A kind of band fan blade rotor connection structure increasing motor inner chamber radiating efficiencyTechnical field
The present invention relates to motor and technical field of generators, particularly to a kind of motor inner chamber radiating efficiency of increasingBand 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 continueContinuous normal work.Rare earth permanent magnet disc style motor, as common synchronization motor, is all made up of rotor and stator, has efficientlyRate, High Power Factor, energy-saving effect outstanding feature, it is widely used.But rare earth permanent magnet disc style motor there is alsoThe rotor of permasyn morot heated up the problem such as high, although prior art part takes wind cooling temperature lowering measure, butIts 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 speedSpending 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 electricityAeration radiation system device within motivation particularly its inner rotator attachment structure can not reach and meet disk electricThe 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 dissipatesThe 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,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, fanBlade, left shell is arranged on motor rotary shaft left end, left rotor right side and right rotor left side by bearing and is pasted with respectivelyLeft rare earth permanent magnet block and right rare earth permanent magnet block, the endoporus of right rotor coordinates installation by driving key with motor rotary shaft cylindrical；FixedSon 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；The right-hand member of left rotorBeing 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 rotationSon 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 rotorCircular radiating vent passages is formed between external diameter；The cylindrical of described connection ring set has multiple radial air openings, connects ring setFan 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 askTopic, this device uses unique structure, can form, at stator and rotor internal cavity, the circulation canal that effectively dispels the heat, and vent cutsArea is big, and vent passages is unimpeded, substantially increases radiating efficiency, additionally, connect ring set to be provided with radial ventilation groove and fanBlade, greatly improves the result of ventilating heat dissipation of motor.
