SATA转IDE的接线图及电气说明
SA TA转IDE，SA TA转其它接口的接线图及电气说明In computer hardware, Serial A TA (SATA, is a computer bus technology primarily designed for transfer of data to and from a hard disk. It is the successor to the legacy Advanced Technology Attachment standard (ATA, also known as IDE). This older technology was retroactively renamed Parallel A TA (PATA) to distinguish it from Serial ATA.The Serial A TA [SA TA] bus is defined over two separate connectors, one connector for the data lines and one for the power lines. A Serial A TA Hard drive may also have a third connector for legacy PATA power connections. The PA TA power connector may be used in instead of the SA TA power to supply a connection which is more rugged and reliable then the SA TA-1 power connection.The Serial A TA interface [SA TA] is the serial version of the IDE [A TA] spec. SA TA uses a 4 conductor cable with two differential pairs [Tx/Rx], plus an additional 3 grounds pins and a separate power connector. Data runs at 150MBps [1.5GHz] using 8B/10B encoding and 250mV signal swings, with a maximum bus length of 1 meter. SA TA enhancements move the data transfer speed to; 300MBps [3.0Gbps], and then 600MBps [6.0Gbps]. The current speed for SA TA is 300Mbps [3Gbps]. Shielded external SA TA [eSA TA] data cable runs out to a maximum of between 3 feet and 6 feet. eSATA cables are used external to the chassis or case.SATA Data pinoutSA TA PinOut,Signal Name Signal DescriptionData Pin #1GND Ground2A+ Transmit +3A- Transmit -4GND Ground5B- Receive -6B+ Receive +7GND GroundSATA Power pinoutSA TA PinOut,Signal Name Signal DescriptionPower Pin #1V33 3.3v Power2V33 3.3v Power3V33 3.3v Power, Pre-charge, 2nd mate4Ground 1st Mate5Ground 2nd Mate6Ground 3rd Mate7V5 5v Power, pre-charge, 2nd mate8V5 5v Power9V5 5v Power10Ground 2nd Mate11Reserved -12Ground 1st Mate13V12 12v Power, Pre-charge, 2nd mate14V12 12v Power15V12 12v PowerPATA Power pinoutIDE Power Connector Pin OutPin #Signal Function18 A WG Wire1+12V DC Y ellow2+12V Return Black3+5V Return Black4+5V DC RedSATA signal names are with respect to the Host, the device connected to the host reverses the signal names. Transmit pins connect to Receive pins on the other device. The SA TA connector is keyed at pin 1. These pin outs for the Serial A TA connector are not compatible with the legacy PA TA connector.[The following article is licensed under the GNU Free Documentation License. It reproduces the Wikipedia article "Serial ATA"]SATA 1.5 Gb/sFirst-generation Serial A TA interfaces, also known as SA TA/150, run at 1.5 Gigahertz (GHz). Serial ATA uses 8B/10B encoding at the physical layer. This encoding scheme has an efficiency of 80%, resulting in an actual data transfer rate of 1.2 Gigabits per second (Gb/s), or 150 megabytes per second (MB/s). The relative simplicity of a serial link and the use of LVDS allow both the use of longer drive cables and an easier transition path to higher speeds.SATA 3.0 Gb/sSoon after SA TA's introduction, enhancements were made to the standard. A 3Gb/s signalling rate was added to the PHY layer, offering up to twice the data throughput. To ensure seamless backward compatibility between older SA TA and the newer faster SATA/3Gbs devices, the latter devices are required to support the original 1.5Gb/s rate. In practice, some older SA TA systems that do not support SA TA speed negotiation require the peripheral drive's speed be manually hardlimited to 150Â MB/s with the use of a jumper for a 300Â MB/s drive.Like SA TA 1.5Gb/s, SA TA 3Gb/s uses 8B/10B encoding resulting in an actual data transfer rate of 2.4 Gb/s, or 300 MB/s.The 3.0Â Gb/s specification has been very widely referred to as “Serial A TA II” (“SA TA II”), contrary to the wishes of the Serial A TA standards organization that authored it. The official website