摘要

Methods and systems for grouping of media based on similarities between features of media data are provided. A method of managing a plurality of images may include: identifying a threshold distance for clustering the plurality of images based on a degree of similarity between the plurality of images; extracting a plurality of feature vectors corresponding to the plurality of images; and generating at least one cluster comprising at least two images among the plurality of images, based on cosine distances between feature vectors corresponding to the at least two images being less than the threshold distance.

说明书

[0001]无轴电机

[0002]技术领域

[0003]本实用新型涉及一种电机，特别是一种与泥浆泵配合使用的无轴电机。

[0004]背景技术

[0005]大型泥浆泵通常是在输入轴的两端分别通过传动机构与电机连接，即两部电机分别通过传动机构带动泥浆泵工作。这种结构存在的不足是：需要配置两套传动机构，包括联轴器、角带、电机带轮、输入轴带轮等，结构相对复杂，设备成本高；在电机轴与输入轴之间设置的传动机构大都为带传动，安装调试过程中，很难将两个角带的张紧度调整为完全一致，设备运行中容易出现两端驱动不同步，影响泥浆泵的正常工作，无法发挥泥浆泵使用效率；电机长时间运行，摩擦热量不能有效散发，影响其使用寿命，耗电量高。

[0006]发明内容

[0007]本实用新型的目的在于提供一种无轴电机，该电机可以直接与泥浆泵的输入轴连接，简化结构，降低制造成本，设有散热机构，运行稳定节能。

[0008]本实用新型的目的是这样实现的：一种无轴电机，包括：转子、定子、永磁体、机壳，其特征在于所述的转子内设安装空腔，外部依次设有转子辅铁、分布在转子辅铁外端的永磁块、定子以及机壳，机壳上两相对位置处分别设有通孔，其中一个通孔与吹风机连通，另一个通孔与吸风机连通。

[0009]在轮辐式转子的安装空腔内设有用于配合安装的稍套。

[0010]相对设置的吹风通孔与吸风通孔分别位于机壳的两侧，使进入机壳内的冷却空气从转子一侧进入到另一侧后再从吸风通孔排出。

[0011]本实用新型提供的电机不设输出轴，也省略了轴承室，电机结构简单，通过在电机转子上设置安装空腔，可以将电机直接安装在被驱动设备的轴上，为了安装方便，在安装空腔内可以设置能够方便更换稍套，通过调整不同内径的稍套，可使安装空腔与被驱动设备的不同轴紧密配合。在机壳上开通吹风和吸风通孔，通过电机外部的设备向电机内输送冷却空气，散热效果好，克服已有电机内设风扇散热效果差的问题，延长电机使用寿命，降低电机内部磁耗。

[0012]本实用新型的特点是：电机可以直接安装在被驱动设备上，省去设在电机与被驱动设备之间的传动机构，不但降低了被驱动设备的制造成本，还能克服因被驱动设备轴两端的传动机构张紧度不一致而不能同步运行的问题，设备转速同步，运转均衡，直连结构布局紧凑，减少占地面积。电机结构简单，制造成本低，安装拆卸方便，流通的空气散热，保证运转温度合理控制，散热效果好，电机运行安全平稳，节省电能。

[0013]附图说明

[0014]图1为本实用新型的结构示意图。

[0015]具体实施方式

[0016]下面结合附图对本实用新型作进一步详述：

[0017]如图所示，无轴电机主要由转子1、定子2、永磁块3、机壳4、内端盖5、外端盖6、吹风机7和吸风机8构成。轮辐式转子内有安装空腔，安装空腔内可以设置与其连接的稍套9，以使转子与泥浆泵的轴紧密配合。转子外部设转子辅铁10，在转子辅铁的外圆表面分布有按N、S级间隔均匀的永磁块，永磁块的外部有绕线定子，定子外部安装有机壳，机壳的两端分别固定连接内端盖和外端盖，内端盖靠设备止口固定在设备上。在机壳上设有两个相对设置的通孔11、12，其中吹风通孔11设在转子的内侧，与吹风机连通。吸风通孔12设在转子的外侧，与吸风机连通。工作时，由吹风机送入的冷却空气进入转子一侧的空间，再经转子辅铁孔隙进入转子另一侧的空间，然后由吸风机吸出，保证了电机部件的散热效果。
