当前,对生产批量很大的叠式绕组一般仍用手工嵌线,定子铁心嵌线一般在木制不可调的嵌线桌上进行,这种木桌高度是固定的,不适用于身高不同的操作者嵌线,嵌线时推动和翻转铁心很费力。转子嵌线在一对木制的支承架上进行,支承架与转轴之间的接触面积大,摩擦也大,转子铁心转动困难。木制结构强度差,操作安全不可靠。为此,设计制造了定、转子可调组合式嵌线桌,该桌适用范围广、省力、使用方便。现将该结构介绍如下。一、结构组合式嵌线桌由定子嵌线活动转盘、转子嵌线活动支承架和转椅三部分组成,见图(其中转椅部份在此省略)。各部分的结构分述如下: (1)定子嵌线桌上装有转盘,转盘和心轴连为一体,可作圆周运动和进行高度升降调节,转盘上装有两个滚轮,滚轮间距可调,间距调节范困视工件大小而定(调节范围适月jy系列Hso~315定子嵌线要求),桌旁挂有渣箩,桌面下部为工具柜, (2)转子嵌线活动支承架有2个(一对)位于定子嵌线桌旁,用铰链与定子嵌线桌上的桌架连接。每个支...&

国内的定子嵌线机分立式和卧式两种,均为“拉入法”嵌线。立式嵌线机为大连电机厂所采用,本刊已作介绍。下面简单报导上海跃进电机厂采用的卧式嵌线机。 嵌线机的外貌如图1。图中所示为正在嵌线的情况。图1定子嵌线机的外貌 嵌线原理:用与定子槽数相等的导指夹持导线,推头沿导指长度方向移动,从而把三相绕组拉入定槽中,即通常所说的“拉入法”嵌线。 嵌线机的主要结构有嵌线头和冲槽楔机构。 嵌线头机构主要由嵌线头(导指和推头)、槽楔箱和推槽楔座等组成,如图2所示。 嵌线机的结构示于图3。其动作过程为:冲槽楔机构把红钢纸槽楔冲入槽楔箱中,机械手把带线圈的嵌线头装在嵌线机上,定子铁心套入嵌线头并使导指伸出定子铁芯20一30毫米,推头和推槽楔座一起动作,把线圈和槽楔嵌到定子稽中。图2中表示出导指的形状。这里所用的线规是争1 .08毫米,为了减小导线在导指中的排线高度,导指间隙在设计制时控制在2.2毫米左右。 冲槽楔机构的作用,是把0 .8毫米厚的红钢纸成...&

一、概述 电机生产中利用手工嵌线,工时多、劳动强度大,历来是电机制造中的一大薄弱环节。 针对生产上的实际需要,我厂于去年n月份对分马力电机定子嵌线机进行了试制。经过对71一4极,56一4极,120瓦2极电机等几种产品的反复摸索和试验,使嵌线机结构、加工方法、绕组形式和嵌线工艺等方面不断得到了改进和完善。目前120瓦2极定子嵌线机已用于生产,经小批生产验证,嵌线的速度显著提高,质量也比较稳定,效果良好。 本嵌线机具有结构简单、制造容易、上马快和生产效率高的优点,不但适用于目前生产的120瓦2极三相分马力电机定子的嵌线,而且当冲片内径、槽数和槽口尺寸相同时,亦可适用于不同铁芯长度的2极及2极以上的单、三相分马力电机的定子嵌线。二、结构原理 本机的总体结构为立式,线圈拉入式。总体结构如图1。全机由导向条、顶线头(蘑菇头)、槽楔顶入装置、铁心推压机械手、油缸、液压阀体、电器操纵系统及床身等几部分组成。}—丫助-一一~一~;卜5一一二二、...&

