如何进行直线电机选型直线电机选型——最大推力和持续推力计算目录直线电机选型 (2)——最大推力和持续推力计算 (2)概述 (4)三角模式 (4)梯形模式 (5)持续推力 (5)计算公式 (5)例子 (6)概述直线电机的选型包括最大推力和持续推力需求的计算。
最大推力由移动负载质量和最大加速度大小决定。
推力 = 总质量 x 加速度 + 摩擦力 + 外界应力例子：当移动负载是2.5千克（包含动子），所需加速度为30m/s²时，那么，电机将产生75N的力（假设，摩擦力和外界应力忽略不计）。
通常，我们不知道实际加速度需求，但是，我们有电机运行实际要求。
给定的运行行程距离和所需要的行程时间，由此可以计算出所需要的加速度。
一般来说，对于短行程，推荐使用三角形速度模式，即无匀速运动，长行程的话，梯形速度模式更有效率。
在三角形速度模式中，电机的运动是没有匀速段的。
三角模式加速度为Acceleration = 4 x Distance / Travel_Time²梯形模式需要提前设置匀速的速度值，由此可以推算出加速度。
加速度 = 匀速 / （运动时间–位移 / 匀速）同理，减速度的计算与加速度的计算是类似的，特殊情况是存在一个不平衡的力（例如重力）作用在电机上。
通常情况下，为了维持匀速过程和停滞阶段，摩擦力和外界应力也要考虑进来，为了维持匀速，电机会对抗摩擦力和外界应力，电机停止时则会对抗外界应力。
持续推力计算公式持续推力的计算公式如下：RMSForce = 持续推力Fa = 加速度力Fc = 匀速段力Fd = 减速度力Fw = 停滞力Ta = 加速时间Tc = 匀速时间Td = 减速时间Tw = 停滞时间又最大推力和持续推力进行电机的选择。
一般情况下，应该将安全系数设置为20~30%，从而抵消外界应力和摩擦力。
例子电机需要在三角模式下，在0.2秒内，把4kg的负载移动0.3米。
电机在同行程中，返程之前停滞时间为0.15秒。

葆德电气公司与节能
葆德电气公司最宝贵的优良传统就在于能够始终不渝地探索如何 提高能源效率。1920年，葆德公司的创始人就提出他们将“建造 能源消耗最低的优质电机”来服务全球，在过去的80年里，葆德 一直率领整个行业不断研发性能更加优越、可靠性更高、能源消 耗更低的机电产品。从20世纪20年代成立公司至今，葆德已经发 起并推出了一系列节能改进措施，它们最终成为了行业标准。 随着电力成本的不断上升，如何提高电动机和驱动器等产品 的能效问题变得日益重要。 各家企业都必须在能源成本不断上升、可用电力日益不确定 的 环境中提高自己的竞争力，而同时全球各地对碳排放量的 严格管理也要求机械设备和生产过程所消耗的能源必须比过 去更 低。这些举措要求工业电机、驱动器以及发电机供应商 必须具有前瞻思想，能够预知用户的需求以生产既能节约成 本又能提高产量的机电产品。无疑葆德公司就是其中之一。 提高2.75个百分点、损耗平均下降20％左右，则每年可节约 电能160亿千瓦时。如果考虑其中的30％的电机运行在6000 小时以上的场合，将这部分电机改用超高效率电机，即效率 再提高1.5~2个百分点，损耗平均下降15％左右，则可再节 约电能46亿千瓦时，相应可再节约170万吨标煤，约合240 万吨原煤。并可再节约一座100万千瓦电站的投资建设。 许多国家针对电动机都已经制定了各自的《最低能效标准 （MEPS）》，这些标准将决定各个国家电机的最低能效。 在北美、巴西、加拿大、中国、马来西亚、澳大利亚、新西 兰以及墨西哥等国已经实施了MEPS，而世界上其他国家和 地区也正在制定各自的MEPS标准。随着人们对碳排放问题 日益关注，可以预见在不久的将来绝大多数国家都将会执行 MEPS，而欧盟已经达成了自愿协议，并正在讨论MEPS将 执行怎样的目标能效等级。

Add or remove shims between cap and base as requiredto obtain “snug” fit of unit in outer housing with cap bolts tightened to specified torque in Table 1.5. Check fit by prying against lubrication stud in unit throughthe lubrication hole in housing cap with a screwdriver or small pinch bar depending upon the size of the pillow blocks.6. The “snug” fit becomes a matter of judgment. A “loose orsloppy” fit may allow a unit mount to move in its outer housing thus wearing the mating surfaces. Too “tight” a fit will not allow the unit to move and compensate for misalignment and for shaft deflection caused by belt pull and dead weight.7. Install bearings per installation instructions contained in thismanual.INSTALLATION INSTRUCTIONS1. Shaft must be clean, free of burrs and lubricated. File nicksfrom housing bases.2. Loosen setscrews in collar and slide bearings on shaft. Ifforce is necessary, tap inner race only with a light drift. For vertical applications, locate adjusting nut on bearing so nut faces upward.3. Position expansion (floating) pillow block on mountingsurface and tighten base hold-down bolts.4. Position non-expansion (fixed) pillow block in correct relationto shaft and mounting surface. Tighten base holddown bolts, then torque setscrews in collar per Table 2.5. The effort required to turn the shaft should be the samebefore and after bolting bearings to the support.Table 2 – Set Screw TorqueBore Size (In)Set Screw Size (In)In-Lbs 1-3/16 – 1-11/165/161651-3/4 – 2-1/23/82902-11/16 – 3-1/21/26203-15/16 – 55/813255-7/16 – 63/421506-7/16 – 77/851306.