notes that SA TA II was in fact that organization's name at the time, the SA TA 3Gb/s specification being only one of many that the former SATA II defined, and suggests that “SA TA 3Gb/s” be used instead. (The Serial A TA standards organization has since changed names, and is now “The Serial A TA International Organization”, abbreviated SA TA-IO.)SATA-IO plans to further increase the maximum throughput of Serial A TA to 600ÂMB/s around the year 2007.SATA 3Gb/s is sometimes also referred to as SA TA/300 or SA TA II, continuing the line of PA TA/100, PA TA/133 and SA TA/150.SATA 6.0 Gb/sSATA-IO plans to make a 6.0 Gb/s standard. Although the theoretical thoroughput would be doubled, conventional hard disks can't approach saturating this speed.Serial ATA innovationsSATA drops the master/slave shared bus of PATA, giving each device a dedicated cable and dedicated bandwidth. While this requires twice the number of host controllers to support the same number of SA TA devices, at the time of SA TA's introduction this was no longer a significant drawback. Another con troller could be added into a controller ASIC at little cost beyond the addition of the extra seven signal lines and printed circuit board (PCB) space for the cable header.Features allowed for by SATA but not by PA TA include hot-swapping and native command queueing.To ease their transition to SA TA, many manufacturers have produced drives which use controllers largely identical to those on their PA TA drives and include a bridge chip on the logic board. Bridged drives have a SATA connector, may include either or both kinds of power connectors, and generally perform identically to native drives. They may, however, lack support for some SA TA-specific features. As of 2004, all major hard drive manufacturers produce either bridged or native SATA drives.SATA drives may be plugged into Serial Attached SCSI (SAS) controllers and communicate on the same physical cable as native SAS disks. SAS disks, however, may not be plugged into a SA TA controller.Cables and ConnectorsPhysically, the SA TA power and data cables are the most noticeable change from Parallel A TA. The SA TA standard defines a data cable using seven conductors and 8Â mm wide wafer connectors on each end. SA TA cables can be up to 1 m (39 in) long. PA TA ribbon cables, in comparison, carry either 40- or 80-conductor wires and are limited to 46 cm (18 in) in length. The reduction in conductors makes SA TA connectors and cables much narrower than those of PATA, thus making them more convenient to route within tight spaces and reducing obstructions to air cooling. Unlike early PATA connectors, SA TA connectors are keyed — it is not possible to install cable connectors upside down without considerable force.The SA TA standard also specifies a power connector sharply differing from the four-pin Molex connector used by PATA drives and many other computer components. Like the data cable, it is wafer-based, but its wider 15-pin shape should prevent confusion between the two. The seemingly large number of pins are used to supply three different voltages if necessary — 3.3Â V, 5Â V, and 12Â V. Each voltage is supplied by three pins ganged together (and 5 pins for ground). This is because the small pins cannot supply sufficient current for some devices, so they are combined. One pin from each of the three voltages is also used for hotplugging. The same physical connections are used on 3.5-in (90mm) and 2.5-in (70mm) (notebook) hard disks. Some SATA drives include in PA TA style four-pin Molex connector for use with power supplies that lack the SA TA power connector. Also, adaptors are available to convert a PATA style power connector to SA TA power connector.External SATAeSA TA was standardized in mid-2004, with specifically defined cables, connectors, and signal requirements for external SA TA drives. eSATA is characterized by:∙Full SA TA speed for external disks (115MB/s have been measured with external RAID enclosures) ∙No protocol conversion from IDE/SA TA to USB/Firewire, all disk features are available to the host ∙Cable length is restricted to 2m, USB and Firewire span longer distances.