目前在中小型电机制造中,嵌线大都采用手工,劳动强度大,占用工时多。为了改变这种情况,我国在1 958年就开始研制定子嵌线机。当时研究的是“直接绕嵌”法刀1962年已制成较完善的“直绕法”嵌线机。1971年又研制成较简单的“拉入法嵌线机”。在上海、大连、天津、沈阳等地相继试制推广。同时还试制了配套的绕线机、整形机、插槽绝缘机和端部绑扎机等设备。有些单位还试制了其他形式的嵌线机,例如电磁吸入法、绕嵌法、导片法嵌线机等。据不完全统计,目前已试制了嵌线机和配套设备共72台,投产使用的有48台。其中5号机坐以下的4极电机用拉入法嵌线比较成熟。现在将上海革新电机厂、大连电机厂和上海跃进电机厂应用情况简介如下: 一、上海革新电机厂从1972年便开始应用。目前已有嵌线机和配套设备共12台,生产油泵电机和分马力电机共八个规格,月产量2000台以上。 嵌线机采用拉入法嵌线。将绕好后的线圈套在导指间隙中,由推线头和槽楔推杆将线圈和槽楔拉入到定子槽中。...&

随着精纺面料产品更新换代,原来一色服装面料将逐渐转型。取而代之后是高支轻薄型和将不同颜色的毛纱用作嵌线交织在面料中,使精纺面料产生隐形或明显的条格,受到消费者的喜爱。嵌线顾名思义是将一根毛纱嵌在不同颜色的织物上,它的条干均匀要求很高,条干的粗节与细节或其他纱疵将会明显反映暴露出来。直接影响到面料的外观质量。如果选用涤纶嵌线,它的条干均匀度是好,但在生产应用中对织物布面容易引起吊径,并且影响呢面质量和手感风格。因此做好嵌线条干将显得更为迫切。根据嵌线特点,需从以下方面做好。1工艺设计与操作1.1由于嵌线条干均匀度要求高,首先必须保证粗纱条干CV值质量。结合车间自身生产设备优化工艺流程。同时,要考虑到牵伸倍数、并合次数、进条根数,又要预计到增加毛粒的工序。通过小样试验,对比最后确定纺纱工艺流程。1.2B412混条,B423头针,(OKK)ELE-6一针,HG-6(2C)二针,HG-6(2CW)三针,HFV-5(DAS)粗纱,FB44...&

借贵地问一个问题，因为我实在是找不到其它方式询问了，希望楼主不要介意。
我想发贴，但一直让我选择主题类别，找了半天找不到，是在哪里啊！

楼主的清单看上去太费劲，从概念上分析，单层同心式绕组与双层叠绕组的绕组系数不同，单层同心式的Kdp要大，另外二者端部长度不同，单层同心式端部要长，因此，电阻、电感参数会大不同。

空心杯电机斜绕组与同心式绕组性能分析　 0引言空心杯电机属于永磁直流伺服电机,它的结构特点在于电枢铁心上没有齿和槽,这种新颖的结构与等同条件下的齿槽电机相比具有输出功率密度大,转矩波动小,电气时间常数小,体积小、重量轻,转子转动惯量小,无齿槽效应,提高了电机的快速响应性能,使电机的运转特性得到了极大改善,具备了齿槽电机所无法达到的控制和拖动特性。因此,空心杯电机的应用越来越广泛。空心杯电机绕组电枢杯类型有多种:盘式绕组、直绕组、斜绕组、同心式绕组、叠绕组等。斜绕组以其绕线工艺简单易操作被广泛应用,国外两大知名空心杯电机生产公司德国某公司和瑞士某公司均采用斜绕组电枢杯,采用先进的绕线工艺技术,采用自动化设备一次性绕制成型,合格率100%,绕组杯平整度,一致性很好。近几年,瑞士某公司同时研发使用同心式绕组电枢杯,并号称该同心式绕组结构电机为“世界上最大功率密度电机”,同心式绕组电枢杯电机体积小、重量轻,可输出更大转矩的EC-POWER电机,国内尚未查到任何类似产品投入市场。本文分析了德国某公司和瑞士某公司斜绕组电枢杯的结构和工艺流程,重点剖析了瑞士某公司新提出的同心式绕组电枢杯的结构,从理论角度对绕组的切割磁场的有效长度、同样匝(本文共计3页)
