本发明属于电动机技术领域，涉及一种散热装置、无刷电机转子结构和散热控制器。
背景技术
房屋装修过程中，粉刷墙面是至关重要的装修内容，而对粉刷后的墙面精细打磨提高墙面的平整度又是必不可少的一不，但是在传统的打磨过程中，会产生很多粉尘，为了减少粉尘；
而现有的墙面打磨机中的电机直接与打磨盘连接，而现有的电机一般通过壳体包裹定子和转子组成，该电机在工作时会产生大量的热量，且电机外侧通常设有外壳，电机产生的热量难以快速的通过壳体和外壳传递至外界空气中，从而使得电机在工作时电机的工作温度较高，使得电机无法长时间的持续工作，使得墙面打磨效率降低。
目前，电机转子是直流电机的核心部件，它通过永磁体实现力的传递，在电机工作时，电机转子不但承受传递力的冲击，而且还承受转子高速旋转时产生的离心力，因此，转子的结构优劣直接影响直流电机的性能和寿命。传统的无刷永磁大功率电机转子上的永磁体与转子铁芯之间一般通过胶粘剂固定，采用该结构简单实用、生产加工方便，但不足之处是由于受电机长期运转产生温度变化以及胶粘剂自然老化的影响，永磁体与转子铁芯之间的粘接力慢慢产生退化，在电机高速旋转产生的离心力作用下，永磁体就会产生脱落，造成电机故障，无法正常运转。
现有的墙面打磨机的控制器内一般设有较多的功率元件，这些功率元件在进行正常工作时通常会产生大量的热量，而由于控制器一般外侧包裹有外表壳，外表壳上通常只设有较小的透气孔，所以现有的 打磨机控制器在使用时发热严重，在长时间工作后控制器通常需要一定时间的停机降温，这大大影响了墙面打磨的工作效率。

固定座50-3设有螺纹座55，螺纹座55位于固定座50-3下端的前后两侧，螺纹座55内侧设有固定螺钉56，固定螺钉56穿过螺纹座55螺纹连接在散热块53内，本实施例通过固定螺钉56对散热块53进行固定，使得散热块53的安装方便、快速。

本发明在使用时，电路板50-2上的功率元件54在工作时会产生大量的热量，热量则相应的传递至散热块53，散热块53中的热量则传递至紧贴的空心手柄2内，空心手柄2内在使用时用于抽吸和输送粉尘，空心手柄2内空气流动快，空心手柄2内的热量则快速的传递至流动的空气中，并随着空心手柄2排出至空心手柄2外侧，从而实现控制器主体的快速散热。
本实施例的散热控制器也可单独运用于现有设备。
双轴电机3包括散热装置、定子3-2和位于定子3-2内侧的转子3-3，定子3-2设置于机座3-1内部，机座3-1与机壳1固设连接，机座3-1隔离机壳1和定子3-2。
散热装置包括机座3-1和散热风扇3-4，机座3-1包括散热翅片3-8，相邻散热翅片3-8之间形成散热气道，散热气道以及散热风扇3-4形成散热路径，气体沿散热路径流通。
机座3-1将双轴电机3的定子3-2和转子3-3与机壳1分隔，定子3-2和转子3-3运行产生的热量传递至机座3-1，气体沿散热路径快速流通将热量带走，从而加快电机装置的散热速度，降低电机装置2在使用时的使用温度。
机座3-1外表面设置若干散热翅片3-8，若干散热翅片3-8沿机 座3-1的圆周方向依次分布，相邻散热翅片3-8之间构成散热气道，空气沿散热气道流通。
散热风扇3-4设置在转子3-3下端并位于电机座8上端，机座3-1包括位于散热风扇3-4外侧的吸气座3-1-1和位于吸气座3-1-1上侧的散热座3-1-2，吸气座3-1-1左右两侧设有与散热风扇3-4连接的出风口3-5，散热风扇3-4与定子3-2之间设有安装在散热座3-1-2内侧的分隔层3-6，分隔层3-6内侧中心位置设有位于转子3-3外侧的通道孔3-7，分隔层3-6将散热风扇3-4与定子3-2隔离，避免长时间工作后散热风扇3-4受热变形。

散热片131包括吸气部和导气部，导气部高度大于吸气部高度，根据图3的视觉角度，吸气部的前端面(与气体直接碰撞的端面)设置为弧形面，在散热风扇3-4转动过程中，气体流通至吸气部，通过吸气部的弧形面对气体进行分流和导向，使气体沿导气部流通至散热区进行散热；本实施例吸气部和导气部高度差的设置使气体大部分先与吸气部碰撞，经碰撞的气体改变流通方向，并降低了流速，散热片131设为弯曲结构，延长了气体在散热片131的流通路径，散热片131转动后，在离心力作用下，气体沿导气部流通至散热区，并向外流通排出至外部空间。
吸气座3-1-1设置进风口3-9，进风口3-9位于相邻散热翅片3-8之间与散热气道连通，且位于吸气座3-1-1和散热座3-1-2之间，分隔层3-6外侧设有与进风口3-9和散热风扇3-4连通的衔接孔3-10，本实施例通过双轴电机3带动散热风扇3-4转动，在散热风扇3-4的作用下将外界空气从机座3-1外侧吸入并依次经过进风口3-9和衔接孔3-10进入散热风扇3-4内，从而加快机座3-1外侧的空气流动，加快机座3-1和散热翅片3-8与外界空气的热交换，热交换后的空气通过出风口3-5将排出，从而加快机座3-1的散热速度，降低双轴电机3在使用时的使用温度。
本实施例中散热风扇3-4在转动吸收外界空气时，空气沿散热气道流动并通过进风口3-9和衔接孔3-10进入散热风扇3-4内，从而使得吸入的流动空气与机座3-1以及散热翅片3-8持续接触进行热交换，从而大大降低机座3-1在使用时的温度。
转子3-3包括转轴26、转子铁芯27、定位架29、永磁体28和固定套32，转子铁芯27固设在转轴26外侧，定位架29固设在转子铁芯27外侧，永磁体28固设在定位架29外侧。

无刷电机转子结构还包括限位座31，限位座31设置一对，一对限位座31分别固设在转子铁芯27的两端，一对限位座31分别与永磁体28贴合设置，从而对永磁体28在轴向进行限位。
固定套32套设在永磁体28外侧，固定套32将永磁体28包裹在其内部，固定套32的内表面与永磁体28的外表面贴合设置，从而对永磁体28在径向进行限位，避免永磁体28在使用过程中脱出，避免永磁体在转动过程中发生移动，使得转子的定位更加的准确，不同永磁体所处于的磁场强度相同，从而保证转子的输出功率。
如图2所示，相邻永磁体28与固定套32形成空腔321，空腔321用于涂抹粘剂，将永磁体28与固定套32进行固定，本实施例中空腔321位于永磁体28侧面，相较于现有在永磁体28外侧面涂抹粘剂，本实施例通过将粘剂涂抹在永磁体28侧面，有效避免影响永磁体28的工作性能。
本实施例中，通过固定套隔离永磁体28和定子3-2，大大缩短 了转子与定子之间的距离，从而加强了磁场强度以及转子切割磁感线时产生的机械能。
本实施例中，固定套32设置为无缝钢管。
本实施例中，通过在定位架29设置间隔条30对永磁体28在圆周方向进行限位，通过一对限位座31对永磁体28在轴向进行限位，通过固定套32对永磁体28在径向进行限位，实现了永磁体28与转子铁芯27的稳定安装，相较于现有胶粘剂固定导致的永磁体脱落问题，本实施例通过结构改进保证永磁体28安装的稳定性。

显然，所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
