utility model has a following beneficial effect:
In order to solve, the intrinsic stator rotor radiator structure of traditional rare earth permanent magnet motor is the most airtight not to dispel the heat this device
Problem, this device uses unique structure, can form, at stator and rotor internal cavity, the circulation canal that effectively dispels the heat, and ventilate
Mouthful sectional area is big, and vent passages is unimpeded, substantially increases radiating efficiency, additionally, connect ring set be provided with radial ventilation groove and
Fan blade, greatly improves the result of ventilating heat dissipation of motor.