∙Minimum and maximum transmit voltage decreased to 400mV - 500mV∙Minimum and maximum receive voltage decreased to 240mV - 500mVUSB and Firewire require conversion of all communication with the external disk, so external USB/Firewire enclosures include an IDE or SA TA bridge chip that translates from the A TA protocol to USB or Firewire. Drive features like S.M.A.R.T. cannot be exploited that way and the achiveable transfer speed with USB/Firewire is only about half of the entire bus data rate of about 50MB/s. This limited effective data transfer rate becomesvery visible when using an external RAID array and also with fast single disks which may yield well over 70MB/s during real use.Currently, most PC motherboards do not have an eSA TA connector. eSATA may be enabled through the addition of an eSA TA host bus adapter (HBA) or bracket connector for desktop systems or with a Cardbus or ExpressCard for notebooks.Note:Prior to the final specification for eSATA, there were a number of products designed for external connections of SA TA drives. Some of these use the internal SA TA connector or even connectors designed for other interface specifications, such as IEEE 1394. These products are not eSA TA compliant.eSA TA does not provide power, which means that external 2.5" disks which would otherwise be powered over the USB or Firewire cable need a separate power cable when connected over eSA TA.eSATA compared to other buseseSA TA PA TA Fire Wire 1394b USB 2.0 Actual Speed 2.4 >Gib/s 1064 Mib/s 786 Mib/s ~375 Mib/sMax. cable length 2 meters 46 centimetres 4.5 meters 16 cables canbedaisy chained up to 72meters5 metersPower cablerequired?Y es Y es No NoDevices per Channel 1 (5 withmultiplier)3 (3rd device readonly)63 127Backward compatibilityThe backward compatibility of SATA hard discs is virtually non-existent in the sense that SA TA drives will not work with the same connectors that IDE, SCSI, or any other format of hard drive connect to. It is, however, possible to purchase convertors that attach to the rear of the SA TA hard disc and will allow it to function as an IDE drive. This can prove useful in situations where one wishes to use their SA TA drive on older motherboards that may not have SATA connections, etc.SATA vs SCSISCSI currently offers transfer rates higher than SA TA, but is a more complex bus usually resulting in higher costs to the user. Some drive manufacturers offer longer warranties for SCSI devices, however, indicating a possibly higher manufacturing quality control of SCSI devices compared to PATA/SA TA devices.。

三相异步电动机接线图及正反转接线实图讲解，一定要及时看
三相异步电动机接线图及正反转接线实图讲解，一定要及时看电工常见问题分享解答2019年12月11日关注三相异步电动机接线图及正反转接线实图讲解，三相异步电机，是感应电动机的一种，是靠同时接入380V三相交流电流（相位差120度）供电的一类电动机，由于三相异步电动机的转子与定子旋转磁场以相同的方向、不同的转速成旋转，存在转差率，所以叫三相异步电动机。
三相异步电动机转子的转速低于旋转磁场的转速，转子绕组因与磁场间存在着相对运动而产生电动势和电流，并与磁场相互作用产生电磁转矩，实现能量变换。
与单相异步电动机相比，三相异步电动机运行性能好，并可节省各种材料。
按转子结构的不同，三相异步电动机可分为笼式和绕线式两种。
笼式转子的异步电动机结构简单、运行可靠、重量轻、价格便宜，得到了广泛的应用，其主要缺点是调速困难。
绕线式三相异步电动机的转子和定子一样也设置了三相绕组并通过滑环、电刷与外部变阻器连接。
调节变阻器电阻可以改善电动机的起动性能和调节电动机的转速。
三相异步电动机的工作原理当向三相定子绕组中通入对称的三相交流电时，就产生了一个以同步转速n1沿定子和转子内圆空间作顺时针方向旋转的旋转磁场。
由于旋转磁场以n1转速旋转，转子导体开始时是静止的，故转子导体将切割定子旋转磁场而产生感应电动势（感应电动势的方向用右手定则判定）。
由于转子导体两端被短路环短接，在感应电动势的作用下，转子导体中将产生与感应电动势方向基本一致的感生电流。
转子的载流导体在定子磁场中受到电磁力的作用（力的方向用左手定则判定）。
电磁力对转子轴产生电磁转矩，驱动转子沿着旋转磁场方向旋转。
通过上述分析可以总结出电动机工作原理为：当电动机的三相定子绕组（各相差120度电角度），通入三相对称交流电后，将产生一个旋转磁场，该旋转磁场切割转子绕组，从而在转子绕组中产生感应电流（转子绕组是闭合通路），载流的转子导体在定子旋转磁场作用下将产生电磁力，从而在电机转轴上形成电磁转矩，驱动电动机旋转，并且电机旋转方向与旋转磁场方向相同。