The expansion (floating) bearing is now installed.LUBRICATION GUIDELINESThis bearing is factory lubricated with a lithium or lithium complex base grease which is suitable for most applications. However, extra protection is necessary if the bearing is subjected to excessive moisture, dust, corrosive vapor or other harsh environments. In these cases, the bearing should contain as much grease as speed will permit (a full bearing with consequent slight leakage through the seal is the best protection against contaminant entry).For relubrication, select a grease that is compatible with a lithium or lithium complex grease. The following table is a general guide for normal operating conditions. However, some situations may require a change in lubricating periods as dictated by experience.Normal Operation — This bearing has been greased at the factory and is ready to run. The following table is a general guide for relubrication. However, certain conditions may require a change of lubricating periods as dictated by experience. See “High Speed Operation” and “Operation in Presence of Dust, Water or Corrosive Vapors” above.High Speed Operation — High speed operation is 70% of maximum catalog speed and above. In the higher speed ranges too much grease will cause overheating. The amount of grease that the bearing will take for a particular high speed application can only be determined by experience — see “Operating Temperature” below. If excess grease in the bearing causes overheating, it will be necessary to remove grease fitting (also drain plug when furnished) to permit excess grease to escape. The bearing has been greased at the factory and is ready to run. When establishing a relubrication schedule, note that a small amount of grease at frequent intervals is preferable to a large amount at infrequent intervals.Operation in Presence of Dust, Water or Corrosive Vapors — Under these conditions the bearing should contain as much grease as speed will permit, since a full bearing with consequent slight leakage is the best protection against entrance of foreign material. In the higher speed ranges too much grease will cause overheating — see “High Speed Operation” above. In the lower speed ranges it is advisable to add extra grease to a new bearing before putting into operation. Bearings should be greased as often as necessary (daily if required) to maintain a slight leakage at the seals.Operating Temperature — Abnormal bearing temperature may indicate faulty lubrication. Normal temperature may range from a few degrees up to 100ºF above ambient, depending on bearing size, speed, loading and environmental conditions. Unusually high temperature, in this range, accompanied by excessive leakage of grease indicates too much grease. In the circumstance that there is excess grease in the bearing, remove the grease fitting to allow the excess grease to purge. When purging ceases, wipe excess grease with a clean rag and screw fitting back into the bearing. High temperature with no grease showing at the seals, particularly if the bearing seems noisy, usually indicates too little grease. Normal temperature and a slight showing of grease at the seals indicate proper lubrication.Table 4 – Lubrication Guide Read Preceding Paragraphs Before Establishing Lubrication ScheduleHours Run per Day Suggested Lubrication Period In Weeks 1 to 250RPM 251 to 500RPM 501 to 750RPM 751 to 1000RPM 1001 to 1500RPM 8162412121012751053742521Lubrication recommendations are intended for standard products applied in general operating conditions. For modified products, high temperature environments and other anomalous applications, contact product engineering at 864.284.5700.Kind of Grease — Many ordinary cup greases will disintegrate at speeds far below those at which DODGE bearings will operate successfully if proper grease is used. DODGE bearings have been lubricated at the factory with an NLGI #2 lithium complex base grease. Relubricate with lithium complex-base grease or a grease which is compatible with original lubricant and suitable for roller bearing service. In unusual or doubtful cases the recommendation of a reputable grease manufacturer should be secured.Storage or Special Shutdown — If exposed to wet or dusty conditions or to corrosive vapors, extra protection is necessary. Add grease until it shows at the seals; rotate the bearing to distribute grease; cover the bearing. After storage or idle period, add a little fresh grease before running. During long idle periods, rotate shaft at least once a month.Special Operating Conditions — Refer acid, chemical, extreme or other special operating conditions to Baldor Electric Company.。

美国葆德Baldor各种电机的工作原理及应用
美国葆德Baldor各种电机的工作原理及应用一、伺服电动机伺服电动机广泛应用于各种控制系统中，能将输入的电压信号转换为电机轴上的机械输出量，拖动被控制元件，从而达到控制目的。
伺服电动机有直流和交流之分：早的伺服电动机是一般的直流电动机，在控制精度不高的情况下，才采用一般的直流电机做伺服电动机。
目前的直流伺服电动机从结构上讲，就是小功率的直流电动机，其励磁多采用电枢控制和磁场控制，但通常采用电枢控制。
直流伺服电动机在机械特性上能够很好的满足控制系统的要求，但是由于换向器的存在，存在以下不足：换向器与电刷之间易产生火花，干扰驱动器工作，不能应用在有可燃气体的场合电刷和换向器存在摩擦，会产生较大的死区结构复杂，维护比较困难交流伺服电动机本质上是一种两相异步电动机，其控制方法主要有三种：幅值控制、相位控制和幅相控制。
一般地，伺服电动机要求电动机的转速要受所加电压信号的控制；转速能够随着所加电压信号的变化而连续变化；电动机的反映要快、体积要小、控制功率要小。
二、步进电动机所谓步进电动机就是一种将电脉冲转化为角位移的执行机构。
更通俗一点讲：当步进驱动器接收到一个脉冲信号，它就驱动步进电机按设定的方向转动一个固定的角度。
我们可以通过控制脉冲的个数来控制电机的角位移量，从而达到定位的目的；同时还可以通过控制脉冲频率来控制电动机转动的速度和加速度，从而达到调速的目的。
目前，比较常用的步进电动机包括反应式步进电动机（VR）、永磁式步进电动机（PM）、混合式步进电动机（HB）和单相式步进电动机等。
步进电动机和普通电动机的区别主要就在于其脉冲驱动的形式，正是这个特点，步进电动机可以和现代的数字控制技术相结合。
但步进电动机在控制精度、速度变化范围、低速性能方面都不如传统闭环控制的直流伺服电动机；所以主要应用在精度要求不是特别高的场合。
由于步进电动机具有结构简单、可靠性高和成本低的特点，所以步进电动机广泛应用在生产实践的各个领域；尤其是在数控机床制造领域，由于步进电动机不需要A/D 转换，能够直接将数字脉冲信号转化成为角位移，所以一直被认为是理想的数控机床执行元件。

概况
什么是直线伺服电机？
科尔摩根公司 PLATINUM® DDL 系列电机是无框架三相永磁 无刷伺服电机。在结构上，直线电机是由一台旋转电机沿 径向剖开，拉直演变而成。
反馈类型：
所有无刷电机均需要用于换向的反馈。常规旋转电机通常 利用一个安装在电机后面的旋变或一体化安装在线圈绕组 上的霍耳效应装置。对于一台直线电机，也可通过各种方 法实现换向反馈。 科尔摩根公司可提供适合 PLATINUM® DDL 系列直线电机的数字型或线性霍耳效应装置，与旋转 电机一样，驱动电子器件实现直线电机换向。
永磁无刷旋转电机的两个基本部件是定子（初级线圈）和转 子（次级线圈或旋转的永磁体）。在无刷直线电机中，将转 子沿径向剖开并拉直，则成为永磁体轨道（也称为永磁体 总成）。将旋转电机的初级线圈沿径向剖开并拉直，则成为 线圈总成（也称为滑块）。在大多数无刷直线电机的应用中， 通常是永磁体总成保持静止，线圈总成运动，其原因是这 两个部件线圈总成的质量相对小。但有时将此种布置反过 来会更有利并完全可以接受。 在这两种情况中，基本电磁 工作原理是相同的，并且与旋转电机 完全一样。

3. Communication Error Codes
Current communication status is displayed in the System Menu of the UniOP. The error status is described by a message and a numeric error code. The number shows the code of the current communication error and, if the communication is correct, the code of the last error encountered. When the error code 0 is shown, it means there have been no communication errors since this system start-up.

To every controller in the network must be assigned its own unique address. You can specify controller addresses using the ‘Slave ID’ edit box in the Controller Setup dialog box. See figure above. 3) The Real Time Clock information in the Reserved Data Area (RDA) is coded in BCD. The RDA information should be placed in the UniOP Internal Buffer memory since no suitable memory areas are available in the Flex+ drive. 4) Access to the drive parameters can be obtained simple selecting the parameter name in the Define Field Dialog Box. See figure below. Parameter names have been defined according to the specification in the manual ‘Flex+ Drive Servo Controls, Installation & Operating Manual’ MN1276, Appendix B.

Linear Motor Product Characteristics Overview
Baldor offers the largest selection of linear motors and stages available to assure that you get the best linear motor solution for your application.
Take a rotary motor, split it radially along its axis of rotation and flatten it out. The result is a flat linear motor that produces direct linear force instead of torque. Why? Torque is force at a distance. Removing the distance (axis of rotation) leaves direct linear force. It follows that linear motors utilize the same controls as rotary motors. And similar to a rotary motor with rotary encoders, linear motor positioning is provided by a linear encoder.

FORCE
Imaginary process of unrolling a rotary motor.
A variation of the linear motor is the tubular linear motor. This design rolls up the motor about an axis parallel to its length. This results in a “noncommutated” motor. Designs are available with either a moving coil or moving magnets.
The same electromagnetic force that produces torque in a rotary motor also produces direct force in a linear motor. For example, a permanent magnet DC linear motor is similar to a permanent magnet DC rotary motor and an AC induction linear motor is similar to a squirrel cage induction motor.
